Micron Technology Plunges 3.75% Intraday – What’s Behind the Sudden Sell-Off?

Summary
• Micron Technology (MU) drops 3.75% to $108.98, breaching intraday low of $108.13
• Leveraged ETF Direxion Daily MU Bull 2X Shares (MUU) plummets 7.35%, amplifying bearish sentiment
• Sector peers like Intel (INTC) trail with -0.26% decline, signaling broader tech caution
• The semiconductor sector faces regulatory scrutiny and AI-driven valuation shifts as MU’s sharp drop raises questions about near-term resilience.

Sector-Wide Profit-Taking and Regulatory Uncertainty
Micron’s intraday plunge stems from sector-wide profit-taking following recent AI-driven optimism and regulatory concerns over global chip trade policies. While the stock remains within a long-term range bound by $61.54 and $129.85, short-term bearish momentum is fueled by elevated implied volatility (51.49% for August 1 puts) and bearish technical indicators like RSI at 34.18 (oversold) and a negative MACD histogram (-2.13). The lack of immediate company-specific news suggests broader macroeconomic and geopolitical factors, such as U.S.-China trade tensions and Arm IPO dynamics, are driving the sell-off.

Semiconductor Sector Mixed as Intel Trails Behind
The semiconductor sector remains fragmented, with Intel (INTC) down 0.26% despite broader AI enthusiasm. TSMC’s $100M Arm investment and GlobalFoundries’ Singapore expansion hint at sector resilience, but regulatory headwinds and valuation corrections are evident. Micron’s sharp drop contrasts with Tokyo Electron’s market cap surge, highlighting divergent investor sentiment across chip subsectors.

Backtest Micron Technology Stock Performance
The backtest of MU's performance after a -4% intraday plunge shows favorable short-to-medium-term gains. The 3-day win rate is 52.45%, the 10-day win rate is 55.77%, and the 30-day win rate is 65.24%, indicating a higher probability of positive returns in the immediate aftermath of the plunge. The maximum return during the backtest period was 9.30%, which occurred on day 59, suggesting that MU can recover significantly from such events.

Position for the Semiconductor Sector's Volatility – Act Now or Watch the 104.5 Support
Micron’s sharp drop reflects broader sector fragility amid regulatory and valuation pressures. The 200-day average at $98.70 and 30-day support at $119.78 suggest a critical test at $104.50, below which further declines toward $97.58 (200D support) are possible. Intel’s -0.26% decline underscores sector-wide caution. Aggressive bears should target MU20250801P104 for $104 breakdowns, while conservative investors watch the 52W low at $61.54 for long-term entry cues. Watch for $104.50 breakdown or sector regulatory updates.
