Recap
The trading session saw 190 closed trades, resulting in a win rate of 45.3%. The average profit realized on winning trades was 3.97%, contrasting with an average loss of 3.28% on losing trades. The performance metrics indicate a profit factor of 1.00, suggesting that gains and losses were balanced across the observed trades. Notable positive outcomes included significant gains in Cosmax (192820) at +15.45% and J&T C (204270) at +14.51%. Conversely, the session also recorded notable drawdowns, such as those observed in Pearl Abyss (263750) at -12.00% and Novarex (194700) at -10.53%. 
Observations from Outcomes
The spread between the best recorded gain (+15.45%) and the worst recorded loss (-12.00%) suggests that while substantial upside potential was captured in certain names, the downside risk materialized with similar magnitude. The consistent pattern of positive expectancy, despite the mixed results, points toward the overall structure of the executed trades. The losses, particularly those exceeding 10%, highlight instances where the market moved against the established directional bias. 
For Next Time
The trades that resulted in losses, such as those in Pearl Abyss (263750) and Classys (214150), suggest that momentum reversals or sudden shifts in sector sentiment can rapidly erode gains. The magnitude of the losses relative to the average win size indicates that the risk management applied during those specific trades requires further review. The data reflects a period of mixed directional conviction across the KOSPI constituents.
