Recap
The trading session saw 153 closed trades, resulting in a win rate of 45.8%. The overall expectancy was positive at +0.10% per trade, supported by an average win of +3.43% against an average loss of -2.71%. The performance highlights notable gains, such as the 18.49% appreciation on 심텍 (222800) and the 8.99% gain on 한전기술 (052690) 
. Conversely, the session also recorded notable drawdowns, including the -5.21% on 한전기술 (052690) and the -4.45% on 기가비스 (420770).
Observations
The spread between the average winning percentage and the average losing percentage suggests that while the positive outcomes were substantial, the losses were also significant enough to temper the overall edge. The fact that some names appeared in both notable wins and notable losses, such as 한전기술 (052690) and 기가비스 (420770), indicates that the underlying market dynamics for these specific names presented considerable volatility throughout the period. It is encouraging to see the positive profit factor of 1.07, suggesting that the winning trades slightly outweighed the losing ones in terms of total realized profit.
For Next Time
The instances where trades resulted in losses, particularly those involving names that showed strong gains earlier in the cycle, suggest a need to pay closer attention to the immediate reversal signals following sharp upward movements. The divergence between the best outcome (+18.49%) and the worst outcome (-5.21%) reminds one that market conviction can shift rapidly, even within the same sector or stock. It is simply a matter of observing the full spectrum of realized outcomes
