How a Top-Performing Trader Uses After-Action Reviews to Beat the Market

Erik Smolinski, a full-time trader, outperformed the S&P 500 with a 33.44% return in the first half of 2026, significantly outpacing the index’s 10.79%.

How a Top-Performing Trader Uses After-Action Reviews to Beat the Market

Smolinski treats his trading portfolio like a corporate entity, conducting quarterly earnings-style audits to determine what works and what requires a pivot. His 19-slide review for the first half of 2026 highlights a volatile landscape defined by five distinct market regimes, ranging from geopolitical drawdowns to rapid V-shaped recoveries. By categorizing these environments, he avoids the trap of applying outdated strategies to shifting market conditions.

Key observations from his analysis include a notable broadening of market leadership beyond the 'Magnificent Seven' tech giants, with small-cap stocks showing increased strength. He also tracks the speed of market rebounds; for instance, the 9.1% pullback earlier this year recovered in just 11 trading days, signaling that underlying market drivers remain robust. Looking ahead, he remains cautious regarding potential Federal Reserve rate hikes, which could stifle current momentum and force a rotation back toward mega-cap technology firms.

Individual investors can replicate this discipline without the complexity of a 19-slide deck. Smolinski suggests a periodic checkup comparing personal holdings against core benchmarks like SPY, QQQ, and IWM. This process often reveals hidden costs or underperforming assets that no longer serve an investor's original goals, proving that the most important trade is often the one where you decide to change nothing at all.
