Nasdaq 100’s Sizzling Run to Record Flashes Warning

The tech-heavy Nasdaq 100 Index is showing serious signs of overheating, an indication that a selloff might be right around the corner.

After surging 10% in the past month, the benchmark -- home of the likes of Apple Inc., Amazon.com Inc. and Microsoft Corp. -- has seen its relative strength indicator, a 0-100 gauge of bullish and bearish price momentum, soar to 78, well into overbought territory. That’s seen by traders as a contrarian signal that a decline is imminent, because buying has gotten excessive. Four of the last five times the indicator hit such a level, the Nasdaq 100 shed 12% or more to the ensuing low.

In the first signs of a pullback, the Nasdaq 100 fell Monday for the first time in 11 sessions, snapping the longest winning streak since December 2020. The index sank further Tuesday, dropping as much as 0.8% in early trading, dented by a pullback in Tesla Inc.

“The biggest drivers of the Nasdaq 100 performance over the last month have really been concentrated in a few high-performing stocks, which is notable,” said Chris Berthe, global co-head of cash equities trading at JPMorgan Chase & Co. Indeed, in the past month, Tesla Inc. and Nvidia were among the biggest gainers, adding several hundred billions of dollars in market value.

The latest leg of the rally to a record high had also been fueled by a string of earnings beats from technology companies and the Federal Reserve’s dovish messaging on rate hikes, helping the index beat the S&P 500 by more than three percentage points since the reporting season began in mid-October. But the outperformance can’t go on forever.
