Nvidia’s Breakneck Rally Shows Signs of Overheating

Nvidia Corp. traders keep getting reasons to buy the stock, but the breakneck rally is showing signs of overheating.

The chipmaker’s 14-day relative strength index briefly topped 80 on Friday, the highest since June 2024 when the stock dropped more than 20% over the following six weeks. The momentum gauge tracks the speed of a stock’s recent price changes and a reading over 70 is a signal to some analysts that buying is at extreme levels.
