Recap
The day’s closed activity reflects a challenging pattern. Out of the 231 trades concluded, the win rate stood at 24.2%. The average expected return per trade was negative at -2.17%. The profit factor of 0.28 suggests that the magnitude of losses significantly outweighed the gains realized. Notable positive outcomes, such as the gains in 티에스이 and ISC, were offset by substantial drawdowns observed in positions like 서진시스템 and 원익홀딩스. The spread between the best recorded gain (+10.94%) and the worst loss (-9.26%) indicates significant volatility was encountered across the sampled trades 
.
Observations from Losses
The losses incurred, particularly those exceeding 6% in magnitude, suggest that the market structure presented considerable headwinds against the executed trades. The negative expectancy, despite some large wins, points to a systemic drag across the sampled set of trades. The depth of the losses relative to the average win size suggests that risk management parameters were breached or that the prevailing market regime was significantly adverse to the prevailing directional biases 
.
For Next Time
The performance metrics—specifically the low profit factor and negative expectancy—indicate that the recent trading period has been characterized by difficulty in maintaining positive risk-adjusted returns. The observed pattern suggests that caution regarding directional conviction is warranted as the broader KOSPI trend remains subdued. This analysis is based solely on historical trade outcomes and does not constitute investment advice.
