Amazon, flush with cash, says it will let you peek inside AWS' pants

No, investors don't care about the other 'P' word unless the company is paying a dividend which Amazon does not. Profits are taxable and tax does not end up in stockholder pockets or in investments that increase the competitiveness of the business. What investors care about is a well managed company that is able to give the market confidence so there is stock price appreciation. Evidence of a well managed company is given by the reality that it is able to hit almost zero profit year on year on a single day in the year plus or minus $200m on revenues of nearly $30bn. $200m is a big number but it less than a tenth of a percent of revenues. That's pretty good financial management especially given the revenue numbers are growing strongly providing a moving target.
