SanDisk (SNDK) stock has staged an impressive rally in recent weeks, breaking above multiple key resistance levels and accelerating into a parabolic uptrend. With bullish momentum continuing to build, investors are now watching whether the stock can sustain its breakout or if a healthy correction is approaching.

SanDisk Stock Surged an Astonishing 8,343% in Just 14 Months

SanDisk (SNDK) has delivered an extraordinary rally, surging more than 8,343% in less than 14 months. The parabolic advance propelled the stock to a new all-time high of $2,354 this month before entering a modest corrective phase.

Despite the recent pullback, the long-term bullish structure remains intact. The first major Fibonacci support sits at $1,466, followed by the critical golden ratio Fibonacci support at $850.

As long as SanDisk holds above the golden ratio support at $850, the broader uptrend remains structurally bullish. A sustained break below this level, however, would significantly weaken the long-term technical outlook and increase the probability of a deeper correction.

Bearish Divergence Forms on the Weekly RSI

On the weekly chart, SanDisk has started to form a bearish divergence on the RSI, signaling weakening momentum despite the recent uptrend. In line with this development, the stock has already corrected by 21% this week and could extend its decline toward the 0.382 Fibonacci support level at $1,466. If this support fails to hold, the next major downside targets are the golden ratio support at $850 and the 50-week EMA at $767.

Meanwhile, the MACD histogram has continued to tick lower this week, reflecting fading bullish momentum. However, the MACD lines remain bullishly crossed, indicating that the broader uptrend has not yet been invalidated.

Predominantly Bullish Signals on the Daily Chart for SanDisk Stock

On the daily chart, the indicators continue to paint a predominantly bullish picture. The MACD lines remain bullishly crossed, while the EMAs maintain a golden crossover, confirming the short- to medium-term uptrend. Meanwhile, the RSI sits in neutral territory, leaving room for further price movement in either direction. However, the MACD histogram has started to tick lower today, signaling that bullish momentum is beginning to weaken.

If SanDisk extends its corrective move, the next major Fibonacci support level sits around 27% below the current price. Additionally, the 50-day EMA provides an important support zone at $1,578, which could help cushion any further downside.

Immediate Support at the 50-4H EMA at $1,848

On the 4-hour chart, the EMAs continue to display a golden crossover, confirming the short-term trend remains bullish. However, the MACD lines have crossed bearishly, while the MACD histogram has started to tick lower, signaling increasing downside momentum. Meanwhile, the RSI remains in neutral territory, leaving room for further price movement in either direction.

If SanDisk (SNDK) extends its corrective phase, the first major support level lies at the 50-period EMA on the 4-hour chart at $1,848. Should this level fail to hold, the next significant support awaits at the 0.382 Fibonacci retracement level at $1,466.

SanDisk (SNDK) Price Prediction: Summary

SanDisk remains in a strong long-term uptrend despite entering a corrective phase after its parabolic rally. While the daily chart continues to favor the bulls, weakening momentum on the weekly timeframe and a bearish RSI divergence suggest the correction could extend further. The first major support lies at the 50-4H EMA at $1,848, followed by the 50-day EMA at $1,578 and the 0.382 Fibonacci support at $1,466. If this level fails, the next key downside targets are the golden ratio support at $850 and the 50-week EMA at $767. As long as SanDisk holds above $850, the broader bullish market structure remains intact.
