OPEN SEASON

The most insane trading day for Opendoor yet, charted

Opendoor traded more than Meta in furious, frenzied trading yesterday that echoed the peak GameStop era.

7/22/25 9:45AM

The explosion of retail enthusiasm over struggling online real estate company Opendoor Technologies is propelling trading activity in the stock into the stratosphere of the most valuable, well-known companies in the world — and in many cases, well past them.

It’s hard to contextualize just how insane it is that a company that, until very recently, was a penny stock with a market cap in the hundreds of millions is now trading more than tech giant Meta.

As you would expect, trading volumes tend to correlate strongly with the market value of a stock. There are outliers, of course — Palantir is one that continues to punch above its weight — but for the most part, there’s a clear correlation between market cap and volume traded. Even in the most liquid market in the world, US equities tend to take a little over 100 days of typical trading to turn over their entire market cap.

Put another way, the average stock in the S&P 500 Index traded 0.87% of its market cap yesterday, per FactSet data. On a relative basis, Domino’s Pizza, which reported decent earnings yesterday thanks its efforts in the world of stuffed crusts, was the most active in the S&P 500 — turning over just under 7% of its market cap in Monday’s session.

Opendoor Technologies was completely off the charts, trading 298% of its closing market cap (an important distinction because it, uh, varied a lot yesterday).

That’s not too far off how much GameStop traded at the peak of its January 2021 frenzy: 316% of its market value.

Oil’s retreat propels US stocks higher

Front-month West Texas Intermediate futures are down more than 4%, while Brent futures are off more than 2% as of 1:25 p.m. ET as traders glom on to some optimistic signs about the flow of oil through the all-important Strait of Hormuz:

A Pakistani-owned tanker passed through the strait this weekend while broadcasting its signal, per Reuters, “indicating ‌that some countries are able to negotiate safe passage for their vessels despite the U.S.-Israeli war on Iran.”
US President Donald Trump said that some “fairly local” countries would soon be helping ships traverse the strait (while having added that other countries are “not enthusiastic” about the prospect of participating).

The SPDR S&P 500 ETF and Invesco QQQ Trust are both up over 1% amid oil’s retreat.

That being said, the news flow is far from universally positive.

Reuters reports that the UAE’s crude output has been cut in half since the Mideast conflict started; Bloomberg says Kuwait’s production has suffered a similar decline.

Sandisk and memory stocks rip ahead of Nvidia CEO’s speech

Memory stocks such as Sandisk, Micron, and disk drive makers Western Digital and Seagate sprinted ahead Monday, as this week’s big AI conference for tech bellwether Nvidia gets underway with a speech from the CEO slated for this afternoon.

As Luke Kawa pointed out earlier, CEO Jensen Huang’s speechifying at high-profile company announcements or industry events hasn’t always been a good thing for Nvidia shares. (The chip designer is holding its GPU Technology Conference, or GTC, this week.)

But Huang’s pronouncements have, at times, been pretty dang helpful for share prices of some companies in the orbit of the AI gods. Perhaps foremost among them are the memory stocks that have blasted toward the top of the S&P 500 in terms of price performance in recent years.

Case in point: the nearly 30% gain that Sandisk posted on January 6, the day after Huang’s keynote speech at the Consumer Electronics Show in Las Vegas, in which he spotlighted memory as a key bottleneck constraining the AI build-out. (Fellow memory plays Western Digital, Seagate Technology Holdings, and Micron also posted double-digit gains that day.)

Memory stocks have been the highest-profile outlet for bullish AI industry impulses this year, and notable comments from Huang could put the wind back in their sails after they had slowed in recent weeks.

Of course, there are also other things happening in the sector, such as Micron’s announcement Sunday that it completed an acquisition of a new manufacturing site in Taiwan.

Either way, memory stocks are pushing higher after having exhaled a bit lately.
