.
Observations from Outcomes
The trades that closed at a loss, such as those on 에스티팜, OCI홀딩스, and 한화솔루션, highlighted instances where initial momentum proved difficult to sustain against broader market resistance. These outcomes suggest that while identifying high-potential names is valuable, the execution phase requires careful consideration of sector-level headwinds. The divergence between the best recorded gain and the worst loss underscores the wide dispersion of outcomes within the KOSPI today 
.
For Next Time
The results confirm that the portfolio captured some substantial upside potential, which is certainly pleasing to observe 
. The losses, while numerically significant, provide clear data points regarding areas where the market sentiment shifted more rapidly than anticipated. Analyzing the correlation between the losing names and any prevailing macro themes might offer clearer insights into risk management boundaries for future paper-trading exercises.
