Micron Technology (MU) Plunges 3.8% Amid Earnings Optimism and Sector Volatility – What’s Fueling the Selloff?

Summary
• Micron Technology (MU) trades at $183.67, down 3.8% from its $190.96 previous close
• Intraday range spans $183.24 to $195.2999, reflecting sharp volatility
• Morgan Stanley upgrades MU on 100% 2026 earnings growth projections, yet shares falter
• Sector-wide U.S. chip tariff concerns and geopolitical tensions amplify selloff

Micron Technology’s (MU) 3.8% intraday decline has ignited a firestorm of speculation, despite bullish analyst upgrades and robust earnings projections. The stock’s sharp pullback, amid a broader semiconductor sector slump, underscores a tug-of-war between short-term macro risks and long-term growth optimism. With Morgan Stanley highlighting DRAM pricing momentum and multiple quarters of upward revisions, investors are left deciphering whether this is a buying opportunity or a warning sign in a volatile market.

Sector-Wide Volatility and U.S. Tariff Fears Overshadow Earnings Optimism
Micron’s selloff is part of a broader semiconductor sector correction driven by U.S. chip tariff anxieties and geopolitical tensions. Despite Morgan Stanley’s upgrade citing 100% 2026 earnings growth and strong DRAM pricing, the market is pricing in near-term risks. Recent news of U.S. tariffs on South Korean semiconductors and China’s push to triple AI chip output have amplified sector-wide jitters. Additionally, Intel’s 10% government stake and Trump-era policy uncertainty have created a toxic mix, causing investors to rotate out of high-growth tech names like MU into defensive assets.

Semiconductor Sector Under Pressure as Tariff Fears Intensify
The semiconductor sector, as represented by the XLK ETF, has mirrored MU’s decline, with Intel (INTC) down 0.48% and TSMC (TSM) underperforming. This suggests the selloff is not isolated to Micron but reflects a broader risk-off sentiment. U.S. policy shifts, including potential 100% tariffs on South Korean chips and revenue-sharing deals with AMD and Nvidia, have created a regulatory overhang. Meanwhile, China’s aggressive AI chip localization efforts and India’s $550M semiconductor expansion further complicate the global supply chain outlook.

Options Playbook: Leveraged Puts and Covered Calls in a Volatile MU Landscape
• 200-day average: $107.02 (far below current price)
• RSI: 75.26 (overbought territory)
• MACD: 13.9996 (bullish divergence)
• Bollinger Bands: Upper $192.24, Middle $163.70, Lower $135.16 (price near upper band)

Micron’s technicals suggest a volatile setup with overbought RSI and a MACD above zero, but the 200-day average is a distant support. Short-term traders should watch the $180 level, with a breakdown triggering a test of the $170 support. For leveraged exposure, consider the MU20251017P180 put option (strike $180, expiration 10/17) and MU20251017C180 call option (strike $180, expiration 10/17).

Top Option 1: MU20251017P180 (Put)
• Code: MU20251017P180
• Type: Put
• Strike Price: $180

• Theta: -0.093164 (moderate time decay)
• Gamma: 0.018179 (responsive to price swings)
• Turnover: 1.345M (high liquidity)
This put option offers a 33.5% leverage ratio and high implied volatility, ideal for a bearish move. A 5% downside to $174.50 would yield a $5.50 payoff, making it a high-reward play if the $180 level breaks.

Top Option 2: MU20251017C180 (Call)

Trading Hook: Aggressive bulls may consider MU20251017C180 into a bounce above $180, while bears should target MU20251017P180 on a breakdown below $180.

Act Now: MU at Pivotal Crossroads – Short-Term Volatility or Long-Term Opportunity?
Micron’s 3.8% selloff reflects a critical juncture where macro risks clash with long-term growth fundamentals. While U.S. tariff fears and sector-wide jitters dominate the near term, Morgan Stanley’s 100% 2026 earnings growth projection and DRAM pricing momentum suggest the sell-off could be overdone. Investors should monitor the $180 support level and the broader semiconductor ETF (XLK) for sector cues. With Intel (INTC) down 0.48%, the sector’s direction will likely dictate MU’s path. Act now: Short-term traders should target MU20251017P180 on a breakdown below $180, while long-term bulls may accumulate dips above $180, leveraging the 100% earnings growth narrative.
