# Opinion: Why any stock market rally right now will be quick

For now, the recent decline appears to have been quite modest by historical standards, smaller even than what satisfies the semi-official definition of a correction as a 10% decline. Before Thursday’s big rally, the Dow Jones Industrial Average
DJIA,
+1.29%
had fallen around 1,200 points from its previous all-time high, or 3.4%. The S&P 500
SPX,
+1.22%
was 4.0% below its high, and the Nasdaq Composite
COMP,
+0.72%
was down 7.8%.

Consider how the Nasdaq-focused market timers reacted to these declines. As you can see from the chart below, their average recommended equity exposure (as represented by the Hulbert Nasdaq Newsletter Sentiment Index, or HNNSI) fell to minus 10.7%. That means that the Nasdaq-focused market timers are now recommending that their clients allocate an average of 10.7% of their equity trading portfolios to going short. As recently as Apr. 29, this average exposure level stood at plus 83.6%.

That reflects a remarkably quick rush for the exits — 94.3 percentage points in just 10 trading sessions. In fact, out of the 5,000+ trading days since 2000, there have been only 18 — 0.3% — in which the HNNSI’s decline over the trailing 10 days was greater.

To appreciate the contrarian significance of this, consider that, on average following those past few occasions when the HNNSI declined by this much and this fast, the Nasdaq Composite was 5.3% higher in one month’s time.

Why, then, haven’t the contrarians become more bullish? The answer is also evident in the chart: The HNNSI’s plunge over the past 10 days stopped well short of the excessive bearish zone, defined as being in the bottom 10% of the historical distribution. That zone is represented by the beige-shaded box at the bottom of the chart.

The last time the HNNSI fell into that zone was in March 2020. That was when the market’s “wall of worry” became incredibly strong and was able to support an impressive rally. That wall today is not as strong.

The sentiment picture that the recent data are painting shows the market timers to be trigger-happy. They are quick to jump on the bullish bandwagon when the market rallies, and then jump on the bearish bandwagon when the market declines. As a result, both rallies and declines tend to be short-lived.

A longer-lasting rally will require more extreme bearishness among the market timers, and for them to stubbornly hold onto their bearishness in the wake of the rally’s initial liftoff. Except for that to happen, the market to itself most likely would have to suffer a worse decline than we’ve experienced in recent days. In the meantime, enjoy this rally — while it lasts.
