Recap
The day saw a moderate number of closed trades, resulting in a positive expectancy of +0.23% per trade. The win rate settled at 48.3%, which is slightly below the 50% mark. The average winning trade (+2.81%) was notably larger than the average losing trade (-2.18%), contributing positively to the overall profit factor of 1.20. The best performance came from 오스코텍 (039200) at +6.43%, while the largest drawdown was observed in 코스모화학 (005420) at -3.86%. It is encouraging to see several solid gains, such as those from 인텔리안테크 (189300) and 나노신소재 (121600), which provided a nice lift to the overall performance today 
.
Observations from Losses
The trades that closed at a loss, particularly those in 코스모화학 (005420) and 덕산네오룩스 (213420), highlighted instances where the initial momentum faltered quickly. These exits demonstrated that even when the initial thesis appears sound, the market can swiftly reverse course, leading to losses that are substantial relative to the average win size. These outcomes serve as a clear reminder that the strength of a position must be maintained through the entire holding period, not just at the point of entry 
.
For Next Time
The overall structure of the day suggests that while profitable trades exist, the frequency of losses keeps the overall picture balanced. The positive average win versus the negative average loss indicates that the successful trades are doing the heavy lifting. It is helpful to observe the magnitude of the best gains relative to the worst losses to gauge the risk-reward balance achieved across the sampled trades. This process is purely for reviewing historical outcomes and does not constitute any form of investment guidance.
