Recap
The day’s closed trading activity showed a mixed performance. Out of 263 trades, the win rate settled at 47.5%. The average profitability per trade was negative at -1.05%, with the profit factor registering at 0.55. Wins were generally positive, with the average gain at +2.65%, contrasting with an average loss of -4.39%. Notable positive outcomes included significant gains in 에프에스티 (036810) and 이오테크닉스 (039030). Conversely, notable losses were recorded in 아이티센글로벌 (124500) and 와이씨 (232140), which represented the larger drawdowns for the session. 
Observations on Drawdowns
The larger losses observed today, such as those in 아이티센글로벌 (124500) and 오름테라퓨틱 (475830), suggest that when the market sentiment shifts against established positions, the downside can be pronounced. The magnitude of the average loss relative to the average win indicates that the risk taken on losing trades has been substantial. 
For Next Time
The results confirm that the current trading regime presents challenges, as evidenced by the negative expectancy. The spread between the best gain (+11.03%) and the worst loss (-9.05%) highlights the potential for high volatility swings within the KOSPI space. A focus on managing the frequency and size of the negative outcomes appears warranted given the current flow dynamics.
