Sandisk's 1,100% Rally Causes $3 Billion Short-Seller Loss
Sandisk Corp.'s stock has gone up a lot, over 1,100% in just six months.
This big increase has caused people who bet against the stock, called short-sellers, to lose a lot of money, around $3 billion.
Even though they're losing money, more people are still betting against the stock, which could make things even more risky.
The stock is going up because there's a big need for storage stuff, like memory cards and flash drives, and there's not enough of it.
The company's CEO and other important people have also said good things about the storage market, which has helped the stock go up even more.
Sandisk Corp.'s stock has surged 1,117% in six months, causing $3 billion in losses for short-sellers.
Short interest has risen to 7.5% of the total float, indicating aggressive short-selling.
The rally is driven by AI-trade focus on storage stocks and a shortage of flash memory.
S3 Partners' risk score for Sandisk is at 82.5, described as 'extreme'.
Sandisk was spun off from Western Digital Corp. in February 2025 and has since seen a 1,300% stock increase.
