"bloomberg west" is next. ♪ emily: i am emily chang, and this is "bloomberg west." coming up, the oracle logs on. warren buffett comes out swinging with two big bets on tech. we will break down the berkshire-apple connection. apple turned heads when it jumped into the passenger seat with didi. we will have details on a potential ipo. reportedly working on its own private labels for things like baby products, snacks, and household items. there is a launch planned for next month. our lead, warren buffett, the oracle of omaha, has disclosed a $1 billion stake in apple, announcing it bought 9.8 one billion shares sometime in the first quarter. buffett has historically stayed away from tech, saying he doesn't understand it. in late 2011, buffett acquired a 5% stake in ibm. shares are down some 20%. apple shares popped on news of buffett's buy, but the road ahead for apple isn't shiny. carl icahn just disclosed he no longer has a stake in the company. discuss, shira ovide from new york as well as reporter noah bureau how. i will start with you. what buffett has said is one of his two investment managers made this investment and didn't it.ult him on what do you read into this big bet on apple? noah: there is nothing nefarious going on. buffett has two deputy investment managers. he in trusts of them with $9 billion each of berkshire's capital that they go out and get to invest in a way they see fit. what we have seen is one of these guys, they happen to be younger than buffett who is 85 hisf these deputies is in 40's, another in his 50's -- one of those guys liked what he saw and put $1 billion to work for apple in the first quarter. i spoke with a lot of investors today, and some of the themes they were hitting on is that apple has a ton of cash. it was trading at a pretty low multiple, and so investors that like good value, maybe there was some opportunity there. emily: the two investment managers we are talking about, weschler.it'sd interesting that the one tech bet buffett has made hasn't panned out. all tech isn't all the same, but given the history of ibm, how does that and your thinking around this investment? the ibmbviously, investment was buffett himself, and this apple investment isn't. that ibm investment has been one of berkshire's worst investments. buffett bought it at a high point for the stock, and since has basically turned in quarter after quarter after quarter of revenue declines. the stock price, as you said, is down about 20% from the point buffett disclosed his investment. he has made one not very good investment. let's hope that todd and ted make a better deal with apple. emily: buffett has made many great investments and a few not great ones. the question is, is apple the next candor morgan or 21st century foxy? noah: it certainly seems like it is more in that range. know, maybe it does well. the one thing we can say about ted and todd is they have similar long-term horizons like buffett does. to be lessing interested in apple's next quarter results then they will be in where apple is a couple years from now. one theme i heard repeatedly from investors i spoke with is that they are likely going to let some of these bets that apple has beyond self driving cars or other things they have in development play out. that is where the opportunity lies. emily: of course, they just made an investment in didi, the uber of china. we are going to get to that later in the show. i also want to talk about yahoo!. buffett is backing in a group bidding for the struggling company's assets. i want to bring in m&a reporter alex sherman who has been covering the slow march of yahoo!'s sales process. what do you make of the fact that buffett would be supporting this bid? --says it's not a perfect personal stake, but i am providing financing. alex: it's a little uprising on the face of it from what we just talked about. i can answer this question in two ways. maybe yahoo! isn't a tech company. maybe it's more of a media company. lauren cop -- warren buffett does have a history investing in media companies. he invested in directv not too long ago. it's possible that warren buffett listens to dan gilbert's pitch. and buffett have a relationship. may be buffett decided, look, give me enough protection, and if gilbert is working with ex-yahoo! folks, they may decide the core business is worth zero. maybe they convinced him the company isn't going to go bankrupt, and therefore, it was a decent investment for him to make. on the other side of it, we can't really explain what yahoo! is. if tech investments in general are off limits for warren buffett, you would have to understand why yahoo!, of all tech companies, would be something that would intrigue him. ah, buffett did help burger king takeover tim hortons. -- $5 billionion into goldman sachs. does yahoo! make sense in the context of those investments? noah: sure. noah:the way to look at this is it's a financing arrangement. berkshire has a huge balance sheet, and buffett brings his reputation to the table. it lens instant credibility to to buywho is trying another company. because of that, he is usually able to get incredible terms, and it's a way for him to put some of berkshires money to work for not so long and for some money. as you said, he is lending his name to this potential deal, and you have not been optimistic about the future of yahoo! if you think about it as a media company as opposed to technology company, may be buffett has more experience making media bets -- buffett has mark's parents making media bets, but he seems to think there is some hope here. shira: as no less said, i think this is more about backing dan gilbert then it is making an investment that on yahoo! buffett doesn't make bad deals like this come even if you think back to the financial crisis. he invested in companies like bank of america, goldman sachs at distressed points in those companies' history. tonegotiates terms favorable him. i suspect a similar arrangement would be worked out where buffett gets his money back or gets some kind of dividend or some other kind of sweetener that an ordinary investor without his gravitas could never get. likelihood of the this actually happening, and b, how quickly can we expect the sales process to proceed? alex: on the first point, we should note that this could be a footnote in history. this is not an actual investment yet. i still think verizon is the favorite to buy yahoo! it's possible that buffetts presents might boost verizon to pay out a little bit more. away, i haveks heard. it's not days away. how many weeks, i'm not sure. at some point, there will be a will comefinal bids in, and likely at that point, verizon will have the opportunity to say yes or no. verizon, the gilbert and buffett and private equity firms involved are the next level tier buyer. emily: alex sherman, shira ovide, and noah buyohor. thank you all for weighing in. looking at some of the filings of major investors, david tepper's shed his apple stock, while bridgewater associates cut its investment by two thirds. carl icahn exited stakes in six companies, including apple, last month. coming up, could didi chuxing be the first ride-hailer to go public yet go we will break down on how -- breakdown how apple's investment could pay off. our next guest discusses why one city could snatch the title of the world's most innovative tech hub in the near future. ♪ emily: to a story we are watching, facebook ceo mark zuckerberg has invited a group of conservative leaders for a meeting at the company's headquarters in menlo park. according to the associated press, attendees will include radio host glenn back, former white house press secretary dana perino, and donald trump campaign advisor barry bennett. this after reports that facebook employees are more involved in choosing stories for the trending topics section than we have been led to believe. next contractor claimed facebook conservativey stories. facebook responded by saying the trending topics section is governed mostly by algorithms, not humans. trade association for publishers, 43% of social media users to know where the stories they read on facebook appeared, underscoring the power facebook has in shaping what we consider to be important news. facebook has not confirmed additional details of the meeting. turning to apple, tim cook twitter to make a public display of his latest investment. the apple ceo hailed a cab with didi chuxing in beijing, this after apple made its $1 billion investment in the company last week. it may not be long before apple can cash in on this investment. ipo in targeting a u.s. 2017, but the timing will depend on the outcome of its battle for market share with uber in china. the latest funding round valued didi at 26 billion dollars, while uber comes in at $65 billion. didi does have the china advantage. the company claims it controls 99% of the country's mobile-hailing market. didi is denying these ipo claims. first of all, let's start on the ipo. what do we know? report is from us, 2017, we could be considering an ipo in new york, depending on the competitive environment with uber. there is definitely some wiggle room. emily: didi has denied the report. is still pretty speculative, but it sets up a timeframe for when we should be thinking about an ipo. emily: you just spent several weeks in china, and i know you use both services. what did you think? >> i think it's pretty clear that there is one service that needs to work on quality a little bit. does have some ways to go in terms of quality. emily: how so? >> drivers arriving on time, knowing the city. didi has a little bit more of an edge because they are supposedly paying higher wages, therefore getting drivers who know the city better. these are all telltale stories in beijing. people tell you where a lot of far away, androm, they come to the city for the first time. they don't really know the city. there is a lot of work to be done. emily: i was in beijing, and i used both services. i didn't see a huge difference, but i think if we had gone further out to the city edges, it probably would have been more difficult. what do you make of apple's investment? cyriac: i think it is probably a smart move on apple to get into the chinese market. the service will benefit from it, as well as, we all know there is a government investment in china.n didi use got this situation where you've got a government investor, and you've got apple trying to get along with the government in china, as well. they are common investors in the same company, and then you've got this interesting trifecta of and 10 send an alibaba -- nd alibaba. part,ompares to the didi which is apple and the chinese government. an interesting lineup. this is politics at a very high level. emily: when the president of didi was here, we asked about the relationship to the government and how open are to thes -- regulators idea of a car sharing service. >> the chinese government has been more and more open to us. the supply issue is the top issue in general. the chinese government understands, we need to utilize the existing resource to put into the system so people can travel. emily: china's government has made it impossible for companies like facebook and twitter and google to succeed in china. could they do the same thing to uber? eric: i think here there is a huge economic need to this when there is a lot of economic anxiety in china. that isan industry creating a lot of jobs. that is to uber's advantage. this isn't one of these critical industries. it's not a media company. it's about transportation. wilbur sort of hopes it won't get categorized the same way facebook and other countries are. emily: as someone who has run a private company, do you think ori should go public in 2017 as soon as that, or should they continue to raise money? cyriac: i think it depends on their international plans, whether they only want to focus on china, or whether there are other markets. it also depends on, at some point, what is the financing need? they are supposedly burning, both of them, uber and didi, $1 billion a year. cyriac: they are both burning a lot of money. that is just in china for uber. approaching ory going above $2 billion last year in losses. they are losing a lot of money. for uber, it is more than just china. going to continue to discuss your trip to china with us after the break. eric newcomer, thanks so much. weeks, aafter three grilling 24 chinese s start-ups. cyriac is back on the city that could steal silicon valley's reputation as tech hub. ♪ emily: on today's funding board, asia's biggest internet company tensen is likely to raise as much $4 billion in a syndicated loan. last month, the company hired banks to aim for a $1.5 billion demand. has seen strong the update highlights a theme among china's internet giants. we have reported by do is loan, and$1 billion alibaba was seeking as much as $4 billion last month. these companies are taking advantage of the funding opportunities. to discuss china's tech startup scene versus silicon valley's is angel investor cyriac rhoding. you were in beijing for three weeks. you talked to a lot of entrepreneurs. one thing peter thiel told me when he got back from china that he is scared of the chinese tech community, because he thinks there is so much power. should we be afraid? cyriac: i'm not scared at all. i think it's awesome. can do foring we silicon valley is to get some impulse from the outside from time to time. it's important we don't become totally self absorbed and believe this is the only place in the world something is happening. when you go to china, go to beijing, you can sense the entrepreneurship in the air. what i loved about it and what i was inspired by was the openness, the friendliness, and i have to say, the raw authenticity of entrepreneurship. what entrepreneurship should be is to create something great out of almost nothing. emily: do you think it will be the next silicon valley or adjacent? cyriac: i think it's a competitor. i'm european by background, so it hurts me to say that, but i have to say i don't think there is any other place in the world besides beijing, not even china, that is a true competitor in the next decade to silicon valley. india might be the only contender, but what is going on in beijing is very impressive. the engineering talent from the twoto universities -- universities and the sheer amount of money available, and then the entrepreneurs and the hunger to move fast, and most importantly, there are 1.3 billion people in china. most of the argument is, they don't have the money to spend. what do you think about how many smartphones are in the united states? 190 million. in china today, 530 million. in three years from today, over 700 million. that group has enough money to have a smart phone. most of them have never had internet access before they get a smartphone. everything is new to them. they love it. emily: one of the guys making smart phones in china is hugo barra who used to work at google. you talked about your midnight meeting with hugo and the long hours that these entrepreneurs keep. we also had our own midnight meeting with hugo barra. you talk about work ethic, and it's intense. cyriac: it's intense. there is no work-life balance as we know it. 9-9-sixsomething called in chinese startups. it means from 9:00 a.m. to 9:00 p.m. six days a week. for founders, top executives, it is more like 9-11-6.5. noother words, there is private life. im not a defender or proponent of working like crazy. who is a good leader when you are always tired and don't even know your kids? what is inspiring and impressive is the amount of hunger and dedication and drive that is behind that. that is great. emily: you do have one quick criticism, the get rich quick mentality. the most recent batch of entrepreneurs is driven by financial returns quickly, and that will not work when the next wave comes, which is innovation-based startups of verses cloning. you need to focus on other things that drive you, and that is coming out. so much for you joining us and sharing your travels. we will be talking about amazon upping the ante on private labels, putting the heat on big-box retailers. ♪ show me top new artist. ah, ha ha. show me top male artist. my whole belieber fan group. it's not a competition, but if it was i won. xfinity x1 lets you access the greatest library of billboard music awards moments, simply by using your voice. the billboard music awards, live sunday may 22nd, 8/5 pacific, only on abc. shery ahn: let's start with a on news. u.s. investigators are preparing a conclusion for a meeting tomorrow that the amtrak at the controls of a speeding train that derailed in philadelphia last year was distracted moments before the accident. that is according to two people briefed on the discussions who say they found no evidence of drugs or alcohol. died, and more than 200 others were injured. after stalling for months, congress is ready to move on president obama's request for additional money to fight zika virus. the virus has been linked to serious earth defects and other health problems. house republicans released legislation to provide 620 $2 million and a $1.1 billion measure is expected to be endorsed by the senate tomorrow. a second judge has ruled to allow the extradition of el chapo to the u.s. the process awaits approval of mexico's foreign ministry. his lawyers can appeal, meaning it could take months for him to be tried in america. 100,000 laps around earth for the international space station, which reached the orbital milestone earlier today after 17.5 years. nasa says those 100,000 orbits are akin to traveling more than 2.6 billion miles. that is about 10 round trips to mars, almost one way to neptune. dayal news 24 hours a powered by our journalists around the world. we are now joined by paul allen in sydney with a look at the markets. good morning, paul. paul: it is looking like a pretty good day across the region after u.s. equities as well.gher, and oil, new zealand, currently the only market up and running, already up 0.5%. we are expecting gains locally nikkei.sx 200 and the is expecting a profit for the year of just under 8 billion, much worse than expected. westpac banking shares will be interesting to watch in australia after the regulator released more details of its probe into the bank, accusing it of attempting to fix the bank bill swap rate. this is australia's equivalent of libor. denies the allegations. also out today, the reserve bank of australia minutes for the previous meeting. we will be looking for some more clues as to where we might be going in the future. i am paul allen for bloomberg tv in sydney, australia. ♪ amazon is upping the ante, planning to roll out privately-labeled goods across our range of categories, like perishable foods and household items like laundry detergent. these plans have been in the works for several years and could appear on the site by the beginning of june. under brand names like happy belly and mama bear. how big could this business be for amazon, and what does it mean for the competition? i'm joined by our editor at large cory john. mark, i will start with you. have you heard anything about this, and how big of a business could this become? mark: it has been building up for a few years. they had something called elements. emily: with baby wipes. mark: also with linens, pillowcases. emily: they also have a fashion line. it is one of their fastest-growing businesses. they have had some history with this. the upside for amazon, it's higher margins. anything that brings margins up is a good thing, and extends the appeal of the prime service. tose products are available prime subscribers. in the u.s., there are about 50 million. emily: companies as big as walmart have their own private label brand. it's par for the course when you are a big real -- retailer. y: i think what is interesting, as mark mentions, it's a lower margin for them, but maybe they don't take that margin. maybe they have lower prices. this would allow them to gain market share. the risk with a private label is, are you offended the people for whom you are trying to sell their goods? amazon has been in the drivers and one wonders if this might affect those relationships. emily: what about some other risks? with element, they plan to make diapers, but they pulled the diapers from the market. when you are making things like food, that carries additional responsibility, right? mark: there will be more product risk, but i like what you just said, cory. the famous quote attributed to jeff bezos is "your margin is my opportunity." he could look at the margins that other white label companies have and take half of that and take the rest as lower prices. it would be classic amazon style. yes, there is more product risk, but this company is pretty good at managing a lot of different operational risks. they will have a couple misses like fire phones, but generally, they have been right. emily: what does this mean for amazon vendors? cory: they gather so much data with the way their vendors sell stuff. they have been making lots of goods without any kind of label when they have seen opportunities for a lower price and to take some margin. the risk is that some of the sellers are going to get ticked off and pull their business or make the pricing a little bit higher. there together data. think about tied soap. for other canisters of tied soap they have sold, they have learned so much about those customers. the people of procter & gamble won't be thrilled about them making a competitive product. emily: what does amazon have on other competitors? mark: the problem is going to be, where are those other vendors going to go for liquidity? you could go to ebay, but last time i checked, they are showing no growth. there are very few brands that have that kind of pull to go directly to customers. amazon is a low-customer service channel for retailers and manufacturers. the amazon customer is extremely well educated, and they are in and out. emily: could you hazard to guess as to how big in dollar terms this business could be? mark: a private white label business, we are doing $100 billion in sales annually. it's hard to know how much of this will be incremental. it's not like it's going to draw away from third-party sales on amazon sites. emily: as a percentage of nantz, it's a question of how many products they are going to launch. what is interesting is they are drawing a lot of products. wonders, are they going to take a margin, or are they going to lower price and not take a margin? is there a new philosophy happening at amazon? are they going to continue to run retail on a no-profit basis? emily: any idea how successful amazon echo has been? mark: very successful in our household. emily: my son loves it. way: i think this is the into amazon fresh, into groceries. it's an extremely efficient consumer experience when you can have one of these in the kitchen andsay, "alexa, order," then go through the list of what you want for your refrigerator. emily: when a three-year-old can ask a knock knock choke and get an answer at any time, that's a success. , mark mahaney, thank you both. let's take a look at the shifting sands of health tech. wireless carriers tried to get into the space, thinking a move towards telemedicine would open up new revenue streams. instead, it's tech china and sleeping into the space. take a listen. the u.s. telemedicine market could double in more than 30 years. initially, the large telecoms companies, the likes of verizon and at&t, were poised to benefit, but now, it's apple and alphabetic who are deepening their investments. alphabet uses technology to address existing disease. on a working with novartis smart contact lens that monitors glucose levels. calico, another division of alphabet, is developing new drugs with much of its research focused on aging. committed $153v million to help startups -- health startups in 2015. apple is developing an ecosystem of health apps. health kit comes preloaded on iphones, paring with fitness devices so users can monitor their data. research kit enables iphone users to participate in large medical studies. these bets haven't paid off yet, but we will be watching for when they do. emily: a news update -- twitter ,ust named deborah l. lee chairman and ceo of the two networks, to its board. lee has been ceo for more than a decade at viacom. she is the first african-american on twitter's board. lending club says it has received a grand jury subpoena from the u.s. department of justice, lending club saying "the company intends to cooperate with the doj in a regulatory filing." the company plunged 51% last week after the surprise departure of its ceo. lending club stunned shareholders by announcing the founder had resigned after internal reviews. coming up, google's annual developers conference is this week. last week, we learned about marshmallow. now we are looking for details about the newest operating system. ♪ emily: a legal battle between the managers of the harvard-linked venture-capital firm the x fund has entered a new phase. hugo van buren is suing his partner for a breach of fiduciary duty, defamation, and fraud. among the claims, van buren alleges that he amended files. i asked chung about the infighting in the x fund. >> the thing that happens in a lot of the firms we work with, when you are growing fast, things sometimes get broken. it's unfortunate the way things turned out. the good news is we are moving forward. on friday, the x fund's chungs voted to allow to continue funding in startups. the busy week ahead in tech, i want to kick things off with google hosting its annual developers conference, google io . ceo on the agenda, facebook mark zuckerberg will be hosting conservative leaders wednesday at the company's headquarters, discussing allegations that trend in articles were biased against right-leaning news. salesforce will release quarterly earnings after the bell wednesday. here with me to break it down, tom giles and jack clark, who covers google and cerebral -- salesforce. what are we expecting?

he will be at the meeting from all outward appearances. it just underscores to him the urgency, and it also shows -- you saw this escalation. report,ed out as this and the initial response was, no, this is automated. there is little human involvement. there was an update to that that showed there was more human involvement than you might have thought, and finally, mark zuckerberg comes out. in the midst of all of this, you have had conservative lawmakers weighing in. mark zuckerberg is saying, we are going to take a look at this closely, which is indicating that maybe they didn't know what was going on. tom: he has taken a very personal involvement in it. it's hard to say how much he was is showing he's going to be personally involved. emily: what is the latest facebook is saying about human versus algorithm? tom: it's a combination of the two. the statements show that there is very much a human element. wednesday, facebook is going to -- it has been talked about in the conservative media as this padding on the head, and in no way can mark zuckerberg come across as condescending when he sits down with these conservative leaders. emily: salesforce, what are we expecting?
