Observations from Outcomes
Reviewing the closed trades reveals a degree of volatility, as evidenced by the best gain (+28.27%) being substantially larger than the worst loss (-11.82%). The fact that 제넥신 (095700) appeared in both the notable wins and notable losses suggests that the asset exhibited significant intraday directional swings, which is a key pattern to observe when analyzing its underlying drivers. The losses incurred on DN오토모티브 (007340) and EMB (278990) highlight instances where the initial directional conviction did not hold through to the exit point 
.
Lessons from Underperformance
The trades that resulted in losses, such as those on DN오토모티브 (007340) and EMB (278990), suggest that momentum decay or sudden shifts in broader market sentiment can quickly erode gains. Specifically, the divergence between the average win size and the average loss size, while positive overall, indicates that the risk management around the losing trades needs careful review. The magnitude of the losses relative to the wins suggests that while the selection process is effective, the exit discipline during adverse moves requires continued attention
