Memory chip stocks fall into a bull market amid latest tech sell-off

July 8, 2026 - 01:20

Memory chip stocks have taken a sharp turn lower, pulling the sector into bear market territory as the broader technology sell-off accelerates. Yahoo Finance Markets and Data Editor Jared Blikre examined the intraday moves of three major players -- Micron Technology, SK Hynix, and Samsung -- and found that all three have dragged the group into a sustained downturn.

Micron shares have fallen more than 20% from recent highs, while SK Hynix and Samsung have also posted steep declines. The drop marks a stark reversal for a sector that had been riding high on artificial intelligence demand. Investors had piled into memory chip makers on hopes that AI workloads would require massive amounts of high-bandwidth memory. But those expectations are now being tested as concerns over oversupply, weakening demand in other end markets, and a broader rotation out of tech stocks weigh on sentiment.

The sell-off is not isolated to memory chips. The broader semiconductor index has also struggled, with the Philadelphia Semiconductor Index slipping into correction territory. Analysts warn that the memory chip cycle may be turning earlier than expected, as traditional demand from smartphones and PCs remains sluggish. For now, the sector's bull run appears to have run its course, at least for the near term.
