US corporations will buy back their own stock at a record clip of $1 trillion this year, according to an analysis issued by Goldman Sachs on Monday. The Wall Street giant attributed the surge in share repurchases to booming corporate profits and Trump’s $1.5 trillion tax cut for corporations and the wealthy, which was passed by Congress and signed into law last December. In a note to investors, David Kostin, chief equity strategist at Goldman, gushed that investors were likely to see the impact of the buybacks in higher share prices and fatter stock portfolios very quickly. The scale of the buyback spree is massive. Second-quarter 2018 stock repurchases are up 57 percent from the same period a year earlier. In the tech sector, the year-over-year increase is 130 percent.
