Recap
The trading session saw 93 closed trades, resulting in a positive expectancy of +1.64% per trade and a profit factor of 2.90. The win rate stood at 69.9%, indicating a favorable risk-reward profile for the period. The average winning trade yielded a gain of +3.58%, significantly outpacing the average loss of -2.87%. Notable positive outcomes included significant gains on 우리기술투자 and 원익홀딩스, which contributed strongly to the overall positive return. 
Observations from Drawdowns
The losses recorded, such as those on 현대바이오 and 펌텍코리아, highlight instances where momentum reversed sharply after initial gains. These outcomes suggest that while identifying strong directional moves is effective, the market can rapidly correct positions that have appreciated significantly. The spread between the best gain (+13.46%) and the worst loss (-5.38%) shows a substantial range of outcomes captured across the portfolio. 
For Next Time
The performance metrics suggest that the positive skew from winning trades is robust, given the high win rate and strong profit factor. The losses encountered, while manageable within the overall positive expectancy, underscore the necessity of acknowledging periods of sharp mean reversion. It is clear that while capitalizing on established trends is effective, the risk management around overextended positions requires continued attention.
