Opendoor call volumes hit 1 million for first time ever as gamma squeeze accelerates

The door might be open, but there’s a traffic jam as everyone tries to rush through it.

Shares of Opendoor Technologies are up more than 60% on Monday, briefly breaching $4, as enthusiasm over the potential turnaround story — and the desire to chase momentum in a stock that mooned last week — continue to produce massive flows into the name.

Daily volumes and the total value of money spent trading the stock each hit a record before the session was two hours old. That’s despite the company having been about 7x larger back in 2021.

And call volumes breached 1 million for the first time ever, setting a daily record for the fifth consecutive session.

Opendoor is the easiest example of the gamma squeeze we discussed earlier playing out.

Call options volumes are accelerating and migrating up the chain, with increasing demand for the options that are out of the money but getting closer to being money-good.

For instance, the most active contract today is the call option with a strike price of $4.50 that expires this Friday. This contract had no open interest prior to today. All of these are new bets, made today, with the rush into these wagers with embedded leverage putting upward pressure on the shares.

Warner Bros. Discovery jumps after Wells Fargo ups price target on dealmaking buzz

Warner Bros. Discovery shares popped 7% Tuesday after Wells Fargo raised its price target on the media giant to $14 from $13, while keeping an equal-weight rating.

The bank’s optimism stemmed largely from the media giant’s potential for dealmaking. In June, WBD announced that it would would split its operations into two companies, with the Streaming & Studios division (home to Warner Bros. Television, DC Studios, HBO, and Max) standing alone from the networks side (CNN, TNT Sports, and Discovery).

That separation could make the Streaming & Studios unit more attractive to buyers, the analysts said. They valued the segment at about $65 billion, which could translate to a takeover price north of $21 a share. Potential suitors range from Amazon and Apple to Sony and Comcast, though analysts flagged Netflix as the “most compelling” option despite its limited acquisition track record:

“While NFLX has historically not been acquisitive, [streaming and studios’] $12bn in annual content spend + library + 100+ acre studio lot offers a lot. It kickstarts a theatrical IP strategy, quickly scales video games and most importantly provides premium content to members.”

At Goldman Sachs’ Communacopia Conference this week, CEO David Zaslav also highlighted growing traction at HBO Max and hinted at future crackdowns on password sharing.

WBD shares are up 26% year-to-date, and up over 93% over the past 12 months.

Duolingo up on bullish note, hopes for a user rebound

Duolingo rose by the most in nearly a month, as an analyst note painted a more bullish picture of the gamified language learning company despite a dearth of news otherwise.

A quick check-in with analysts covering the stock on Wall Street found most of them otherwise flummoxed on the reason behind the uptick Thursday.

Some, however, suggested the rise may reflect optimism that the company has been able to reverse a months-long downturn in daily active user metrics — a slump that set in after a social media backlash to a somewhat inartful LinkedIn post from the company about its AI first strategy.

The bullish analyst note, published Thursday by Citizens JMP, suggested Duolingo could be a big beneficiary from a change to Apple’s rules governing its App Store driven by a ruling on a Federal antitrust case against the company. The analysts wrote:

Apple’s recent changes to U.S. App Store rules that allow developers to steer payments to the web where fees are similar to typical credit card fees rather than Apple’s 30% fee for in -app purchases and 30% fee on subscriptions for the first year and 15% thereafter, we expect mobile app companies including Duolingo, Life360, and Grindr Inc. to unlock meaningful cost benefits.

At any rate, the next big event on the company’s calendar is its Duocon 2025 conference on Tuesday, where analysts are hoping to hear more hard information on all of the above topics.

Jeep maker Stellantis surges as CEO says the automaker is in productive tariff talks with the US

Shares of Jeep and Dodge maker Stellantis are up more than 8% in Thursday afternoon trading, following comments from the automaker’s new CEO, Antonio Filosa, at a European auto conference.

On tariffs, Filosa said that Stellantis has had a “very productive exchange of ideas” with the Trump administration on the company’s manufacturing footprint and that the environment around the levies is “getting clearer and clearer.”

The US is Stellantis’ top priority, according to Filosa, and the company has taken efforts to turn things around in the market, where it’s struggled with sales in recent years. To fuel the turnaround, Stellantis is bringing back its popular Jeep Cherokee, which it discontinued in 2023.

As of 12:45 p.m. ET, Stellantis’ trading volume was at more than 140% of its average over the past 30 days.

Tempus AI jumps on FDA clearance of AI-enabled tool to analyze cardiac MRIs

Tempus AI, a midcap medical diagnostics company that’s highlighted a push to incorporate AI technology into its products, surged on Thursday after announcing the FDA had issued a “510(k) clearance” of a new AI-enabled tool to analyze cardiac imagery from MRIs.

A 510(k) clearance — used for devices that are considered relatively low risk — essentially allows a product to be sold in the US.

While the company has never turned a profit, even on an adjusted basis, its sales are growing rapidly and the stock has had a great year, rising more than 160% in 2025.

Micron surges as Citi boosts price target to $175

Micron is on the move this morning, gapping higher and continuing to trade up double digits after Citi boosted its view on how much the shares can run.

Analyst Christopher Danely raised his price target on the memory chipmaking specialist to $175 from $150, while maintaining a “buy” rating. The average analyst price target of $151 has now been shattered by Micron’s rise today, and the stock is trading at its highest level since June 2024.

This continues Micron’s advance as OpenAI’s dogged determination to burn through cash to enhance its AI capabilities provides a broad lift to the space, punctuated by Oracle’s massive gain on Wednesday.

Call demand is running hot: just 13 minutes into the session, volumes are running at 106,157 compared to a 20-day average of 88,888.

Micron is slated to report quarterly results on September 23.
