As momentum trade fades, Duolingo drops into negative territory for the year

Retail fave Duolingo dove Friday as part of a sudden reversal in the momentum trade that has dominated the market after its tariff-driven April 8 lows.

There was no obvious news or corporate event catalyzing the tumble, though the stock has been under a bit of scrutiny over the last week, since Google unveiled an AI-assisted real-time translation tool that some say could pose a threat to the language-learning app.

The Google news wasn’t a shocker, though. We posed questions about the strategic threat AI might pose to Duolingo when Sherwood News talked to Duolingo CEO Luis von Ahn almost a year ago. And mounting concerns about AI competition don’t explain the suddenness of Friday’s sell-off.

Whatever the cause, the depth of the tumble was enough to push Duolingo shares firmly into the red for 2025, a position it hasn’t been in since March, which — coincidentally — was when a major reversal also hit momentum shares.

That sell-off was worsened by the Trump administration’s April tariff announcement, which came close to pushing the S&P 500 into a bear market before the administration backed away from tariffs, setting off a massive rally.

Report: US senators plan to introduce bill blocking Nvidia from selling advanced chips to China for 30 months

US senators are on the verge of introducing a bill that would block Nvidia from selling its H200 or Blackwell chips to China for 30 months, the Financial Times reports. The H200 is Nvidia’s best chip from the Hopper generation, while the Blackwell line is its current flagship offering.

Shares of the chip designer are little changed in the wake of this report, still up more than 1% on the session. The reaction makes sense, seeing as previous positive indications on Nvidia’s ability to sell advanced chips to China failed to inspire much positive momentum in its shares.

The stock got a short-lived jolt higher (that didn’t last the day!) on November 21 after Bloomberg reported that the Trump administration had discussed the possibility of selling its H200 chips to China.

Nvidia has effectively been shut out of China’s AI market in 2025. First, export restrictions meant it could no longer sell the H20, a nerfed version of its Hopper chip, to the world’s second-largest economy. After that export ban was lifted, demand from China “never materialized,” per Nvidia CFO Colette Kress. Reports indicate that China banned its leading technology giants from purchasing these semiconductors, instead pushing them toward domestic alternatives.

President Donald Trump had mused about allowing Nvidia to sell Blackwell chips to China prior to his meeting with Chinese President Xi in late October, but failed to do so. The two leaders did not discuss the topic at that time.

Per the FT, this upcoming bill would be a bipartisan effort, being cosponsored by the leading Republican and Democrat members of the Senate Foreign Relations East Asia subcommittee.

AI energy plays soar on an explosion of call buying

Like their quantum computing counterparts, AI-linked energy plays are benefiting from an explosion of bullish options activity on Thursday.

Oklo is up double digits with call volumes above 106,000 as of 2:46 p.m. ET, more than double its 20-day average for a full session, with a put/call ratio of about 0.6. Call options with a strike price of $110 that expire this Friday (which are now in-the-money thanks to today’s surge) are seeing the most activity.
Nuscale, another nuclear energy play, has seen nearly 140,000 call options change hands versus a 20-day average of 51,073.
And fuel cell company Bloom Energy has traded nearly 80,000 calls, roughly twice its 20-day average, with a put/call ratio of about 0.3.

During his appearance on Joe Rogan’s podcast released on Wednesday, Nvidia CEO Jensen Huang talked up the potential for nuclear energy, saying, “In the next six to seven years I think you are going to see a whole bunch of small nuclear reactors.”

This adds to the evidence that the speculative bid is back in a big way after smaller stocks tied to the AI boom and quantum computing cratered from mid-October through most of November as credit risk began to seep into the AI trade.

Space stocks rip amid speculation on Altman joining race

Space stocks AST SpaceMobile, Planet Labs, and Rocket Lab all soared Thursday amid a recovery in the high-beta momentum class of shares coveted by some retail traders.

(High-beta momo stocks are basically shares that have been on a winning streak for a while, and tend to go up a lot more than the overall market on positive days. Goldman Sachs includes all three of the aforementioned space stocks in its themed basket of such shares.)

There’s little other fundamental news out there on the companies themselves.

But a Wall Street Journal report that OpenAI impresario Sam Altman has been toying with the idea of entering the space industry, potentially standing up a rival to Tesla CEO Elon Musk’s Starlink satellite service, may also be contributing.

As we’ve mentioned elsewhere, sometimes these stocks seem to trade on a what’s-bad-for-the-Musk-empire-is-good-for-us-and-vice-versa vibe.
