Question 6

How does ORLY DCA compare to the S&P 500?

Accepted Answer

Enhanced DCA into ORLY returned 30% over the past 5 years. The S&P 500 (SPY) returned approximately 53% over the same period. ORLY's performance reflects its volatility as a consumer discretionary asset. Enhanced DCA underperformed standard DCA by 1% over this period, showing signal-based timing doesn't always beat regular-interval buying.

Question 7

What is the risk of dollar cost averaging into ORLY?

Accepted Answer

Past backtest performance does not guarantee future results. ORLY is a consumer discretionary asset whose price can fall as well as rise. While DCA reduces timing risk by spreading purchases over time, losses are still possible if the price declines significantly. Always invest within your risk tolerance and consider your overall portfolio diversification.

Question 8

What is the O’Reilly Automotive dollar cost averaging strategy?

Accepted Answer

Standard DCA invests a fixed amount ($100/week or $433/month) into ORLY at regular intervals. Enhanced DCA improves on this by using RSI (Relative Strength Index) signals to increase buy amounts during market dips (oversold conditions) and reduce or skip purchases when the stock is overextended. Over the 5-year backtest, this timing approach has delivered 1% lower returns than standard DCA while deploying less total capital into ORLY.
