SanDisk stock: here's what options data reveal ahead of Q3 earnings

SanDisk stock (NASDAQ: SNDK) heads into Thursday’s Q3 report with traders braced for a violent move, not a routine earnings reaction.

The stock closed at $1,064.21 on Wednesday after falling 6.34% in the previous session, even as the stock remained one of 2026’s biggest winners.

SanDisk is set to report fiscal third-quarter results after the close on Thursday, and the options market is pricing in a swing of roughly 21% in either direction.

That is a large move for any megacap-style name, and it underscores how much is riding on this one print.

What options traders are actually pricing in

The key point is that options are not forecasting a direction here; they are pricing the size of the move.

TipRanks says SanDisk options imply a 21.11% reaction to earnings, while Barchart shows implied volatility at 112.97% and a put/call volume ratio of 1.37, with puts ahead of calls in the session data.

TipRanks’ separate Fly feed also described the tape as mixed, with 91,000 contracts traded, a put/call ratio of 1.11 and IV30 near 115.91.

Put simply, traders are paying up for protection and exposure, but they are not agreeing on whether the next move is up or down.

That matters because an implied move of about 21% is a statement about uncertainty.

In options terms, the market is signaling that an at-the-money straddle could reprice for a very large post-earnings range.

Barchart’s own explanation of expected move ties the figure to the ATM straddle, which is why the message from the options screen is about range rather than direction.

Numbers behind the setup

Fundamentally, SanDisk stock is walking into the report with a very high bar.

The company told investors in late January that third-quarter revenue should come in between USD 4.4 billion (approx. $6.4 billion) and USD 4.8 billion (approx. $7 billion), with non-GAAP EPS of $12 to $14.

Wall Street’s latest estimate is even higher, with TipRanks citing revenue of about USD 4.7 billion (approx. $6.8 billion) and EPS of $14.54.

The bull case is still built on AI-related storage demand.

In SanDisk’s second quarter, datacenter revenue rose to USD 440 million (approx. $641.2 million), up 64% sequentially and 76% from a year earlier.

Morgan Stanley leaned into that story this week, lifting its price target to $1,100 from $690 and arguing that its 2026 earnings view sits about 65% above consensus.

SanDisk stock is up about 322% year to date.

The risk the market is not talking about

The danger is that a stock this extended can move both ways at speed.

SanDisk’s beta is 5.04, which is a reminder that the name tends to amplify broad market moves rather than absorb them.

That is one reason the April 28 selloff drew attention, as the stock can give back a large amount of ground quickly when momentum traders step aside.

The official price history shows the shares traded as high as $1,070.20 on April 27 before closing at $1,002.35 the next day.

Morgan Stanley’s note highlighted continued pricing strength in NAND, but it also pointed to the difficulty of forecasting mix and the importance of durable demand.
