SanDisk's 2,107% Surge Upends Value Indexes

SanDisk's explosive growth over the past year has caught the attention of Morningstar's chief global markets editor, Tom Lauricella. The company's stock price has surged an astonishing 2,107% in one year, making it the biggest winner on the market.

This remarkable performance has caused a ripple effect, with value indexes nearly doubling their tech weighting from 11% to 20%. As a result, Apple and Microsoft now appear as discount stocks due to their position in the rankings. Lauricella notes that this is an unusual occurrence, particularly given the AI storage buildout that is driving SanDisk's success.

The company's fundamentals are doing most of the heavy lifting, with revenue increasing 371.6% year-over-year to $8.96B in its fiscal Q4 report. Non-GAAP EPS came in at $39.25, exceeding consensus estimates by a wide margin. GAAP gross margin reached an impressive 84.6%, up 58.4 percentage points from the previous year.

SanDisk's Datacenter segment is where the AI narrative earns its keep, with revenue growing 437% year-over-year to $2.977B in Q4. Management attributed this growth to both volume and pricing increases, with a robust pipeline of new business agreements.
