Oklo rises as Barclays initiates the stock at “overweight”

Trendy nuclear power stock Oklo received a bullish review from Wall Street on Monday, with Barclays analysts starting coverage of the stock at “overweight” — basically a “buy” rating — alongside a price target of $146, a more than 30% premium to Friday’s close.

The underlying rationale is, of course, the AI data center boom, which is already boosting electricity demand — and raising utility bills — and is projected to do so for years to come.

Shares were up 5.8% premarket. Before today, the stock had soared more than 50% over the past month, but that includes a bit of a retrenchment over the past few sessions.

As a maker of small modular nuclear reactors (SMRs), Oklo and similar companies like Nuscale are seen as providing a possible technology that can bridge the growing gap between supply and projected demand.

But this is all very speculative, as these companies are not actually producing much of anything at the moment besides outstanding stock market returns.

Barclays analysts note that Oklo’s business currently encompasses a series of “non-binding agreements with various customers, such as data centers, military outposts, etc,” and Wall Street forecasts annual losses for the company through 2028.

Barclays analysts write of the shares:

“OKLO is up more than 5x YTD while SMR has more than doubled to ~$38 vs. the S&P, which is up 13%. Market caps are sizeable at $16.5 bn for OKLO and $11 bn for SMR despite having no binding contracts and still awaiting regulatory approvals.

Generally, we think that the macro news, such as policy or trade updates we get from the Administration (which tend to be more positive than not), and headlines around how the world is short power, will be the largest drivers to stock price reaction while announcements for any binding agreements should also act as a positive catalyst.

Negative reactions to the stock will likely come more in the form of company specific news — i.e. timelines slipping, regulatory and/or execution setbacks...

In the near-term, we are inclined to think that we will get more macro news while updates around any execution issues won’t be for several years (especially as neither company has started construction and commencement of operations is still years away).”

Arista Networks rips higher amid jump in call buying

Arista Networks, a maker of switches and other networking equipment used in AI data centers, was on track for its best day of the new year on Thursday as options traders went bullish on the stock.

As of around 11 a.m. ET, there was nearly twice as much call buying in Arista than its 10-day moving average for a full day of activity. Buying call options to make leveraged bets on price increases has been a favorite trading tactic of retail traders in recent years.

Otherwise, there weren’t clear headlines tied to today’s outsized move, but the stock has been getting attention lately: in a note published earlier this month, Goldman Sachs analysts spotlighted Arista as a top tactical trade for earnings season, saying the shares — which they rate a “buy” — could rise 20% over the next year.

“ANET is well positioned amidst ongoing data center spending growth, where its position as a best of breed provider of networking equipment should advantage the company, particularly as data center networks become increasingly complex,” Goldman analysts wrote in the January 8 report.

And recent reports also say Microsoft — which accounted for 20% of Arista’s revenue in 2024, according to Goldman Sachs — is planning a massive expansion of its Wisconsin data center project.

Arista stock did get a lift following the release of solid US economic numbers at 8:30 a.m. that seemed fairly specific to Arista itself. (There was no similar bounce from competitors like Cisco or Hewlett-Packard.)

Investors just made a mammoth $133 billion flip from cash to stocks, per Goldman Sachs

It’s a dash from cash, with investors taking billions in dry powder and pouring that money into the stock market.

“We saw strong net flows into global equity funds last week, led by stronger inflows into US and EM equity funds (+$71 billion vs $2 billion in the previous week) — more than 35x-ed the flows,” wrote Goldman Sachs’ Gail Hafif, Brian Garrett, and Lee Coppersmith. “While equity flows increase, money market fund assets fell by $62 billion. This is the 3rd largest level in our dataset (!).”

Goldman cash to stocks flows

The trio is bullish on US stocks, seeing “the case for contained selloffs coupled with relief rallies as the most likely path forward in the near term.”

Moderna extends rally on positive cancer vaccine results

Moderna has more than doubled since it announced on Tuesday that its cancer vaccine reduced the risk of relapse or death for melanoma patients.

The five-year data from a Phase 2b trial showed that Moderna’s vaccine, when used with Merck’s blockbuster treatment Keytruda, reduced the risk of recurrence or death by 49% compared with Keytruda alone. The news gave investors hope that Moderna, which is best known for quickly developing a COVID-19 vaccine, may soon have another lucrative product in its portfolio.

Last week, Moderna said it expects to report total 2025 revenue of $1.9 billion, on the high end of its latest guidance of between $1.6 billion and $2 billion, amid better-than-expected vaccination rates. As demand for the COVID-19 vaccine, its sole revenue-generating product, has tanked, the company has aggressively cut costs and focused on expanding its portfolio.

The combination of positive announcements early in the year has made Moderna the second-best performer in the S&P 500 Index in 2026, behind newfound AI darling Sandisk.

POET Technologies tumbles after announcing $150 million direct share offering

POET Technologies is tumbling in early trading Thursday after the optical communications company announced that it’s raising $150 million through the sale of about 20.7 million shares in a registered direct offering.

It’s an opportunity for management to cash in on the stock’s more than 30% rally year to date (as of Wednesday’s close).

“With a substantial base of cash, we plan to accelerate our pursuit of targeted acquisitions, add to our capabilities and talent base, vertically integrate our products with differentiated components, and expand operations to pursue revenue opportunities across the board, in order to bring long-term value to shareholders,” Executive Chairman and CEO Dr. Suresh Venkatesan said.

POET’s last offering came in late October, after which shares nearly halved in less than a month amid a broad drawdown in speculative, volatile stocks beloved by retail traders.
