THREAD: Robinhood and other brokerages came under fire last week for restricting trading in certain securities, including $GME and $AMC.

A thread simplifying the underlying mechanics of this drama and explaining why our archaic T+2 settlement system is to blame...


1/ First, if you're unfamiliar with the backdrop to this story, here are the basics.

GameStop (and other "meme stocks") saw a massive price spike last week.

There were fundamental and technical reasons for the rise.

My thread below is a helpful primer.


2/ On Thursday, several brokerages, including the popular @RobinhoodApp, halted or restricted trading in many of these stocks.

The public outcry was immediate (and very loud).

Amazingly, it even had @AOC and @TedCruz agreeing on something.


3/ There was speculation suggesting that Robinhood was involved in something nefarious.

Many pointed to their relationship with Citadel - a buyer of Robinhood order flow and a part-owner of infamous $GME short Melvin Capital - as a potential driver of the trading halts.


4/ But while this story made for headline-grabbing news, the real driver of the trading halts was much more mundane.

It has to do with our financial system's archaic "T+2 settlement" infrastructure.

It can get a bit complex, so let's simplify it here for everyone to understand.
Barry Diller has built one of the most unique businesses in the world.

IAC is an "anti-conglomerate" — a combination of companies meant to split apart. Over the years, that's included $EXPE, $MATCH, $TREE and others.

This is his playbook

First, a little history.

Diller started out in the mailroom of William Morris after dropping out of UCLA. He rose through the ranks, serving as the assistant to legendary exec Elton Rule.

One of Diller's innovations was the "ABC Movie of the Week," the made-for-TV movie.

Over time, Diller established himself as a force in the traditional entertainment industry.

He served as CEO of Paramount, producing hits like 'Taxi,' 'Grease,' and 'Indiana Jones.'

As CEO of Fox, he greenlit 'The Simpsons.' Mr Burn's appearance was based on Diller.

In 1992, Diller decided it was time for a change. He knew the media industry was changing and wanted to be a part of its future.

Diller believed entertainment would be mediated by computer screens. h/t @modestproposal1

His great revelation came thanks to future wife, Diane von Fustenberg.

She visited the headquarters of "Quality, Value, Convenience" in PA and watched as soap-opera star Susan Lucci sold $450K of haircare products in an hour.

She told Barry he had to see it for himself.
