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.

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.

Kenvue plunges after reports suggest RFK Jr. may try to link prenatal Tylenol use to autism

Kenvue sank 15% Friday after a WSJ report said Health and Human Services Secretary Robert F. Kennedy Jr. may attempt to link prenatal Tylenol use to autism in an upcoming government report.

Kenvue, the maker of Tylenol and formerly a division of Johnson & Johnson prior to a 2023 spin-out, pushed back, saying the science shows “no causal link” between acetaminophen use during pregnancy and autism, and pointed to FDA and medical groups that agree on the drug’s safety.

The FDA itself has found no “clear evidence” of harm but advises pregnant women to consult providers before taking OTC meds.

The report is also expected to float a folate-derived therapy as a potential treatment.

Tylenol is just the latest well-established medication to face scrutiny under Kennedy, who has already stirred controversy by reshaping vaccine policy and amplifying doubts about mRNA shots.

Kenvue shares are now down over 18% year-to-date.

Lucid surges following 6 days of losses after headlines misidentify Cantor Fitzgerald’s lower split-adjusted price target as a good thing

It’s been a shortened week, but still a rough one for Lucid. Investor blowback to the luxury EV maker’s 1-for-10 reverse stock split has sent shares to all time lows this week.

After six straight days of closing lower, Wall Street appears to have decided enough is enough and is loading up on Lucid shares on Friday, sending them up 13% in recent trading. As of 2:10pm eastern, Lucid trading volumes were at more than 240% of their 30 day average.

Some of the move could be attributed to traders reading headlines that don’t take into consideration Lucid’s reverse split. Cantor Fitzgerald on Friday slapped a new price target on Lucid of $20, compared to its previous target of $3. Some news outlets (not us!) presented that as an increase. The problem: With the 1-for-10 reverse split in effect, a comparable price target would have been $30. The new $20 target is actually... a cut.
