Flurry of positive announcements make ImmunityBio the next short squeeze target for retail traders

Heavily shorted ImmnuityBio is continuing its stellar run, up big in premarket trading after management delivered its fourth and fifth doses of positive news for the week.

In a pair of press releases, the biotech company said that:

  • A trial aiming to advance the utilization of its bladder cancer drug (ANKTIVA) is over 85% complete, with interim analysis having been positive.

  • A study of one of its treatments delivered in concert with another drug helped patients stay clear of Waldenstrom Non-Hodgkins Lymphoma for up to 15 months.

At their premarket peak on Friday, shares had more than doubled on the week.

The stock jumped 30% on Thursday after management said that ANKTIVA volume sales rose 750% in 2025. That came on the heels of a 7% rise on Wednesday after Saudi Arabia approved this drug as part of a treatment for bladder cancer and non-small cell lung cancer. And that followed a release from the company on Tuesday about how ANKTIVA “demonstrated statistically significant immune restoration across two clinical trials in 151 patients with non-small cell lung cancer,” driving shares up nearly 9%.

About 36.5% of the company’s shares were sold short as of the start of this year, and retail traders are clearly of the view that those betting against the company will be forced to capitulate amid this litany of positive releases. As of 7:30 a.m. ET, two of the top three posts on the r/ShortSqueeze subreddit center on the biotech firm, with one of these a cross-post from r/WallStreetBets of a more than $90,000 position initiated after the close on Thursday.

This may be another instance in which the term “short squeeze” looks like a bit of a misnomer: as of year-end 2025, about 120.6 million shares of IBRX were sold short, per exchange data. Cumulative volumes over the past three full sessions have been above 150 million. So going forward, if there are shorts left to be squeezed, it’s because this three-day spike (going on four days!) had much more to do with a buyer’s binge thanks to this string of encouraging news.

SpaceX gets a wave of bullish ratings from Wall Street analysts

SpaceX received more than a dozen positive analyst calls on Tuesday — including from major Wall Street banks — as they initiate coverage on Elon Musk’s space and AI company.

SpaceX went public on June 12 at a $2.2 trillion valuation, the largest debut in history. While the company hasn’t yet posted a profit, it seems to have convinced Wall Street that it will get there and grow its valuation on the way.

Of the at least 17 analysts that gave a rating on Tuesday, all but one gave it a “buy” or “outperform” rating. MoffettNathanson was "neutral."

The ratings come as SpaceX joined the Nasdaq 100 index, a benchmark tech-heavy basket of companies that underpins millions of portfolios. The inclusion adds built-in demand for the stock from index funds and ETFs.

Still, SpaceX fell more than 5% on Tuesday amid a broader sell-off, and is currently effectively flat from its opening price of $150 a share.

Nike sinks to lowest level since 2014 after warning of “challenged” sales environment in Q4 report

Did Nike do it?

Investors had a mixed reaction after the global sports apparel company reported its fourth quarter earnings on Tuesday after the bell. Shares initially rose 5% as Nike beat out Wall Street expectations amid a hefty tariff refund bonus. However, the stock then sank to its lowest level since August 2014 in postmarket trading.

Here are the Q4 numbers:

  • Revenue of $11.0 billion (estimate: $10.8 billion).

  • Adjusted earnings per share of $0.20 (estimate: $0.12).

Ahead of this report, Nike warned that results would be flattered by a one-time tariff refund (now estimated at roughly $0.52 per share for the bottom line). That gave the company an extra cushion in snapping its streak of seven quarters of year-over-year profit declines.

Over the past year, the company had been punished by tariffs on imported goods, stagnant consumer spending, and increasing competition from other footwear brands like New Balance, Adidas, and Hoka.

Outgoing CFO Matthew Friend deemed it an “increasingly challenging operating environment, where sell-through remains challenged.”
