Recap
The trading activity for the period saw 154 closed trades, resulting in a win rate of 41.6%. The overall expectancy was negative at -0.58% per trade, with a profit factor of 0.64. The average winning trade generated a gain of 2.50%, while the average losing trade incurred a loss of 2.77%. Notable positive outcomes included 원익홀딩스 (+12.36%) and 주성엔지니어링 (+8.57%). Conversely, notable losses were recorded in 코스맥스 (-4.93%), 로보티즈 (-4.81%), and OCI홀딩스 (-4.67%). 
Observations on Outcomes
The spread between the average win and average loss suggests that the magnitude of losses has been slightly outpacing the gains realized across the closed positions. The best single performance, 원익홀딩스, provided a significant positive deviation, but this was counterbalanced by several trades that settled into moderate losses. The pattern indicates that while some directional calls captured substantial upside, the frequency and depth of the smaller losses kept the aggregate performance subdued.
Lessons from Losses
The trades that concluded with losses, such as those in 코스맥스 and 로보티즈, highlight instances where the initial momentum failed to sustain or where market resistance proved stronger than anticipated. These outcomes suggest that relying on initial breakouts without confirming broader sector support can lead to rapid retracements. The negative expectancy points to a structural drag across the executed trades, indicating that the prevailing market conditions presented headwinds that were not fully accounted for in the trade execution profile. 
For Next Time
The data reflects a period where the cost basis of losses was substantial relative to the gains. The observed performance suggests that the market environment has been challenging, absorbing gains and leading to several instances of profit-taking that materialized as losses on the executed trades.
