Seven Guys Named Vinnie

Added on by C. Maoxian.

This is a fun excerpt (with my edits) from this conversation between Barry Ritholtz and Chris Davis:

Davis: “I met Charlie [Munger] long before Warren [Buffett]. The reason was I was trying to sell a business. My grandfather, as I started going through his accounts and going in there on the weekends, he had a business called Securities Lending. And I don't know how well you know that business.”

Ritholtz: “Any time you're going to short a stock, you need to borrow from somebody and it's going to cost you a little.”

Davis: “It's going to cost you a little margin. So my grandfather's view was he had a portfolio of appreciated stocks that he was never going to sell. And he said if somebody wants to short the stock and pay me to borrow it, fine. And the number one borrowed stock in those days was Berkshire Hathaway, of course, because you couldn't borrow it anywhere because everybody had the certificates.”

Ritholtz: “They literally had the paper certificates.”

Davis: “Yeah, there was very little Berkshire that was in street name and it was an individual people and therefore you couldn’t borrow it.”

Ritholtz: “It was locked away and safe.”

Davis: “Yeah. So he had a big holding and he had a broker-dealer, Shelby Cullom Davis was a registered broker-dealer [CRD #767]. And so he could lend out the shares and make a couple hundred basis points a year extra return on top of the Berkshire return. So that's how he started in the securities lending business.

But gradually the guy who was doing it for him and administering it said, wow, you know, we can also help. We've got all these people that want to short all sorts of different securities, and we can act as what was called a broker finder. We'll go out and find the securities for these people to short, and we'll make a little, a little spread as they go through. Well, this business grew and grew and grew. And soon there were, you know, 17 employees in this securities lending business. And it was a big operation.

And my grandfather by then was, you know, probably in his 80s and was nervous because, you know, as I went through the list of counterparties with him, there were firms we had never heard of. There was this one called LTCM and I said, what is this LTCM, we've got like, you know, $500 million … $800 million lent out to them. What? Oh, that's Long Term Capital Management. So we talked about it. He said, yeah, I think we gotta get rid of this thing.

And he said, fine, well, see if you can find somebody to take it over, because we do have 17 employees and they made their careers here. We're not going to fire everybody. And so we started calling around and I thought, what characteristics do we need? We need a lot of excess capital, someone who holds ideally an appreciated portfolio of securities, you know, sort of a triple A type balance sheet. And somebody that can understand. So I thought, well, Berkshire.

So, a wonderful friend in those days named Bob Lenzner was a reporter at Forbes. Our kids were in the same elementary school. And I got to know him. Just, you know, watching basketball games for third graders or something, and I heard his name around and he said, he mentioned casually in the conversation that he had met this brilliant guy, Charlie Munger.

And I said, well, I know who Charlie is, but I'm dying to meet him. And so Bob arranged for us to have breakfast, and Charlie was in New York and I went down, it was at the Millennium Hotel, down by the World Trade Center. And I went down and I sat down and introduced myself to Mr. Munger. Pleased to meet you. I'm Chris Davis, and I said, you know, I'm working with my grandfather. Shelby Cullom Davis & Company. And have I got a business for you? And I pitched our securities lending business, and Charlie put up his hand after about four minutes and he said:

‘I have no intention of buying a business run by seven guys named Vinnie.’

And Barry, it was the perfect description. We had Vinnie, Tony, Mikey, Nicky. And so we did end up finding a buyer eventually. And it wasn't really a buyer. We just did sort of an earn-out. We just wanted everybody … we just wanted them to have jobs. And so they all got a job at a broker-dealer.”


As someone who pays hundreds of thousands of dollars every year for “locates” to a mysterious, opaque “lending pool,” I too found this story very funny.

Nasdaq FINALLY Responds to Obvious Market Manipulation

Added on by C. Maoxian.

Once again the criminal manipulators sent a stock (ENSC this time) up 4,000%+ in seconds this morning… this form of manipulation creates systemic risk and needs to be vigorously policed. The same plot was hatched in CIIT and PLYX earlier this year, and the Nasdaq did nothing about those.

We can only suspect that someone with serious “pull” was hurt this time around, which caused the Nasdaq to act and finally protect investors’ interests by cancelling all trades that occurred above $0.5846 that were executed between 5:47:00.000 and 5:48:00.000 ET.

SEC Rule 606 Reports for All Day Trading Brokers

Added on by C. Maoxian.

“Securities and Exchange Commission Rule 606 of Regulation NMS requires all broker-dealers to make publicly available a quarterly report with regard to their order routing practices for non-directed orders. The Rule excludes from the quarterly report those orders that are directed by a customer to a particular exchange or market for execution.

“Certain venues that brokerage firms route orders to, such as exchanges, charge execution fees or provide rebates based upon whether routed orders take liquidity from, or provide liquidity to, the venue. In addition, certain venues, including exchanges, have various volume-based tiered pricing/payment schedules pursuant to which brokerage firms may receive incremental pricing benefits based upon the aggregate trading volume routed to the venue (including volume not associated with customer orders).”

Worst Adverse Excursions in February 2026

Added on by C. Maoxian.

February was an amazing month for the blind shorts, with next to no outlier losses and hundreds and hundreds of winning trades. There was one extreme outlier, PLYX, that we’ll look closer at below.

Don’t forget to look at the outlier moves in October 2025 (23), November 2025 (5), December 2025 (6), and January 2026 (10).

February 2: ROMA (Hong Kong) … note lucky number $8.88 high … the scammers know that they can act with impunity under the current US administration, so they have some fun manipulating to precise prices.

February 3: NPT (China)

February 11: NCI (Hong Kong)

February 13: RIME (USA)

February 17: OLB (USA), OBAI (USA), PLYX (USA)

PLYX hit a pre-market high of $66 after “dinging” at $3 or $4. The ~1,500% move took ten seconds. This was a disaster for anyone whose bot employs aggressive chase logic to exit in the pre-market.

Below is the one second price chart for PLYX. Unfortunately I was at the screens when this happened and saw it squeeze in real time, which was not good for my pulmonary pig valve. PLYX closed the day at $4.02.

February 26: AEHL (China)

Broad Concerns about Confidence in Our Securities Markets and Market Integrity

Added on by C. Maoxian.

Jeffrey Starr of Charles Schwab wrote a good comment letter to the SEC which you should read in its entirety. I’ve excerpted some key parts below:

“Large reverse splits tend to be clear indicators of potential fraud, yet Nasdaq has not been vigilant in policing this type of behavior … Many of these microcap securities are nexuses for major fraud – pump and dump schemes often orchestrated by company insiders. Many of the microcap securities in question are for shell companies from the Cayman Islands and British Virgin Islands orchestrated by fraudsters often, but not always, located in China.”

“Exchanges such as Nasdaq are not properly policing existing listing standards and have overly lenient rules that allow fraudulent firms to stay listed for much too long, allowing the fraud to snowball.”

I’ve been saying this for years, but I guess I should have contacted the SEC directly instead of tweeting into the void.
