Recap
The day’s closed trading activity shows a challenging pattern. Out of 225 trades closed, the win rate registered at 25.3%. The overall expectancy was negative at -2.56% per trade. The profit factor of 0.24 suggests that realized gains have been significantly outweighed by losses. The average winning trade yielded a gain of +3.15%, while the average losing trade resulted in a loss of -4.49%. Notable positive outcomes included gains on Hyundai Engineering & Construction (000720) at +10.11% and Samsung E&A (028050) at +6.94%. Conversely, significant drawdowns were observed on Hanmi Semiconductor (042700) at -10.16%, SK Hynix (000660) at -10.14%, and HD Hyundai Electric (267260) at -9.83%. 
Observations
The performance metrics indicate that the magnitude of losses has been disproportionately large relative to the gains realized across the closed set. The notable losses, particularly those involving major semiconductor and heavy industry names, suggest that when directional conviction proved incorrect, the resulting drawdowns were substantial. This pattern suggests that the market environment has presented significant headwinds, leading to outcomes where the risk taken on the downside has been costly. 
For Next Time
The significant negative expectancy, despite some large positive captures, points to a structural issue in the trade selection or sizing relative to the prevailing market conditions. The depth of the losses recorded on key names suggests that the market structure may be favoring downward momentum or exhibiting high volatility spikes that are difficult to navigate without significant capital erosion.
