Recap
The day’s closed trading activity showed a mixed outcome. Out of the 182 trades closed, the win rate registered at 17.6%. The average profit per winning trade was positive at +4.81%, contrasting with an average loss of -4.48% on losing trades. The overall expectancy for the closed set was negative at -2.84% per trade. Notable positive returns were observed in 네오이뮨텍 (950220) at +29.59%, 아난티 (025980) at +13.14%, and 소마젠 (950200) at +10.07%. Conversely, the losses were substantial, highlighted by 코미코 (183300) at -48.45%, DN오토모티브 (007340) at -10.15%, and EMB (278990) at -9.41%. 
Observations from Losses
The significant negative outcomes, particularly the -48.45% recorded on 코미코 (183300), suggest that the portfolio encountered instances where downside risk materialized sharply. These losses indicate that the market structure or specific stock dynamics on those days presented considerable headwinds that the executed trades could not absorb. The disparity between the best gain (+29.59%) and the worst loss (-48.45%) points to a high degree of volatility being present across the sampled names. 
For Next Time
The current performance metrics, particularly the low profit factor of 0.23, suggest that the magnitude of losses is currently outweighing the gains realized. The data reflects a challenging environment where capital preservation proved difficult across multiple entries. The observed results emphasize the need for a cautious approach when navigating periods where the overall trend appears subdued.
