Recap
The day’s closed activity shows a positive expectancy of +0.57% per trade, supported by a win rate of 53.6% and a profit factor of 1.38. The average winning trade (+3.83%) notably exceeded the average losing trade (-3.20%), which is a constructive indicator of the overall edge captured. Specific notable gains included 금호타이어 (+11.38%) and 대한항공 (+9.87%), suggesting successful captures in cyclical or sector-specific strength areas. Conversely, losses were observed in names such as 주성엔지니어링 (-8.85%) and 티에스이 (-7.11%), indicating instances where the market moved against the established thesis. 
Lessons from Underperformance
The losses recorded, particularly the depth seen in 주성엔지니어링 and 오늘이엔엠, highlight the importance of managing drawdowns when initial momentum stalls. The negative outcomes suggest that while the overall directional bias was sound enough to generate positive expectancy, the execution was susceptible to sharp, immediate reversals. These instances underscore that even when macro themes appear favorable, individual stock resilience to intraday selling pressure remains a critical variable to monitor. 
Market Observation
The performance metrics suggest that the captured gains were sufficiently robust to offset the losses, leading to a net positive outcome for the closed trades. The disparity between the best gain (+11.38%) and the worst loss (-8.85%) indicates that the successful trades captured significant upside momentum, which was valuable for the overall positive drift observed today.
