Since markets bottomed last fall, a lot of stocks (and bonds) were rising, and the buying pressure was impressive. That kind of activity tends to lead to longer-term gains.
Shorter-term is a different matter, but even that has led to only inconsistent losses. The biggest issues have come when underlying momentum wanes and we see cracks under the surface.
That's what's happening now.
Relatively few stocks have been rising on days the S&P 500 shows a gain. That difference between advancing and declining stocks has been negative enough that the McClellan Oscillator for the S&P 500 is well below zero.
It's unusual to see the Oscillator below zero, and especially well below zero, when the index itself closes at a 52-week high. The only time in recent years that it triggered was last August.
What else we're looking at
- What happened since 1928 when the S&P closes at a new high with the majority of its stocks in short-term downtrends
- Full returns since 1928 following new highs with a negative McClellan Oscillator
- A (very) long-term look at when we might see a change in long-term interest rates
- A (very) short-term look at Gamestop options
The S&P 500's McClellan Oscillator is below the zero line. Since 1928, its annualized return when the Oscillator was below zero is an abysmal -3.2%, versus well into double-digits when it's above zero.
