The stock buyback boom continued apace in the first-quarter earnings season that is now drawing to a close, with U.S. companies announcing $6.1 billion of buybacks a day, according to Trim Tabs Investment Research.

That’s second only to the roughly $6.6 billion-a-day announced with fourth-quarter earnings, and is a strong indicator of exactly what companies are planning to do with savings generated by the tax revamp that was signed into law in December, said Trim Tabs.
