Recap
The recent set of closed trades indicates a challenging day for the portfolio. The win rate stood at 14.3%, with the average realized loss significantly outweighing the average gain, resulting in a negative expectancy of -2.67% per trade. The profit factor of 0.11 suggests that the magnitude of losses has substantially overshadowed the gains realized from the successful trades. Notable positive outcomes, such as the gain on HLB (028300) at +3.90%, were counterbalanced by larger drawdowns, including the -4.69% recorded on BGF에코머티리얼즈 (126600) and -3.87% on 한올바이오파마 (009420). 
Observations
The performance suggests that the current market environment is exposing positions to considerable downside risk. The disparity between the average win (+2.20%) and the average loss (-3.48%) points to a pattern where downside deviations are proving more impactful than upward movements. The losses incurred on names like 오뚜기 (007310) and BGF에코머티리얼즈 (126600) highlight sensitivity to broader market weakness or sector-specific headwinds that were not fully mitigated by the existing trade structure. 
For Next Time
The execution reveals that the risk management discipline needs refinement, particularly concerning position sizing relative to observed volatility. The depth of the losses, particularly the -4.69% drawdown, suggests that the initial conviction levels may have been too high given the prevailing market sentiment. The data emphasizes that even when capturing small gains, the potential for larger, swift declines remains a dominant factor in the current regime.
