Technology stocks helped propel the nine-year bull market. Investors pummeled technology company stocks again on Tuesday, knocking the Standard & Poor’s 500-stock index down 1.7 percent. The Nasdaq composite, laden with technology stocks, sank 2.9 percent after a flurry of bad news about specific companies metastasized into a broad retreat from technology stocks. Nvidia has made supplying chips to self-driving vehicles a major part of its growth strategy, and Uber had selected Nvidia to outfit its fleet. The news sent Nvidia shares plunging 7.8 percent, the sharpest decline of any company in the S.&P.
