Among the big three memory chip makers, US-based Micron has shown notable strength, while SK Hynix has given back most of its gains from the current cycle.

According to TradingBeats' monitoring, contracts for Micron, SK Hynix, and SanDisk on Hyperliquid have all declined notably from their respective peaks since the late-July rebound. However, their relative strength during that prior rebound phase varied: Micron is currently the most resilient to drops, while SK Hynix has recorded the largest pullback. Micron (MU) has fallen from its October 2 high of $1,114.90 to $923.62, a total pullback of roughly 17.16%—the smallest among the three. SanDisk (SNDK) has dropped from its September 22 high of $1,908 to $1,378.40, a total pullback of around 27.76%, roughly 10.60 percentage points more than Micron. SK Hynix (SKHX) has fallen from its September 10 high of $1,438.40 to $958.73, a total pullback of around 33.35%—the largest among the three, underperforming Micron by approximately 16.19 percentage points. During the earlier rebound period, however, the top performer was SanDisk, which now sits in the middle of the three in terms of pullbacks, while Micron posted the smallest gains. Using the July 31 intraday lows of each asset as the storage sector's trough, SanDisk rallied to a peak of roughly 60.27%, SK Hynix to around 38.73%, and Micron to about 36.14%.
