Monolithic Power Systems Jumps 5.36% on Bullish Technical Signals

Comprehensive Technical Analysis of Monolithic Power Systems (MPWR)
Monolithic Power Systems advanced 5.36% in the latest session, closing at $968.10 on significant volume, signaling renewed bullish momentum. The following analysis employs multiple technical frameworks using approximately one year of historical price data.
Candlestick Theory
Recent price action reveals constructive patterns. The session ending 2025-09-30 formed a bullish engulfing candle, suggesting rejection of lower prices near $894.38 support. A hammer candle emerged on 2025-10-03 (low: $916.80, close: $918.83), indicating potential reversal pressure. Current consolidation between $915 support (tested multiple times in early October) and resistance near $986.63 (recent high) is notable. A decisive break above $986.63 would signal continuation, while failure to hold $915 may trigger deeper retracement.
Moving Average Theory
The 50-day moving average (~$880), 100-day MA (~$800), and 200-day MA (~$740) maintain upward slopes, confirming the primary bullish trend. The price currently trades above all key moving averages, with the 50-day acting as dynamic support during the September pullback. The golden cross (50-day above 200-day) established in early 2025 remains intact, reinforcing the long-term uptrend. However, the gap between the price and the 50-day MA widened notably on 2025-10-06, suggesting potential near-term consolidation.
MACD & KDJ Indicators
The MACD histogram transitioned into positive territory on 2025-10-06, signaling a return of bullish momentum as the MACD line crossed above the signal line. KDJ shows the %K line crossed above the %D line from oversold territory (<20) in late September, generating a buy signal that preceded the recent rebound. Both indicators now suggest upward momentum, though KDJ's %K near 75 approaches overbought territory, warranting vigilance for near-term exhaustion.
Bollinger Bands
Bands contracted significantly in September, reflecting reduced volatility and consolidation between $890 and $930. The sharp expansion on 2025-10-06, with price closing near the upper band (~$974), signals a volatility breakout and potential continuation of the bullish impulse. Sustained trading near the upper band strengthens the uptrend case, while a move back towards the middle band (~$920) might indicate consolidation.
Volume-Price Relationship
The recent 5.36% surge on 2025-10-06 occurred on significantly elevated volume (647,127 shares vs. ~420k prior session), providing strong confirmation for the breakout. Throughout the September pullback, volume generally declined, suggesting a lack of strong conviction behind the selling. Notably, significant upside moves (e.g., 2025-08-04: +5.73%, 2025-09-12: +11.20%) consistently occurred on high volume, validating bullish advances. Volume support remains a key pillar of the uptrend.
Relative Strength Index (RSI)
The 14-day RSI currently reads approximately 62, climbing from oversold levels near 45 in late September but remaining below the overbought threshold of 70. This positioning suggests room for further upside before reaching overbought conditions. Crucially, no significant bearish divergence formed during the September dip; the RSI's trough corresponded with the price low near $834.14, supporting the integrity of the uptrend. The RSI indicates recovering strength without immediate warning signals.
Fibonacci Retracement
Applying Fibonacci retracement to the significant upswing from the Aug 25 low of $820.74 (2025-08-21) to the Oct 06 high of $986.63 reveals key levels. The 38.2% retracement sits at approximately $915, aligning perfectly with recent support. The 50% level near $904 and 61.8% level near $892 provided secondary support during pullbacks. The recent bounce from $915 validates this Fibonacci support zone. Projection towards the 127.2% extension (~$1045) may be considered if the price clears the $986 resistance convincingly.
Confluence & Divergence
Key confluence exists at the $915 zone, where significant price support, the 38.2% Fibonacci retracement, and the lower Bollinger Band (~$910 during consolidation) converge. The breakout on high volume, supported by bullish MACD and KDJ crossovers, strengthens the bullish case. No major divergences are presently evident across momentum oscillators relative to price action. However, proximity to psychological resistance at $1000 and KDJ approaching overbought levels suggests potential for near-term consolidation or pullback despite the positive confluence. Overall, the technical structure favors the bullish trend continuing after potential consolidation.
