Recap
The day’s closed trading activity reflects a mixed outcome. Out of the 208 trades concluded, the win rate settled at 40.9%. The average profit realized per winning trade was +3.11%, contrasting with an average loss of -3.49% on losing trades. The overall expectancy for the closed trades was negative at -0.79% per trade. Notable positive returns were observed in 티에스이 (131290) at +12.35%, 티씨케이 (064760) at +11.69%, and HD현대마린솔루션 (443060) at +10.79%. Conversely, losses were recorded in 티에스이 (131290) at -5.67%, 보로노이 (310210) at -5.52%, and 산일전기 (062040) at -5.49%. 
Observations
The disparity between the average win size and the average loss size suggests that while profitable trades achieved significant gains, the frequency and magnitude of losses contributed to the negative expectancy. The performance metrics, particularly the profit factor of 0.62, indicate that the realized gains were not sufficiently compensating for the incurred losses over the period. 
Lessons from Outcomes
The trades that resulted in losses, such as those in 티에스이 (131290) and 보로노이 (310210), highlighted instances where initial momentum or perceived strength did not translate into sustained upward movement. The losses were relatively consistent in magnitude, suggesting that the market resistance or underlying selling pressure was persistent across different sectors. 
For Next Time
The data shows that the best recorded gain (+12.35%) and the worst recorded loss (-5.67%) occurred within the same symbol, 티에스이 (131290). This juxtaposition suggests that individual stock performance can exhibit high volatility within a single trading session. The overall picture remains subdued, pointing toward caution in the current KOSPI environment.
