Micron Technology Surges 7.55% to $150.57 Amid Bullish Momentum Signals

Candlestick Theory
Micron Technology's price action exhibits a robust bullish trend, with seven consecutive white candles culminating in a 7.55% surge on September 11, 2025. This sequence—marked by higher highs and higher lows—confirms strong upward momentum. The September 11 session recorded a long upper wick (high: $156.26, close: $150.57), signaling interim resistance near $156 and profit-taking pressure. Immediate support rests at the session low of $147.61, aligning with the prior day’s high of $142.24. A decisive close above $156 could trigger further upside, while failure to hold $147 may invite short-term consolidation.
Moving Average Theory
The moving averages reflect a powerful bullish alignment. The 50-day MA (∼$122.50), 100-day MA (∼$108.30), and 200-day MA (∼$95.60) are ascending in bullish sequence (short > medium > long-term). The current price ($150.57) trades substantially above all three, indicating strong trend sustainability. Notably, the 50-day MA has consistently acted as dynamic support during pullbacks (e.g., mid-August 2025). The widening gap between price and the 200-day MA highlights long-term strength but may also signal overextension if volatility contracts.
MACD & KDJ Indicators
The MACD (12,26,9) shows sustained bullish momentum with the histogram above zero but exhibits deceleration over the past three sessions—diverging from price highs. This suggests potential near-term consolidation despite the uptrend. Meanwhile, the KDJ oscillator (14,3,3) is deeply overbought: K (89), D (86), and J (95) all exceed 80. While such readings can persist in strong trends, the J-line’s parabolic rise hints at exhaustion. A bearish KDJ crossover (K below D) could foreshadow a pullback toward neutral levels (50 zone).
Bollinger Bands
Bollinger Bands (20-day) expanded sharply during the 27% seven-day rally, reflecting heightened volatility. The price pierced the upper band ($152) on September 11 but closed slightly below it, signaling a temporary overheating. The bands’ width has reached annual highs, often preceding consolidation. Support now converges near the middle band (20-day MA, ∼$132), while a sustained break below this level could trigger a mean-reversion test of the lower band ($120).
Volume-Price Relationship
Volume validates the rally’s legitimacy. Aggregate volume over the seven-day advance exceeded 180 million shares, peaking at 52.4 million shares (+7.55% day)—the highest since April 2025. This accumulation pattern, coupled with rising closes, signals institutional participation. However, the September 11 volume spike coinciding with a wick rejection at $156 raises caution; follow-through buying is essential to confirm breakout sustainability. Conversely, a decline on elevated volume could indicate distribution.
Relative Strength Index (RSI)
The 14-day RSI (75.8) resides near overbought territory but hasn’t breached 70 until the recent surge. While RSI readings >70 typically warn of overbought conditions, they can persist in strong trends. The current level suggests upside momentum remains intact but is approaching exhaustion. Divergence is absent (RSI aligns with new price highs), limiting immediate reversal signals. Traders should monitor for RSI rejection near 80—a level associated with prior intermediate tops in Q1 2025.
Fibonacci Retracement
Applying Fibonacci to the March-June 2025 decline (swing high: $156.26 on June 25, low: $82.62 on May 7), key retracement levels emerge: 61.8% ($132.50), 50% ($119.44), and 38.2% ($106.40). The recent rally surpassed the 100% extension level ($150), reaching $156.26. This aligns with the 127.2% external retracement ($154.50), serving as resistance. A pullback should test the 61.8%-76.4% zone ($132.50–$142.50) as primary support, coinciding with the 50-day MA and September 10 high—a critical confluence area.
Synthesis of Confluence and Divergence
Confluence: The MA alignment, volume-supported breakout, and Fibonacci extension cluster ($150–$156) reinforce a macro uptrend. However, bearish divergences are emerging: MACD momentum fading at new highs, extreme KDJ/RSI readings, and Bollinger Band expansion suggesting volatility exhaustion. These divergences advise caution for near-term entry but do not invalidate the bullish structure. Traders might expect consolidation between $147 (immediate support) and $156 (resistance), with a close below $147 potentially triggering a deeper retracement toward $132–$142. Long-term bias remains positive above the 200-day MA ($95.60), but tactical pullbacks appear increasingly probable.
