BTFD is back and better than ever

Key points:
- The S&P 500 has gone 30 sessions without suffering back-to-back losses
- This is one of the longest streaks in its history, with the Nasdaq not far behind
- Similar streaks of BTFD activity preceded gains over the next 6-12 months almost without fail
It's been a long time since back-to-back losses
The world's most venerable stock market average has had a multi-timeframe run unlike any other in its long history.
It's not alone.
The index serving as the most widely-used benchmark in the world is having a historic run of its own. Over the past 30 sessions, the S&P 500 has not suffered the ignominy of back-to-back down days.
A month without consecutive down days may not sound like much, but it is. In the index's history, it has rarely gone this long without at least small sessions of back-to-back losses. The current streak ranks among the very best since 1928.
We're more concerned with potential implications than the sheer trivia of it. So, the table below shows the S&P's forward returns after the other times investors showed such a willingness to "Buy The F***ing Dip."
It wasn't much to write home about in the short term, as even the BTFD crowd can get nervous. Over the next month, only one signal, way back in 1928, showed a gain both two and four weeks later. However, other than the pandemic-interrupted signal in 2020, any selling was minor and temporary. Over the next year, only one precedent was a loser, and that was the only signal that did not trigger when the S&P was trading near a multi-year high.
Nasdaq version
On the more tech-heavy side of the ledger, the Nasdaq Composite has had its own impressive brush with BTFD. That index has many more constituent stocks with a lot less quality, but even that hasn't prevented it from going on some long streaks without back-to-back losses.
The current streak of 32 sessions still ranks among the best since the index's inception 53 years ago. Going 32 days without consecutive losses has been a compelling sign of persistent positive sentiment. It suffered one tiny loss over the next six months out of a dozen tries and was never in negative territory over the following year. The risk/reward ratio was tilted heavily in favor of reward.
Good returns on the Nasdaq were good for other stocks, too. The S&P also witnessed only a slight loss over the next six months (a smaller one than the Nasdaq, even) and was also higher a year later every time.
What the research tells us...
Over the last couple of weeks, we've outlined the impressive momentum underlying major indices and their component stocks and sectors multiple times. This type of force is rarely seen and rarely occurs near significant and protracted declines.
The biggest negative is that the momentum is getting recognized, and investors feel left out. That typically means they will bid up prices without regard to fundamentals, which sows the seeds of its own destruction. Sentiment is elevated, for sure, which is a modest concern. It's not at levels like we saw in 2021, and so far, there are few signs that internal momentum is waning. Until we see more evidence of that, the BFTD crowd looks to have the edge, especially over longer time horizons.
