Inafew in a few moments will be live on the floor of the Hong Kong Stock Exchange for one last glimpse before it closes. Thursday was a huge day for Technology Company results. Four of the big global tech giants reported their latest earnings. Alphabet, googles parent company, microsoft and twitter all posted their key numbers. But lets start with a look at amazon. The retailer reported revenues of almost 41; billion in the three months betweenjuly and september thats a jump of 34 over the same period last year. But profits were virtually unchanged since last year thats because this is often the quarter when amazon chooses to pile a bunch of money into its own projects like tech gadgets, streaming video, and warehouses. The company has operated on this model for years and it seems to have served it well. In fact, analysts now estimate that amazon will command about a3. 5 of all commercial online sales this year thats nearly half of all the stuff sold online. Dave lee sums up the days action from san francisco. Amazons investors dont really mind how much profit it makes, as long as the Company Keeps on growing.

Amazons chief Executivejeff Bezos says investment in new areas like its popular alex assistant would rea p its popular alex assistant would reap dividends in the near future its popular alex assistant would reap dividends in the nearfuture if the profit right away. Alexa. Alphabet saw its Share Price Rise after beating analyst expectations thanks to more people clicking on its advertising. But alphabet is spending more and more on traffic acquisition. But the amount it has to be addressed in order to get its advertising platform in front of internet users. Thats why it is trying hard to make money in different ways. Its hard to complain about depending on a Revenue Source that is profitable but if you care about diversification it is still very heavily weighted towards research and could be an issue towards the company in the long term if someone must invest heavily in the space. This batch of tech earnings also saw some surprisingly good news for twitter. They beat every revenue, they beat monthly active users or how often people use it each month oi how often people use it each month or how many and they also grew a lot in their daily active user counter, where people show up each day so if youre an investor looking at the Long Term Health of the company they need to have more users to grow more revenue and both in this quarter grew and it was a Long Time Coming at all street was happy. A company predicted it made for the first time in its history soon be able to turn a profit. Dave lee, bbc news, san francisco.

And how nostalgic are people about their floor close and then . Closing . Look, its a bittersweet day, not just for the closing . Look, its a bittersweet day, notjust for the traders but for us also, for the media. It is also our last day he at the exchange.
