A Rare Bullish Sign

90/90 dayBull MarketTechnical Analysis

A Rare Bullish Sign

Friday’s market action wasn’t just a sigh of relief – it actually kicked off a somewhat rare market indicator that suggests the meltup has begun.

Some context? We’ve been critial of the stock market for its high concentration – with Nvidia and Microsoft alone making up over 15% of the weighting in the widely-followed S&P 500.

It doesn’t take a big move from either of those companies to weigh on the index. Market breadth – the percentage of total companies moving up or down – is another factor.

So what happened Friday? A rare “90/90 day.”

That’s when 90% of stocks advanced at the same time – a massive level of market breadth. And when 90% of stocks also rose on heavy volume, suggesting a fundamental shift, not a one-time reaction to news:

When these 90/90 days occur, the market is up – believe it or not 90% of the time a year later. And on average, it’s up by more than average – 23%.

“This is one of those charts that seems out of odds when they occur,” notes our Portfolio Director Andrew Packer. “90/90 days triggered often in the first few years after the Great Financial Crisis, and sure enough, stocks rose higher, even if they seemed overvalued or the economy seemed too sluggish at the time to justify the trend.”

If that’s the case this time around, the seasonal market dip this year may give way to what Grey Swan Fraternity member Mark Jeftovic has been calling a “terrifying bull market” – where stocks rally not because of fundamentals, but because investors perceive it as the place to be to avoid inflation.

P.S. Stocks weren’t the only assets that popped higher on Friday as Federal Reserve Chairman Jerome Powell hinted that rate cuts were coming, inflation or not.

Gold popped higher on the news. Makes sense in our “terrifying bull market” thesis.

And bitcoin jumped higher, although it sold off over the weekend as large players decided to take some profits off the table. Both are excellent long-term inflation-protecting assets, and gold in particular is well off of where it should trade based on our calculations.
