Recap
The day’s closed trading activity shows a mixed outcome. Out of 131 trades closed, the win rate registered at 37.4%, with an average expectancy of -0.46% per trade. The profit factor of 0.78 indicates that the average loss magnitude outweighed the average gain magnitude. Notable positive returns were observed in SFA반도체 (+14.38%), 제이앤티씨 (+12.82%), and 에프에스티 (+10.95%). Conversely, the losses were significant, highlighted by 오름테라퓨틱 (-30.09%) and OCI홀딩스 (-6.90%). The spread between the best gain and the worst loss (-30.09% vs. +14.38%) suggests considerable volatility was encountered across the sampled names 
.
Observations
The performance metrics suggest that the average loss size (-3.36%) was substantial relative to the average win size (+4.40%). The depth of the losses, particularly the -30.09% recorded, points to instances where the underlying market structure or sector momentum proved difficult to navigate. These outcomes underscore that even when identifying specific high-momentum names, the broader market context can quickly invalidate initial directional assumptions 
.
For Next Time
The recorded losses, particularly those exceeding 5% in magnitude, suggest a sensitivity to broader market risk-off sentiment or sector rotation that was not fully accounted for in the trade execution. The disparity between the positive and negative outcomes suggests that risk management parameters need careful review against the observed tail risk. This historical data simply reflects the outcomes of the executed trades and does not constitute a guide for future directional positioning.
