SanDisk to Join S&P 500 index After Stock Surge This Year -- Barrons.com

Dow Jones

Nov 25

Andrew Bary

SanDisk, the maker of memory chips , will join the S&P 500 index and replace Interpublic Group of Companies before the start of trading on Nov. 28.

SanDisk, a spinoff in February from Western Digital, has surged since the spinoff, rising more than fourfold to a closing price of $226.96 Monday. The stock was up 13.3% Monday, and has gained another 9.4% in after-hours trading to $248.39.

SanDisk has benefited from surging demand for flash memory and other chips that it produces. With a market value of close to $30 billion, SanDisk was the largest company by far in the S&P Small Cap 600 index. It's rare for a company to make the leap from the small-cap index to the S&P 500.
