So, bad news first then? We might not be out of the woods just yet. September was an ugly month for the market with the S&P troughing down 4.9% from August’s close, and Nasdaq down 5.8%. Most would say, “Okay, that’s over! Thank you!”

But based on the latest readings from the Big Money Index (BMI), the storm might not have passed just yet. Having a good October doesn’t mean the good news starts on the first day of October. We didn’t bottom out in the S&P 500 until the 12th day of October last year.

The BMI on September 28th was 35.7. The bad news is that it is still falling. As sellers have taken control, and buying has waned, the BMI has unsurprisingly fallen. And it continues to fall.

That said, September is over, and October through December are contributors to the best quarter for stocks. Another reason why a near-oversold BMI is good news is because, if you’re familiar with the BMI, you’re familiar with what a powerful forward indicator it is – especially when it hits oversold levels.

Forward returns are significantly higher by an astonishingly high percentage of the time after the BMI goes oversold. We see this in the past 12 months, below. When the BMI goes oversold – markets tend to zoom thereafter.
