Making leveraged bets on Nvidia is likely to get much riskier if Wall Street's tech-led selloff continues. Exchange-traded funds (ETFs) designed to magnify the daily moves in the chipmaker's shares by as much as two times have been a popular vehicle for investors seeking to jump on the stock's meteoric rise this year, with total assets swelling to about $6.3 billion as of this week from only $342 million in December 2023, according to data from CFRA. But while the stock's roughly 130% year-to-date rally has rewarded bullish bets, recent turbulence in tech shares could amp up the risk for traders seeking to profit from Nvidia's gyrations. Nvidia's shares fell by nearly 7% in Wednesday's selloff, taking the leveraged ETFs down by as much as 13.5%.
