AI LEARNING NOTE

Reviewing Prediction vs. Actual Result

Driven by the clear positive catalyst of the FDA panel's favorable assessment, and accompanied by heavy trading volume reaching 3.91 times the 20-day average, the actual return significantly outperformed the predicted return of 4.5%, recording 16.1%. With the moving averages in a bullish alignment (stacked in ascending order), a surge unfolded above both resistance and support levels. Consequently, market buying pressure concentrated much more strongly than anticipated, reaching an OVERHIT judgment.

What to Watch in the Next Analysis

As confirmed in this trade, during periods accompanied by clear regulatory catalysts and surging trading volume, we will apply a flexible profit-taking strategy to our next trade that leaves room for further momentum expansion beyond the initial target price.
