Shares of Marvell (MRVL) are surging, earning praise from Wall Street after demonstrating a robust earnings outlook and a diversified customer and product mix.

INITIAL SCENARIO

AI's Initial Call

Entry Rationale

Wall Street's positive evaluation of Marble's diversified product mix and solid performance continues, but the current price has exceeded the 20-day resistance level ($280.00) and the RSI has entered the overheated zone at 81.5, so rather than immediate catch-up buying, we need to wait for a correction. Therefore, rather than entering urgently, I will approach cautiously from a split approach perspective around the support level ($213.63).

Target/Stop Scenario

As the current RSI is in the overbought zone, rather than blindly chasing the rally without conditions, I will approach the stock in installments if it pulls back toward the support level around $213.63 in preparation for a correction, and ultimately consider taking profit when it reaches the resistance level of $280.00.

AI LEARNING NOTE

Reviewing Prediction vs. Actual Result

At the time of prediction, the RSI was at 81.5, entering an overbought zone. Although a phased approach near the support line ($213.63) was considered in preparation for a correction, the actual result was recorded as a -12.1% FAILED (failure to reach the stop-loss line). While we recognized the high price level exceeding the 20-day resistance line ($280.00) and the overheated indicators, maintaining a conservative perspective, it is assessed that amid downward pressure following the short-term surge, the actual share price fell much deeper than the expected correction range, thereby breaching the stop-loss criteria.

What to Watch in the Next Analysis

This trade confirmed that in extreme overbought zones where the RSI exceeds 80, any chase-buying or hasty entry must be thoroughly avoided, regardless of accompanying positive earnings news. Moving forward, I will more strictly apply a strategy of waiting near support levels upon entering overbought zones, and manage risk by adjusting the scale-in buying ratio more conservatively in highly volatile periods.
