The Financial Post reports in its Friday edition that the rapid slump in U.S. stocks over the past three weeks has been marked by dramatic falls for the biggest Wall Street names such as Nvidia and Tesla. A Financial Times dispatch to the Post reports that below the surface, however, there have been winners as well as losers as investors switch into stocks viewed as better insulated against economic concerns and cratering valuations. Since the S&P 500's record high on Feb. 19, tech stocks and high-growth companies have declined. Nvidia is down nearly 17 per cent due to concerns over China's artificial intelligence sector, while Tesla has dropped about 30 per cent, erasing previous gains after Donald Trump's election. Palantir Technologies is off about 25 per cent after reaching a record high last month amid hopes for U.S. government cuts. Among the Magnificent Seven big tech companies, Microsoft has fared best, still losing over 7 per cent. Citigroup's Drew Pettit says, "The stocks feeling this the most are the ones that have risen the most in recent years." He says there is still a "pretty good backdrop for corporate growth," adding investors now "need to buy a little bit of everything outside the Mag 7."
