After A 6,000% Melt-Up, SanDisk Just Found Out Gravity Still Exists

The best-performing stock in the S&P 500 this year has given back a quarter of its value in four sessions.

SanDisk Corp. (NASDAQ: SNDK ) is down 24.8% week-to-Thursday, on track for its worst weekly performance since March 2025.

No warning.

No bad news.

Just the bill coming due.

The stock now trades nearly 39% below the record it set in June, a drawdown that would qualify as a crisis in almost any other name.

For SanDisk, it barely dents the chart.

The Rally That Made The Fall Inevitable Between June 2025 and June 2026, the stock climbed more than 6,000%.

Read that again.

A NAND flash memory maker — the company that puts storage chips inside phones, laptops and data centers — went from a forgotten spin-off to a $213 billion company in twelve months.

Moves like that do not correct politely.

The weekly chart shows what the ride actually looked like.

The stock has been running at a velocity that leaves no cushion underneath it, When a stock goes vertical, every buyer above a certain point is sitting on a profit and nothing else.

There is no long-term holder base to absorb selling.

Once the first wave decides to take money off the table, there is nobody underneath.

Investors who bought the melt-up were never buying SanDisk’s earnings.

They were buying momentum.

Momentum is now selling itself back to them.

Nothing Broke, According to Wall Street It is worth being clear about what has not happened.

SanDisk has not warned.

It has not cut guidance.

The company is not scheduled to report again until Wednesday, Aug.

5, after the close, which means the market has had no new information to react to all week.

Wall Street analysts have not turned either.

The consensus rating is Buy, with an average price forecast of $1,755.75, according to Analyst Ratings data — above where the stock trades today.

The most recent research went the other way entirely.

Bank of America analyst Wamsi Mohan reiterated a Buy and lifted his price objective to $2,500 on July 1, telling clients the NAND supply squeeze runs through 2027.

Bernstein raised its target to $3,000 on June 30.

Citigroup went to $2,500 on June 25.

Nobody downgraded into this week.

The SanDisk selloff has not a verdict on the business.
