Recap
The day’s closed activity reflects a challenging pattern of outcomes. With a win rate near 30%, the overall expectancy for the closed trades was negative at -0.73% per trade. The performance metrics indicate that the average winning trade (+1.55%) was not sufficient to offset the average losing trade (-1.69%). Notable positive outcomes included gains in SNDK, WDC, and COHR, which provided some positive deviation from the mean. Conversely, losses were recorded in ZTS, YUM, and DPZ, demonstrating that even strong performers can be offset by deeper drawdowns. 
Observations on Performance
The disparity between the average win and average loss suggests that the magnitude of losses is currently outweighing the gains, despite achieving several profitable trades. The best recorded gain of +8.66% contrasts with the worst loss of -4.84%. This spread highlights the sensitivity of the cumulative result to the size and frequency of the negative deviations observed. 
Lessons from Losses
The trades that concluded at a loss, such as those in ZTS, YUM, and DPZ, point to an area where the market structure appears resistant to the initial directional bias. These instances suggest that when the initial thesis encounters significant selling pressure, the resulting drawdown can be substantial, eroding the gains from earlier, more favorable trades. 
For Next Time
The aggregate results suggest that the current environment is characterized by a negative expected value across the closed set of trades. The data emphasizes that the risk profile, as evidenced by the loss metrics, requires careful consideration against the realized gains. This is purely a review of historical trade outcomes and does not constitute investment guidance.
