Shares of BigBear.ai Holdings Inc (NYSE:BBAI) are trading sharply higher Tuesday afternoon, up some 21% to $5.06. The rally comes without any new company-specific announcements, suggesting the upward momentum is potentially building upon recent positive developments and overall market strength.

What To Know: Last week, the AI solutions provider confirmed it had deployed its biometric passenger processing software at major U.S. and international airports, including JFK, LAX and Chicago O’Hare.

The technology, developed by its recent acquisition Pangiam, aims to streamline international arrivals and enhance security in partnership with U.S. Customs and Border Protection.

Earlier in the month, on June 11, BigBear.ai announced a strategic partnership with Easy Lease PJSC to accelerate AI development and deployment in the United Arab Emirates. CEO Kevin McAleenan called the collaboration a “major first step” in the company’s international expansion plans.

What Else: According to data from Benzinga Pro, Tuesday’s trading volume eclipsed 219 million shares, far surpassing its 100-day average of approximately 78.6 million. This buying frenzy is particularly noteworthy given the stock’s significant short interest.

With over 29% of the company’s available shares sold short, Tuesday’s sharp price increase may be intensified by a short squeeze as bearish investors rush to cover their positions.

How To Buy BBAI Stock

Besides going to a brokerage platform to purchase a share – or fractional share – of stock, you can also gain access to shares either by buying an exchange traded fund (ETF) that holds the stock itself, or by allocating yourself to a strategy in your 401(k) that would seek to acquire shares in a mutual fund or other instrument.

For example, in BigBear.ai’s case, it is in the Information Technology sector. An ETF will likely hold shares in many liquid and large companies that help track that sector, allowing an investor to gain exposure to the trends within that segment.
