Sandisk (SNDK) is back in focus after broader tech stocks rebounded, with memory and data storage companies recovering some ground as Treasury yields and oil prices eased and growth names drew fresh interest.

After a sharp pullback earlier in the week, Sandisk’s 1 day share price return of 1.26% and 30 day share price return of 17.30% suggest short term momentum is rebuilding, even as the 90 day share price return is down 8.67%. The very large 1 year total shareholder return highlights how strong the overall run has been into today’s US$1,499.37 level.

After such a strong 1 year run and a sharp recent rebound, the key issue for Sandisk now is whether most of the easy gains are already behind the stock or if there is still meaningful upside ahead on valuation.
