• The stock has slipped below its 52-week average of $83.21x PE, raising concerns over near-term earnings expectations.
• VanEck Fabless Semiconductor ETF (SMHX) follows the downward spiral, down 2.88%, as leveraged semiconductors ETFs falter.

Monolithic Power (MPWR) has seen a dramatic drop in value, with its price plummeting nearly 3.6% in a single trading day. The stock has hit its intraday low of $1,052.57 after opening above $1,094 and swinging through a tight range. This move has drawn attention not only to the stock but to the broader semiconductor sector, as leveraged ETFs and sector peers also trend lower.

Technical Weakness and Investor Sentiment Drag Shares Downward
The intraday drop in Monolithic Power appears to stem from a combination of technical indicators and deteriorating investor sentiment. Despite a short-term bullish candlestick pattern like the bullish engulfing, the RSI has dipped below 50 to 42.8, signaling a shift in momentum. Additionally, the MACD (-15.9) has crossed below its signal line (-12.9), confirming a bearish crossover. The stock has also broken below its 30-day moving average at $1,132.08, which acts as a key support-turned-resistance level. Traders are now watching closely to see whether the stock can reclaim these levels or continue its downward momentum into lower support at $952.48.

Semiconductor Sector Under Pressure with Intel Leading the Sell-Off
The semiconductor sector is in the crosshairs of today’s decline, with Intel (INTC) falling hard by -5.23%, setting a tone for the entire sector. Monolithic Power, while not the worst performer, is tracking closely with sector ETFs like iShares Semiconductor ETF (SOXX) down -3.35%. This synchronized drop suggests broader market concerns over macroeconomic headwinds or sector-specific news. The weakness in INTC could be signaling a broader correction as investors reprice expectations for global chip demand.

Positioning for a Volatile Semiconductor Landscape: ETFs and Technical Reads
• 30-day MA: 1132.08 (below current price)
• RSI: 42.78 (bearish momentum)
• MACD: -15.9 (crossed below signal line)
• Bollinger Bands: 980.16 – 1236.61 (stock currently near lower band)
• Leveraged ETF: SOXX (SOXX) down -3.35%

Monolithic Power is showing bearish technical signals, with price breaking below its 30-day moving average and approaching the lower Bollinger Band at $980.16. A close below $1,052.57 could trigger a retest of the 200-day moving average at $924.82, a critical level for medium-term traders. Given the volatility, investors may consider hedging long positions or shorting the leveraged ETF SOXX (SOXX), currently at $328.82 with a -3.35% intraday move. Traders should watch for a break below $1,052.57 to confirm a short-term bear trend and consider bearish options if they open up in the near future.

Unfortunately, the options chain is missing, so no options-based strategies are currently executable. However, the technical setup is clear: a break below $1,052.57 could accelerate the sell-off, making SOXX a strategic short play.

Backtest Monolithic Power Stock Performance
The performance of MPWR (Morgan Stanley Capital International) after a -4% intraday plunge from 2022 to now has shown positive short-to-medium-term gains. The backtest data indicates that the 3-day win rate is 60.08%, the 10-day win rate is 58.08%, and the 30-day win rate is 63.67%.

MPWR Faces Near-Term Breakdown: What to Watch for in the Coming Sessions
Monolithic Power is showing early signs of a near-term breakdown, with key technical indicators confirming a shift in momentum and the stock now hovering near its lower Bollinger Band. The broader semiconductor sector is also in retreat, led by Intel’s -5.23% drop. Investors should be alert for a close below $1,052.57 and a potential test of the $952.48 level. Given the sector’s vulnerability and the current bearish setup, short-side exposure via leveraged ETFs like SOXX (SOXX) could be a strategic play. A move below $1,052.57 would confirm a new short-term bear trend and open the door for more aggressive positioning.
