Positioning in SPY: Navigating Volatility in August & September

18 ago

Disclaimer: The following article is based on a combination of data obtained from TradingView's seasonality indicator and Python code that analyzes seasonality on a 52-week basis over a 10-20 year period. The Kelly method discussed is simply a risk management tactic and should not be interpreted as financial advice. All data and analysis presented are made in good faith and are intended to advocate for data-driven position sizing rather than encouraging or discouraging any specific bullish or bearish positions. Readers should conduct their own research or consult with a financial advisor before making any investment decisions.


As we approach the late summer months, it's critical to consider the historical patterns of SPY (the S&P 500 ETF) and position oneself strategically to minimize potential losses while also capturing upside opportunities. August and September have often been challenging months for the market, characterized by heightened volatility and occasional sharp declines. However, completely staying out of the market can result in missed opportunities, especially if the market defies historical trends and rallies. Here’s how to balance these risks with a prudent strategy.

Historical Performance and Seasonality
Historically, SPY tends to experience increased volatility during the late summer, with some of the most significant drops often occurring in these months. From the data, Week 33, for instance, shows a mean return of -0.59% with only 42.86% positive returns. Week 39, even worse, shows an average return of -0.88%, with just 14.29% of the weeks ending in positive territory over the past decade.

The seasonality chart provided further reinforces this pattern, showing consistent negative returns during late August and September in previous years. This suggests a cautious approach is warranted.

Technical Indicators: Avoiding Overbought Conditions
When entering a position in SPY during this volatile period, it is essential to avoid buying when the market is overbought, as indicated by the RSI (Relative Strength Index) and Bollinger Bands (BB).

RSI Considerations: The RSI is a momentum indicator that measures the speed and change of price movements. An RSI above 70 typically signals that an asset is overbought, and a pullback may be imminent. Before entering a position, ensure that the RSI is below 70, preferably closer to 50 or lower, indicating neutral to slightly oversold conditions.

20-Day Bollinger Bands (BB): Bollinger Bands plot standard deviations above and below a moving average. When the price touches or exceeds the upper Bollinger Band, it may indicate that the asset is overbought. Waiting for the price to either move back within the bands or approach the lower band provides a better entry point.

52-Week Bollinger Bands: This is a broader timeframe that can help avoid long-term overbought conditions. Ensure SPY is not trading above the upper 52-week Bollinger Band to avoid entering at potentially unsustainable price levels.

Kelly Method and Raw Data to Consider:


Betting Calendar Using Kelly Method
Kelly Criterion for Position Sizing:
Determine Kelly Fraction:
b = net odds received on the wager
p = probability of winning (positive return)
q = probability of losing (negative return)

For each week, calculate the Kelly ratio based on historical data.
Adjust the bet size each week according to the Kelly ratio, focusing on the following:
High Kelly Ratio (>0.2): Increase exposure to TQQQ.
Moderate Kelly Ratio (0 to 0.2): Hold current positions or add conservatively.
