Traders are growing increasingly worried that this year’s stock-market rally may be all but over.

The S&P 500 Index just posted its biggest weekly range since June, and Nvidia Corp.’s good results as well as Jensen Huang’s reassurances that artificial intelligence isn’t in a bubble did little to calm investors’ nerves. Meanwhile, Bitcoin has lost about one-third of its value since hitting a record high last month, and concerns are growing over the pace of Federal Reserve cuts.
