Micron stock rises in premarket as AI-era memory pricing stays in focus — what MU investors watch next

Micron stock rises in premarket as AI-era memory pricing stays in focus — what MU investors watch next

NEW YORK, Jan 5, 2026, 05:59 ET — Premarket Micron Technology (MU.O) shares rose about 3% in premarket trading on Monday, adding to a powerful run that saw the stock jump 10.5% on Friday’s close. Shares were indicated at $325.37 after ending Friday at $315.42. The Wall Street Journal The move matters because Micron’s fortunes swing with memory prices, and investors are betting this cycle has shifted in its favor. Demand from data centers building out artificial intelligence systems is pulling in more DRAM — the working memory inside servers — and more high-end variants that carry fatter margins. That

KLA stock jumps toward a fresh high as chip-equipment rally kicks off 2026

KLA stock jumps toward a fresh high as chip-equipment rally kicks off 2026

NEW YORK, January 4, 2026, 20:49 ET — Market closed KLA Corp (KLAC) shares surged nearly 5% on Friday, ending the first trading session of 2026 within about 1% of their 52-week high after chip-linked stocks rebounded. KLA Corporation The move matters now because KLA sells process-control tools — equipment that inspects wafers and identifies defects to lift “yield,” the share of usable chips coming off a production line. Those orders are a read-through on semiconductor capital spending, a key driver for the equipment group. KLA Corporation Next catalysts are split between the macro calendar and the company’s earnings setup.

NEW YORK, January 4, 2026, 20:19 ET — Market closed Texas Instruments Inc shares closed up 2.32% at $177.52 on Friday, snapping a four-session losing streak. The stock traded about 6.1 million shares and is roughly 20% below its 52-week high of $221.69, MarketWatch data showed.

Applied Materials stock jumps 4.6% as chip rally kicks off 2026 — what moves AMAT next

NEW YORK, January 4, 2026, 18:02 ET — Market closed Applied Materials (AMAT.O) shares closed up 4.6% on Friday at $268.87, after swinging between $260 and $271.21 in the session. The move matters now because semiconductor equipment makers sit early in the chip supply chain. When chipmakers lift factory spending, orders for deposition and etch tools usually follow, and the stocks often move first. With AMAT back near recent highs after a choppy end to December, investors are looking for proof that AI-linked capital spending can stay strong even as rate expectations and trade policy remain in flux.

Lam Research stock hits a record close after Citi spotlight — what LRCX investors watch next

NEW YORK, January 4, 2026, 17:49 ET — Market closed Lam Research Corp (LRCX) shares closed up 8.1% on Friday at $185.06, lifting the chipmaking-equipment maker to a record close after the stock hit an intraday high of $185.88. The sharp move matters heading into the first full trading week of 2026, with investors weighing fresh economic data and an approaching earnings slate that can reprice high-growth tech stocks in a hurry. Chip-tool names have been early leaders as investors lean into the AI buildout trade, but the group tends to react quickly when bond yields move on macro surprises.

Micron stock jumps 10% on Bernstein’s $330 target — what MU investors watch before Monday’s open

New York, Jan 4, 2026, 16:21 ET — Market closed Micron Technology (MU) heads into Monday’s U.S. reopen after a sharp Friday rally that lifted the memory-chip maker 10.5% to $315.42. The stock hit an intraday high of $319.60, reflecting heavy momentum into the first full week of 2026. The move matters because Micron sits near the center of the “AI buildout” trade: more servers and accelerators typically mean more demand for memory chips, which can lift prices and margins when supply is tight. Investors have treated memory pricing as the swing factor, and Friday’s jump suggests the market is

Texas Instruments stock rises with chip rebound — the catalysts investors watch next

New York, January 4, 2026, 15:46 ET — Market closed Texas Instruments (TXN.O) shares rose 2.3% on Friday to $177.52, tracking a broad rebound in chipmakers that helped Wall Street start 2026 higher. With U.S. markets closed on Sunday, the question for Monday’s session is whether the semiconductor bounce holds as investors brace for a heavy week of economic data and shifting expectations for interest rates. That matters for Texas Instruments because its analog and embedded chips are closely tied to industrial and automotive demand, areas that tend to react quickly when growth expectations or financing conditions change.

NEW YORK, Jan 4, 2026, 10:48 ET — Market closed Lam Research shares rose 8.1% on Friday to close at $185.06, after the chip-equipment maker was named to Citi’s Large Cap Recommended list for 2026.
