Catenaa, Friday, October 16, 2026- Memory chip stocks such as Samsung, Micron and SK Hynix shed over $700 billion in combined market value in 7 trading sessions.
According to Yahoo Finance, Samsung, Micron, SK Hynix and SanDisk, all DRAM components, have shed more than $700 billion in combined market value since October 6.
Roundhill Memory ETF plunged nearly 45% from June to late July, then rallied over 40% into September. The latest selling has erased more than three-quarters of that recovery.
Zacks said that with the recent sell-off, Micron shares are now extremely cheap. The memory leader sports a P/E ratio of just 12x, while Wall Street analysts expect revenue and EPS to grow at a triple-digit clip.
A broader Yahoo Finance basket of 61 semiconductor and storage stocks has lost nearly $2.5 trillion.
According to Yahoo Finance, the DRAM has fallen back into bear-market territory. By Thursday, the fund was approximately 22% below its September recovery high and nearly 40% below the record closing level reached in June.
The bleeding of memory chip leaders started after China’s CXMT announced progress on a denser memory-chip design, raising concerns about competition and pricing power.
Yet the challenger fell more than 5% Thursday, leaving it down roughly 20% since September’s end. DRAM holds it as well, with roughly 5% exposure as of September 30.
Yahoo Finance reported that Samsung plunged nearly 10% Thursday in Seoul, before US trading began. The subsequent US rebound helped Micron finish nearly 2% higher, but the iShares Semiconductor ETF still posted its eighth straight decline, its longest losing streak since October 2008.
Strong demand hasn’t stopped investors from questioning future profits.
Meanwhile, Yahoo Finance said that chipmakers helping finance their customers are attracting more scrutiny. That doesn’t mean AI demand has disappeared.
TSMC reported another record quarterly profit Thursday. Investors are questioning how much of the boom will reach shareholders.
From a technical perspective, the Roundhill Memory ETF could face an important support level near $45, around 9% below Thursday’s closing price. A decline below that level would indicate further weakness and could reverse the fund’s recovery from its July lows.
