Recap
The day saw a solid volume of activity with 320 trades closed. The overall performance metrics indicate a positive expectancy of +0.68% per trade, supported by a profit factor of 1.62. The win rate settled at 55.9%, suggesting that the average winning trade (+3.19%) was sufficiently larger than the average losing trade (-2.51%). The notable gains, such as the +12.54% on 우리기술투자 and the +10.21% on 엔켐, provided significant positive momentum to the session. 
Lessons from the Outliers
The losses observed, particularly the -4.64% on 엘앤씨바이오 and -4.41% on 코스맥스, highlight the risk inherent even when the overall directional bias appears favorable. These declines suggest that while the broader market structure supported several profitable exits, specific names experienced sharp pullbacks that were difficult to mitigate. 
Observation Summary
The data points to a regime where successful trades captured substantial upside, as evidenced by the best performance of +12.54%. Conversely, the losses indicate that momentum can reverse quickly, even within sectors showing underlying strength. The positive expectancy, despite the notable negative outliers, suggests that the successful trades were sufficiently robust to offset the smaller losses.
