One of the most powerful and reliable signals in market history just triggered today: the Zweig Breadth Thrust.
This indicator is known for its unique ability to spot the start of major bull moves by combining breadth and momentum — showing not just how many stocks are participating, but also how quickly the shift happens.
Here’s how it works:
🔹The setup begins with the 10-day exponential moving average of advancing issues divided by advancing + declining issues on the NYSE falling below 0.40.
🔹Then, within 10 trading days, that same reading must surge above 0.615.
When you see this kind of rapid transition — from washed-out breadth to upside participation — it signals a violent shift in market internals.
And it just triggered.
According to Ryan Detrick, it’s only happened 18 times since World War II—and every single time, the S&P 500 was higher six and twelve months later.
This isn’t your everyday signal. It’s rare. It’s powerful. And historically, it has marked the beginning of major upside moves.
Let’s keep a close eye on how this one plays out.
