Record revenue and buybacks drive institutional inflows after index news

SanDisk reported record fourth-quarter revenue of $8.97 billion, driven by increased data center business and backed by $93.9 billion in long-term supply contracts stretching to 2028. The company’s share repurchase authorization was raised to $15.5 billion, and SanDisk’s market capitalization now stands at approximately $273 billion. Institutional buyers have recently increased holdings, following the announcement of S&P 100 index inclusion.

Anton Kharitonov, expert at Traders Union, sees SanDisk’s latest rally as fueled more by index inclusion hype than by underlying fundamentals. Strong technicals and institutional buying point to sustained demand, but elevated valuation and overbought signals raise caution. He believes that momentum could quickly reverse if expectations fade or broader sentiment shifts. The concentration of recent gains suggests absence of steady, organic support. "Despite current strength, I warn traders not to chase the rally blindly — a correction toward $1,683 remains very possible if sentiment turns."

Viktoras Karapetjanc, expert at Traders Union, highlights SanDisk’s robust positioning after record revenue and an expanded share repurchase plan. He finds the company’s long-term supply contracts and institutional accumulation especially promising for ongoing growth. The recent inclusion in the S&P 100 has sparked renewed investor confidence and liquidity inflows. "I see the bullish structure as intact — further upside above $1,908 is likely as the market offers multiple setups for growth-oriented traders."

Jainam Mehta, market strategist, notes that SanDisk’s breakout is supported by technical momentum but warns that overbought indicators may limit immediate upside. He emphasizes the importance of the $1,908 resistance, viewing a close above this level as a trigger for tactical longs. Mehta also flags potential for increased volatility if the price drops below $1,683. "I am watching for either a momentum-driven breakout or a reversal setup near key bands — traders should be prepared for both scenarios."

Uptrend solidifies with all-timeframe momentum and overbought signals

SanDisk is trading above all key moving averages, with the current price at $1,795—firmly above the 20-day ($1,529), 50-day ($1,550), and 200-day ($1,003) signaling strong bullish momentum across all timeframes. The 50-day average remains well above the 200-day, underscoring the uptrend. Immediate resistance is at $1,908, with support at $1,788. Momentum indicators are mostly bullish: MACD supports buying strength, the Relative Strength Index (RSI) is elevated at 61.24, Stochastic RSI is at 100 and the Commodity Channel Index (CCI) at 117.41, both highlighting overbought conditions. Bull/Bear Power (BBP) at 183.86 and a positive Awesome Oscillator reinforce this buyer dominance. The stock gained $57.02 or 3.28% after an upside gap of about 2.02%, closing near the session high. Intraday volatility was 2.20%, reflecting sustained and persistent demand throughout the day.

Earlier, analysts noted that SanDisk was demonstrating broad-based bullish momentum, supported by strong trend alignment across key technical indicators. With the company's S&P 100 inclusion now reinforcing these bullish signals, traders should monitor $1,908 as the pivotal resistance level for confirmation of continued upside.
