Selling pressure intensified in August as we saw the first bearish breadth thrust since mid March. I use the 10-day EMA of Advance-Decline Percent to measure breadth thrusts.
The turn of the month shows a strong bullish bias with an extremely stable equity curve that really took off the last few years. This strategy, which is only invested 38% of the time, outperformed buy and hold with a higher Compound Annual Return. Overall, the eight day percentage change at the turn of the month is positive 68% of the time for SPY. Despite strong numbers overall, February is weakest month when testing over the last twenty years, and we just happen to be in February.
Seasonality is behind price action when it comes to analysis and signals, but monthly seasonal patterns can provide a tailwind to existing trends.
