When searching for a trading system or investment method, common sense is your greatest ally. To illustrate, let’s examine the performance of two popular ETFs, Invesco QQQ (QQQ) and SPDR S&P 500 (SPY), over the last 10 years, and a 50-50 portfolio combining them. Their historical data provides a clear benchmark for evaluating any strategy.
Over the past decade (ending July 1, 2025), QQQ, which tracks the NASDAQ-100 Index, delivered a compound annual growth rate (CAGR) of 18.61%. However, it experienced a maximum drawdown of 35.12%, reflecting its higher volatility due to its tech-heavy composition. In contrast, SPY, which mirrors the S&P 500, achieved a CAGR of 13.51% with a maximum drawdown of 33.72%, offering a more stable but lower return profile. A 50-50 portfolio of QQQ and SPY, rebalanced periodically, yielded a CAGR of 16.13% and a maximum drawdown of 34.42%, striking a balance between growth and risk.
These figures set a straightforward standard. Whether you’re a short-term trader, mid-term swing trader, or long-term investor, ask yourself: can your method consistently outperform these simple, passive investments? QQQ and SPY require minimal effort—just buy and hold. If your complex strategy, with its indicators, algorithms, or frequent trades, fails to surpass their returns or exposes you to greater drawdowns, it’s time to pause and reflect.
Common sense demands simplicity and effectiveness. If you can’t beat a basic ETF portfolio, question your approach. Are you overcomplicating things? Are you taking unnecessary risks? Use these benchmarks as a reality check to ensure your trading or investing method aligns with practical, achievable goals.
