(Bloomberg) — The tech stock-rout, as steep as it’s been, has still only pushed the Index down about 8% from its November high, just shy of an official correction for a benchmark that’s more than doubled in less than two years.

But it’s much worse beneath. 

More than 36% of the stocks in the index are down at least 50% from their 52-week highs, an extraordinarily large number given the scale of the overall index’s drop, according to Ned Davis Research. According to the firm, the Nasdaq typically loses just 12.5% on average when it is less than 10% from its peak.

The break reflects how strongly the major equity benchmarks are being influenced by the technology industry’s mega-cap giants. And their stocks haven’t been hit as hard this year as some of the smaller, fast-growing tech companies that are reliant on financing and whose valuations depend heavily on future profits, making their shares particularly sensitive to higher interest rates. 

As a result, it’s unclear whether the market will break with previous patterns suggesting there’s more pain ahead. Ned Davis said the number of Nasdaq stocks that have fallen so deeply from their peaks would usually point to a “cyclical bear market,” which tends to be a short-term decline of at least 20% from records that lasts a few months. 

“Market breadth for Nasdaq stocks is pretty pathetic,” Ed Clissold, chief U.S. strategist at Ned Davis, said in an interview. “When you’re in the middle of something like this, it’s tricky to decipher whether it’s a normal rolling correction or a bull market peak. But the longer this goes on, the harder it’s going to be to ignore.” 

Since 1972, there’s only been 39 days when the Nasdaq has held within 10% of its highs while more than 35% of its members were down more than 50% from their peaks, data from Ned Davis show. They all occurred during the peak of the Internet bubble, in 1998-1999.

To be sure, the divergences won’t necessarily lead to a bear market. Clissold explained that much of the weakness in recent times has been centered around micro-cap shares, which are typically more volatile and less liquid compared to shares of larger companies.

After a short rebound at the open, tech stocks continued to be under pressure on Friday. The Nasdaq Composite was 0.5% lower in late morning trading. 

“We’ll have to see if earnings season comes to the rescue once again,” Clissold said, explaining that technical indicators like market breadth have improved over the past few quarters as corporate-profit outlooks improved. “Still, earnings revisions over the past several weeks weren’t as strong as other pre-announcement periods last year, which leads us to believe that we may not get those fantastic beat rates.”
