Retail traders’ monthly appetite for stocks ascends to fresh record

“The current ‘new year’ momentum has been sustained and has now pushed retail activity to an all-time high on a rolling monthly basis,” according to JPMorgan.

With an insatiable appetite for both single stocks and ETFs to kick off 2026, retails traders have bought themselves into the record books.

“Retail investors continue to set new records this year — reaching an impressive $12.9B this week,” JPMorgan strategist Arun Jain wrote. “This level is comparable to last year’s buy-the-dip episodes (post-DeepSeek, March Momentum Unwind and the V-Shape recovery in April); but unlike those prior episodes, which faded quickly, the current ‘new year’ momentum has been sustained and has now pushed retail activity to an all-time high on a rolling monthly basis.”

Tuesday, when stocks slumped amid tariff and geopolitical tensions, was the third-largest trading day of the past year for retail, per Jain.

An elevated retail presence has unsurprisingly coincided with a strong start to the year for more volatile pockets of the market.

“Improving macroeconomic conditions, firmer growth expectations, and a shift toward more cyclical outcomes have encouraged investors to take on risk,” wrote Dave Mazza, chief executive officer of Roundhill Investments and portfolio manager of the Roundhill Meme Stock ETF. “As confidence has improved, market leadership has broadened beyond mega-cap growth into higher-beta, volatility-sensitive areas.”

In a January 20 email, he flagged Sandisk, Bloom Energy, and Applied Digital as members of the ETF among the chief beneficiaries from “improving price momentum, elevated trading activity, and sustained retail engagement.”

While the current retail footprint in the market has evoked some comparisons to 2021 (well, by me at least), Cboe’s Henry Schwartz, vice president of derivatives market intelligence, pointed out one sign in the options market that there’s less exuberance than in those heady days: the share of single stocks whose calls trade at a higher implied volatility than puts is well shy of its early 2021 peak.

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 (!).”

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.

Oracle gains amid report that the TikTok deal is poised to close this week

Oracle is gaining in premarket trading as Semafor reports that China and the US have signed off on the sale of TikTok’s US operations to a consortium in which the software giant is one of the three leading investors.

The transaction is poised to close this week, per the report, citing people familiar with the situation.

In mid-December, Oracle booked a huge gain after the CEO of TikTok owner ByteDance indicated that he’d signed contracts with Oracle and the other major investors leading this consortium, private equity firm Silver Lake and Abu Dhabi-backed tech investment company MGX.

If, as previous reporting suggested, the transaction values TikTok’s US operations at about $14 billion, that would mark a fairly low price tag for a lot of eyeballs and ad dollars. This pact will also afford Oracle’s cloud business an opportunity to deepen its preexisting relationship with TikTok.
