Oklo, nuke stocks battered amid speculative stock and momentum unwind

Amid a broader unwind of momentum trades, stocks tied to the nuclear-powered AI trade — Oklo, Nano Nuclear, and Centrus Energy among them — are taking a particularly hard beating.

JPMorgan strategist Arun Jain estimates that retail traders have dumped $24 million in Oklo shares through 11 a.m. ET.

This tumble comes alongside a tough-minded story from the Financial Times examining the prospects of this zero-revenue company, which as of yesterday had a market value of $20.6 billion. (It’s below $18 billion after today’s drop.)

Of Oklo’s plans to build smaller nuclear reactors using liquid sodium as a coolant rather than water, the salmon-toned periodical wrote:

“Some experts point to the failure of sodium-cooled reactors built in the US between 1950 and 1976.

Critics also note proliferation risks because Oklo’s plans would see plutonium move into private industry hands, where it could be at risk of diversion or theft by those who seek to build an atomic bomb. A decision by the US Nuclear Regulatory Commission to reject a previous Oklo application to build a sodium-cooled reactor in 2022 has also raised questions.

‘That NRC deemed Oklo beyond help should be a red flag,’ said Allison Macfarlane, a geologist and former chair at the regulator now at the University of British Columbia.

‘Liquid sodium is highly corrosive, flammable and explosive on contact with air and water,’ she said. ‘Many countries have tried to build these reactors before but they haven’t managed to prove they are commercially viable at scale.

Rivian sure picked a bad time for its AI Day as investors dump tech stocks

The event coordination team at Rivian is probably having a bad one, as investors dumped the stock ahead of its “Autonomy and AI Day” amid a broader AI trade sell-off.

Heading into the event that began at noon ET, Rivian shares were down 5%, following a strongly negative reaction to Oracle’s earnings results. The stock began climbing as Rivian’s event started, but remains in the red on the day.

A year flush with tariffs and the end of the EV tax credit has pushed Rivian to pitch a techier version of its future. During Thursday’s event, Rivian said its forthcoming vehicles would ditch Nvidia chips for its own AI chips produced by Taiwan Semiconductor.

The vehicles will feature lidar sensors, enabling “level 4” autonomous driving (similar to Google’s Waymo), the company said. According to CEO RJ Scaringe, the updates will allow Rivian to “pursue opportunities in the rideshare space,” hinting at future robotaxi plans, which rivals Tesla and Lucid have already begun.

Wall Street appears skeptical of Rivian, with Morgan Stanley this week downgrading the stock to “underweight” and dropping its price target to $12. Lucid, which in October announced it’s planning a privately owned autonomous car built with Nvidia tech, also received a downgrade.

Robinhood tumbles after November trading volumes post monthly drop across equities, options, and crypto

Robinhood Markets is getting crushed today, and not just because it’s the place where people go to buy AI stocks (which are under big pressure after Oracle’s earnings report). As stocks retreated in November, activity on the platform did, too.

(Robinhood Markets Inc. is the parent company of Sherwood Media, an independently operated media company subject to certain legal and regulatory restrictions.)

The brokerage reported that November trading volumes fell across equities, options, and crypto compared to October. Equity notional volumes were down 37% month on month, options contracts traded were off 28%, and crypto notional volumes fell double digits. The bright spot: its prediction markets business is still in boom mode, with 3 billion contracts traded, up 20% versus the prior month.

Cantor Fitzgerald analyst Brett Knoblauch trimmed his price target on the shares to $152 from $155 following this release, noting that this monthly decline was somewhat expected.

Oracle’s underwhelming results are kneecapping the AI trade

The nasty reception to Oracle’s quarterly results, which included a small revenue miss along with much more capex and cash burn than analysts had anticipated, is cascading through the rest of the AI trade.

Among the names getting hit hard:

While stocks have recovered strongly since their November 20 intermediate low, that’s been more about bullishness on Google and its partners as well as global growth than the AI trade broadly.

Only one member of the VanEck Semiconductor ETF is negative during this time: Nvidia. The second-worst performer of the bunch over this stretch is AMD, another AI GPU provider.

PetMed soars after disclosing $4-per-share buyout offer from investment firm

PetMed Express soared after disclosing that it had received a take-private buyout offer from Singapore investment firm SilverCape Investments, valuing the company at a significant premium.

PetMed said its board would evaluate the offer.
