This is how its supposed to work. The whole reason stocks have fundamental value in the first place is because they're claims on the future profits of the company. 100% of a company's earnings legally belongs to the shareholders; it's nice to see them actually returned to the shareholders (vs. blown on overpriced acquisitions) for a change.
It does mean the end of a cycle, though, and not just a "stocks go up, stocks go down" cycle. It's rational for corporate management to retain earnings and invest in future growth opportunities when the expected returns from those growth opportunities are greater than the cost of capital. That they're returning capital to shareholders, even in an era of historically low capital costs, indicates that they can't find growth opportunities at any price.
