A Deadly Chart Pattern Says SanDisk’s 47% Crash Isn’t Over

SanDisk (SNDK) stock has crashed 47% in a month, and the SanDisk stock price now clings to one last support line after a brutal memory sector selloff.

The fall flipped a euphoric rally into a rout. Even so, SanDisk still holds a year-to-date gain of about 362%, a reminder of how far and how fast this stock ran.

Memory Selloff Turns the Rally Into a Rout

SanDisk dropped 14% on Tuesday to close near $1,096, capping a 47% slide over one month. The move erased months of gains in a matter of weeks.

The trigger came from Asia. Memory chip stocks sank after South Korea’s SK Hynix posted quarterly results that missed forecasts, reviving fears that AI-driven demand is cooling. The weakness spread quickly to Micron, Western Digital, and SanDisk.

The same sector had rallied for months on SK Hynix and Samsung’s $950 billion AI chip deals, which makes the reversal sting harder. The charts now tell a darker story.

A Bearish Crossover Breaks the Uptrend

The technical damage runs deep. SanDisk’s 20-day Exponential Moving Average (EMA), a fast trend line that weights recent prices, crossed below the 50-day line. The stock has fallen about 35% since that bearish signal.

Price then sliced under the 100-day EMA, leaving only the 200-day line near $995 as support. Meanwhile, a head and shoulders pattern, a topping shape where a high peak sits between two lower ones, completed as its neckline broke yesterday.

Selling volume surged on the breakdown, which shows sellers remain in control. The pattern points to a further drop of roughly 39% from the neckline.

Institutions Sold Before the SNDK Price Fell

The big money moved early. Chaikin Money Flow (CMF), a gauge of institutional buying and selling pressure, weakened from May 8 even as SanDisk kept climbing. That gap warned the rally was running without real support.

CMF then crossed below zero on June 22, and the price rolled over soon after. It now reads negative 0.15, so the selling pressure has not eased.

Options Traders Turn Cautiously Optimistic

Some traders are betting the worst is over. The SNDK put-call ratio, which compares bearish put bets to bullish call bets, eased from 1.54 on July 22 to 1.02 by volume, a sign optimism is creeping back. Open interest still leans bearish, however.

Trader Optimism: Barchart

Analysts stay firmly bullish. SanDisk carries a Strong Buy from 17 analysts with an average SNDK price target near $2,053, led by Goldman Sachs at $2,200 and Bernstein at $3,000.

Still, cracks are forming. Wells Fargo and Argus moved to Hold, and Susquehanna trimmed its target from $3,250 to $3,050.

Around a month ago, a couple of hedge fund friends pitched me on $SNDK, $MU, $SKHY , and the rest of the memory names as their best ideas. The thesis was compelling, and the guys are very smart. Their main argument was simple: these companies were incredibly cheap. P/E of 10. P/E… https://t.co/8HjqBhChle pic.twitter.com/5AiRjjO5Sc

SanDisk Stock Price Levels to Watch

The SanDisk stock price now sits on a knife edge. It must hold the 0.618 Fibonacci level near $1,059 and the 200-day EMA at $995 to keep any recovery alive.

If those hold, SanDisk can aim for $1,303, then $1,453, and finally $1,697, the level that would reopen the path toward analyst targets. Earnings on August 5 are the next test.

SanDisk Price Analysis: TradingView

A clean break under $995 changes the picture, exposing $886 and then $665. So even as options traders turn hopeful, the broken pattern and negative money flow argue the fall may not be over. For now, $995 separates a fragile bounce from a far deeper collapse.
