Recap
The day’s closed trading activity reflects a challenging pattern. With a win rate at 30.8% and a negative expectancy of -0.94% per trade, the overall performance suggests that the average loss magnitude is currently outweighing the average gain. The profit factor of 0.48 indicates that the realized gains have struggled to compensate for the losses incurred. Notable positive outcomes, such as the gains on 제이앤티씨 and 성호전자, were offset by losses recorded on names like 안랩 and 삼표시멘트. 
Observations
The performance metrics suggest that the execution environment has been difficult, as evidenced by the negative expectancy. The disparity between the average win (+2.85%) and average loss (-2.62%) is relatively narrow, which, when combined with the low profit factor, points to a need for greater risk management across the sampled trades. The magnitude of the best gain (+14.37%) versus the worst loss (-6.31%) shows a significant range, indicating moments of strong directional conviction that were not consistently maintained across the portfolio.
For Next Time
The losses observed today, particularly those on established names like 안랩 and 삼표시멘트, suggest that momentum can reverse sharply even when initial setups appear sound. The negative expectancy derived from the closed trades highlights that the cost basis management needs careful review.
