Recap
The day’s closed trading activity reflects a challenging risk profile. Out of the 56 trades concluded, the win rate registered at 26.8%. The average loss magnitude (-3.12%) significantly outweighed the average gain (+2.46%), resulting in a negative expectancy of -1.62% per trade. Notable positive outcomes included gains on 두산 (+6.34%) and 쏠리드 (+4.65%), suggesting pockets of strength were identified. Conversely, losses were observed on positions such as 유진테크 (-5.28%) and 리가켐바이오 (-5.28%), indicating that downside capture was substantial when trades moved against the initial thesis 
.
Observations on Performance
The disparity between the average win and average loss suggests that while profitable trades were secured, the magnitude of the losses incurred was disproportionately large relative to the gains. The profit factor of 0.29 indicates that the total gross profit was less than one-third of the total gross loss across the closed set. This pattern suggests that risk management, particularly on the losing side, requires closer examination 
.
Lessons from Losses
The losses recorded on several names, including 리노공업 (-4.13%) and 유진테크 (-5.28%), highlight instances where the initial directional conviction proved insufficient against prevailing market resistance or flow reversals. These outcomes underscore that even when initial technical signals appear aligned, the broader market structure or foreign flow dynamics can quickly invalidate the short-term thesis. The depth of the losses suggests that the stop-loss execution, while present, was sometimes insufficient to mitigate the full downside exposure observed
