From an in vestment vise from 4. 5 billion. Good to see you tar yak. And in the pieces by julia and josh is this simplies a function of high valuations and the air coming out of the stocks or are we seeing companies that are increasingly becoming less relevant . I think it is probably the former. What we see in technology is you have to break it up into the momentum the social media stocks with the fast money following those and then the Old School Tech stocks like microsoft and cisc you saw microsoft, the stock is up 15 . So broadly taken you have to bifurcate the sector. We have investing in longterm and not just eyeballs similar to what we had three years ago. Do you think stocks will be as good relatively as the last three years. Over the last three years weve had 3 , over the mean we expect high singledigit and that will be a road. We havent had the 3 in the last three years. But if you come out of that and we are up 30 , that is a good enough to look forward to.

As we see oil below the 100 range, the consumer is in a better range and they are paying off debt and getting higher wage and nordstrom is a focus because they are focused on the high end consumer and what we like are a couple of things one it is omni channel but it is not just going to the store but ordering online and online and offline, they are there and they are about to sell off the credit card business which could raise a couple of billion dollars which they could reinvest or buy shares. And delphi. And going back into the consumer them as the consumer spends more money, delphi is increasing the digital contents in all auto companies, not just here in the u. S.

As we head into the spring weekend, house hunters are on the prowl. And while were still in the early spring of the housing recovery the market right now is hot and very competitive. Diana olick has advice if you are looking to bid and to buy. Very tight supply in housing markets across the nation and it is leading to bidding wars. Onethird of all u. S. Properties sold in march went at or above asking price. So how do you emerge the winner in a bidding battle . Prepare your finances and carry cash. Get preapproved for a loan now. Home sellers are leery of loans that might not be set in stone. If you can, bring cash to the table so that if the appraisal comes in low you can cover the difference. Offer fast and strong. Be the first to offer and dont insult. Nothing turns a seller off more than someone under valuing a prized possession. Come in at or slightly below offering so they know you are serious. Increase the offer if there are other bids. So say the Purchase Price of the home is 400,000 but you expect it could go as high as 450,000 dollars. T in an escalation clause sa you are willing to go as high as 460,000 dollars but only go above competing offers. Get a preinspection and do it befo submitting an offer. Yes, it will cost you a few hundred dollars but selling hate contingencies on a contract. Show the love. If you love love love the house then let the seller know it. Directly or through your real estate agent. Dont be afraid to write a letter send a picture of your kids and be specific. Be smart and not sappy. Research the market look at comparable homes that just sold visit the local school have coffee at the closest starbucks and chat with the neighbors. And then dont let mer remotions steal your wallet. Whatev house you are looking at it is not the only house you could be happy in. For nightly Business Report, im diana olick in wish. And for more tips head to our website at nbr. Com.
