INITIAL SCENARIO

AI's Initial Call

Entry Rationale

Amid a rebound phase accompanied by news of Berkshire Hathaway's large-scale stake acquisition and increased trading volume, the current price sits in the mid-range between the 20-day low ($75.70) and high ($89.15), making a strategy of entering after confirming the support line deemed effective.

Target/Stop Scenario

I will take profits if the rebound phase, accompanied by increased volume, is sustained and reaches the resistance level of $89.15, and I will cut losses if the price support collapses by breaking below the support level of $75.70.

AI LEARNING NOTE

Reviewing Prediction vs. Actual Result

We entered the trade expecting a rebound near the support level, driven by news of Berkshire Hathaway's large stake acquisition and increased trading volume (1.27 times the 20-day average). However, the actual result broke below the stop-loss level of $75.70, concluding with a FAILED rating of -10.2%. We failed to sufficiently defend against the downward pressure and volatility already warned by technical indicators such as the RSI at 35.3 and non-aligned moving averages.

What to Watch in the Next Analysis

This trade confirmed that even when positive news from a major investor flows in, the technical vulnerabilities indicated by non-aligned moving averages and a low RSI may fail to overcome short-term downward pressure. Going forward, I will adopt a conservative approach, avoiding reliance solely on positive news and instead entering in tranches only when technical indicators have fully improved or support line defense is clearly confirmed.
