CLOSING BELL
Semi Cousin Stocks Soar

The market climbed Tuesday to fresh all time closing records for the S&P 500 and Dow Jones Industrial Average. Who said Donroe Doctrine threats would hurt equities?

It may have been a wash of analyst upgrades hitting AI Semi and computer RAM stocks this week, sending names like Sandisk and Western Digital climbing. The CES conference also helped punctuate the need for memory and data center service providers, sending AI related stocks climbing.  

It wasn’t all good news hitting stocks - MSCI, a major issuer of ETF products, officially said they are not including bitcoin and crypto treasuries in their indexes, setting some pretty bleak implications for stocks like $MSTR ( ▲ 2.44% ) and Bitmine. Crypto treasury firms spread like a rash this year, but many hit their hype peak, and all-time high, back in October. While the Santa rally did not arrive, it did come through for Bitcoin prices, our Cryptotwits writer informed us today, though Bitcoin saw its first-ever negative post-halving year in 2025.

In politics, Trump made remarks at a Republican party retreat Tuesday, putting winning midterms as a top priority, or else he said he would be impeached. He also said aquiring Greenalnd was a priority, sending Critical Materials $CRML ( ▲ 16.43% ) flying, a miner that owns rare earth projects there.

The U.S. Services PMI from December showed the weakest climb for eight months, adding to rate cut hopes.

STOCKS
CES and the Storage Supercycle 

It’s day two of CES 2026 in Las Vegas, as Stocktwits reporters tread the hallowed casino halls, retail traders react to a massive reshuffling across the AI infrastructure stack.

SanDisk $SNDK ( ▲ 1.12% ) shares were leading the pack, ip bigtime today, bringing its six month climb past 750% after Nvidia CEO Jensen Huang called memory storage an "unserved market" for AI. Investors are pivoting to storage names like Western Digital $WDC ( ▼ 8.89% ) as memory bandwidth becomes the primary bottleneck for data center build-outs in the new year. 💾

Texas Instruments $TXN ( ▼ 3.33% ) joined the rally, as investor optimism for a 2026 analog chip recovery grew. AMD CEO also appeared in a keynote at CES, and despite a brand-new Helios computing system demo, the stock fell Tuesday in competition with Nvidia’s wireless data center shelf from earlier in the day.

Other stocks that might compete with the new tech were falling. Cooling giants like Modine $MOD ( ▼ 7.92% ) and Johnson Controls $JCI ( ▼ 1.35% ) plummeted after Jensen Huang showed his Rubin chips can be liquid-cooled without traditional water chillers. $SMCI ( ▼ 1.74% ), a data center shelf maker, did not enjoy the same brutal price action. ❄️

While the show went on, chip names were still catching stray updates form anlytsts.

Microchip Technology $MCHP ( ▼ 1.24% ) shares surged 11% after the company announced fiscal third-quarter revenue will significantly exceed previous forecasts due to strong bookings. It got a price upgrade from JPM.

It wasn’t just passing comments and analyst upgrades that moved stocks Tuesday.

Though not a publicly traded firm, Elon Musk’s xAI closed a massive $20B Series E round with strategic backing from Nvidia and Cisco, comfortably exceeding its original $15B target. The fresh capital will fund the expansion of the "Colossus" supercomputer to over one million Nvidia H100 equivalents to accelerate the training of the upcoming Grok 5 model.

Mobileye $MBLY ( ▲ 0.49% ) climbed after the firm announced a $900M acquisition of Israeli startup Mentee Robotics at CES, to merge automotive AI with general-purpose humanoid robots. CEO Amnon Shashua described the deal as the start of a "Physical AI" era where context-aware reasoning will power robots designed for factories and homes. 🤖

Intel $INTC ( ▲ 6.47% ) shares were up following the official debut of its "Core Ultra Series 3" processors built on the advanced 18A process. Industry watchers say the launch is a critical attempt to reclaim market share from ARM-based rivals, hoping to win some mobile computing hardware sales. $QCOM ( ▼ 1.24% ) also dropped a new PC chip, the Snapdragon X2 for Androids. 💻
