I don't think we are on the same page here.
If you buy Amazon stock today, assuming that they don't suddenly decide to pay a dividend what will make it worth more or less in 2 years time? Current success/size of the company is already priced in, you don't share in the profit/success of the company anyway. News has an indirect effect on price because it makes people buy/sell it (exactly the same as bitcoin - see news from China and eco concerns this week and the effect on price) but the only the direct factor influencing the price of Amazon or Google stock is the amount being bought and sold.
