THREAD: What are some Posting Traders doing, and what do the federal securities laws say about it? A securities law professor tries to make it simple.

(Tl;dr? Some people on the Internet will be surprised when the SEC investigates them for market manipulation.)

 Backstory: what's going on? GameStop sells video games (you've maybe seen their stores in strip malls). Its business model hasn't been doing so hot.

It's a public company, so you could go on your broker's website and trade its stock. Its price had been low for a while.
One very simple way to think about stock investing is that you can make two main types of bets: that a stock's price will go up, or go down.

Some big hedge funds (think BILLIONS) were betting that it'd go down. This is called a "short" bet.
The goal of a short sale is to sell high, buy low, and pocket the difference. Suppose you pay a small rental fee to borrow a stock, sell, and hope to rebuy it later at a lower price when you've said you'll give it back to the lender.

Note for later: "borrowing" is important.
The other kind of bet is a "long" sale, in which you buy a stock for its income (dividends) or the possibility of selling it for a higher price later (capital gains).

Compared with someone "short," someone "long" a stock actually has it (kinda).
In general, short sales tend to be made by sophisticated and wealthy investors, not mom-and-pop traders.

Shorting is controversial; it puts downward pressure on stock price. Long investors, big (Elon Musk) and small (mom and pop) alike, don't want to lose from low stock prices.
Some of them post on Reddit, where there's a community of people who talk about investing. Some members made some waves early last year for making big waves in the prices of stocks through coordinated buying and selling.

https://t.co/abvqutbusN
The posters settled on a particular strategy. We talked about long and short, but there's another kind of bet.

Instead of buying or selling the stock, you can buy options—also bets on a stock price going up or down—more cheaply from a big financial institution middleman.
Those big institutions don't actually want to be on the other side of your bet, so they will hedge their risk. If you bet the stock will go up, they might buy the stock to help fund your payout if you win.
This might put upward pressure on stock price. So one strategy the Reddit posters have adopted is to buy call options (bets that the stock will go up) at higher and higher target prices.
But then it occurred to someone that pushing stock prices higher in this way might be a way to get back at (or take money from) the hedge funds that were making "short" bets.
When you make a short bet, you're selling something borrowed. So you have to put up collateral, or "margin," just like on other kinds of loans.

If the price goes up, it eats away at the collateral available to cover the bet if it goes bad. So you have to put up more collateral.
A long investor can lose up to the amount of their initial investment if asset value goes to 0.

But because stock prices are theoretically limitless, a short investor faces potentially unlimited losses from a bad bet, if the price at which they buy back the stock skyrockets.
It's more technical than I want to get into in this thread (heck yeah #RegSHO) but let's just say it gets harder, and more expensive, to keep a short sale going the more volatile the stock's price gets.
There's information out there, if you know where to look, about which companies have a lot of short sellers. GameStop was one of them.

In fact, for GameStop there are more shares sold short than there are available to be bought back. So those holding the stock can sell.
So here's the strategy with GameStop:
1. Buy options to raise stock price.
2. Higher price forces short sellers to put up more margin.
3. Shorts also have to "cover" by buying back at much higher prices.
4. You sell to them at the high price.
5. Maybe destroy hedge fund?
As @matt_levine wrote today, as a theory of how to profit from this strategy, it "is, uh, not wrong?"

Seems to have worked in the case of Melvin Capital, a hedge fund that had to "cover" its short position and get bailed out by other rich people. (Follow Matt if not already.)
This is maybe good, and maybe bad. Maybe you like the David vs. Goliath story. Maybe you think short sellers are bad. Maybe you think it exposes the hypocrisy of modern markets.

But I'm here to talk about federal securities law. (I'm not a NE lawyer and this isn't legal advice.)
https://t.co/RFsx8eGYVJ

The SEC yesterday announced it was aware of all this and is "review[ing] the activities of regulated entities, financial intermediaries, and other market participants."

That last group includes everyone I talked about above short sellers, posters, all.
You might ask how the posters could be in trouble. One way: it fits a rough pattern that securities regulators often go after for fraud, the "pump and dump" scheme. That's an easy mental model to fit the case into. But is it fraud if you're announcing it?

https://t.co/9KSUhIwXAN
Securities regulators have tools beyond "fraud" at their disposal to get at other objectionable market practices. One such tool is Section 9 of the '34 Act, which prohibits manipulation. The SEC once called it "the very heart" of the act. https://t.co/B2amYvRAX7
Section 9(a)(2) makes it illegal to raise the price of a stock "for the purpose of inducing the purchase ... of such security by others."

Sound familiar? Look again above at GameStop "strategy" steps 1-4. Can posts show that "purpose"?

https://t.co/O8qIHXzJ2T
I don't mean to suggest traders have violated § 9(a)(2) (def isn't legal advice).

But the SEC is undoubtedly looking into it.

Maybe it is or isn't a winning theory. But putting it to the test is costly. The SEC typically has leverage to get its targets to settle.
As @ProfFletcher noted in a recent @DukeLawJournal article, "the SEC has not made much use of this provision." Maybe that'll change soon.

(The rest of her article, about open market manipulation, is great and worth reading!)

https://t.co/NsxRo3GuVk
There are lots of aspects to this captivating story that I haven't mentioned.

But on another level, it highlights securities law's weirdness. Our law has long taken an inconsistently skeptical view of market manipulation. Why are some practices allowed, others not?

Some observations and thoughts on ZILSwap: What went well, its impact on the $ZIL ecosystem and where we need to improve with some concrete plans that are being worked on. A thread:

👇

1/ ZILSwap was launched by @SwitcheoNetwork on Oct 5, 2020 (~2 months old). Soon after, we noticed for the first time, a flurry of ZRC-2 tokens (equiv. of ERC20s on $ZIL) getting launched on the network (even though the fungible token standard had been around for a while).

2/ The ability to provide a marketplace for people to exchange tokens was the trigger for deveopers to start issuing tokens and developing a token economy. In fact, there was a token for which, the entire supply was put on a ZILSwap pool w/o any team withholding.

3/ This was an extreme example of why a DEX was needed and the role it played in bootstrapping several tokens and respective token economies. Over 25 tokens are available on ZILSwap in the form of liquidity pools. The total pool size across all tokens is over USD 1 million.

4/ ZILSwap also made it possible for the first time for anyone to get access to $XSGD (the Singapore Dollar Stablecoin issued by @xfers). In fact $XSGD and $gZIL contribute the greatest proportion of the total pool.

So, what do you have to do to get CLARITY in your Trading-

Find one style that is suitable to your personality and double down on it.

Why?

As a former professional poker player, I'm very clear about the importance of psychology in investing/trading.

You can have a very solid strategy, but if the mental aspect fails, everything fails, no matter how good you are.

Thread 👇

In this thread I will briefly describe the most important aspects of trading psychology, and give some simple tips to try to improve them.

It's good to always be aware of these aspects, to be able to detect them and act in time.

1) FEAR

This is one of the most important. It can make you get out of a position at the wrong time.

One of the main reasons you can have fear is because you are putting more at risk than you are willing to lose.

Tip: reduce the size of your position until you are comfortable.

2) GREED

Greed can be even worse than fear. It leads you to be overpositioned and to destroy your average entry.

Tip: learn to conform to what you have. Practice gratitude for everything that comes your way. Remember that the most important thing is to stay in the game.

3) TILT

This is well known in poker. There are many reasons why tilt can appear (downswings, injustice, mistakes...)

Tilt takes you away from your perfect strategy. From your A game.

After a losing streak you may think that the market is being unfair to you.

Pyramiding 2.0

A thread-


What is pyramiding?

It is simply adding to your winners.

Why use pyramiding?

1. It makes your winners bigger than your losers.

• Because you are adding positions when your trades are going your way, you are increasing your gains but your losers will be small comparatively.

2. You lose less during Draw-down time ( it saves you from losing big during whipsaws )

• Many times when the market is in sideways mode, Entering a trade with full risk might not be the best idea.

• So, you test the waters with a small position first, it could be ⅓ or ¼ of your total risk.

• So if the Breakout fails or whipsaws come, then you will only lose a small part of your overall risk.

• Then when position starts to go in your favor you can add to it.

3. It helps you to concentrate on a few trades,

They say that don’t put all your eggs in one basket, but don’t put them in too many either.

• See, Everyone can see charts and find breakouts, pullbacks etc.

THE EVOLUTION OF OUR NATIONAL FLAG (1857-1947)

The INDIAN NATIONAL FLAG is not just a flag! It's a testimony of patriotism and seamless sacrifice. A symbol representing one of the oldest civilizations on this planet.

Let's hope what happened yesterday never repeats!

(Thread)


After the revolt of 1857, the first Indian flag was designed. The design was based on western heraldic standards with "Union Jack" in the upper-left quadrant and a "Star of India" enclosed in the royal crown in the middle of the right half.(1)


The flag was a symbol of the direct imperial rule in India.(2)

In 1904 the first Indian flag which stood for India's independence from the British was devised. The design was provided by sister Nivedita, an Irish disciple of Swami Vivekananda.(3)


The flag was red and yellow with an image 'Vajra' (weapon of god Indra). The phrase 'Vande Mataram' was written in Bengali on it. The red colour and the yellow colour signified freedom and victory while the symbol of vajra stood for strength.(4)

Published a new essay: The red flags and magic numbers that investors look for in your startup’s metrics – 80 slide deck included!


This was a deck that I created on my (longish) interview process with @a16z. It was a long path, starting with meeting folks at the firm 10 years ago. But the purpose of the deck was to explain how I would use my superpower in an investing context

Here's what I explain in the deck. As investors (whether angel or VC) we're often confronted with an up-and-to-the-right graph. Is it going to go up? Or down?


One solution to forecast these growth curves is the Growth Accounting Framework, where you add up New+Reactivated and subtract churned users. In each time period that gives you the difference in monthly actives.


The problem with this is that it's a lagging metric, not a leading one. We need to go one level deeper and look at the underlying loops that drive these numbers, to understand the quality.

THE BATTLE OF PRATAPGARH (10 Nov, 1659)

Chhatrapati Shivaji Maharaj's impeccable military genius and matchless courage humbled the Adil Shahi Sultanate.

The beginning of what was to come later for the M0ghuls from one of the most indefatigable defenders of Dharma!

(Thread)


Shivaji’s growing influence in Maval region, made him a threat to the Adil Shahi ruler of Bijapur who sought to restrain him. The man who was given the responsibility of this mission, was their commander, Afzal Khan. Afzal was a formidable warrior known for his ruthlessness.(1)

His strategy was to bring Shivaji out into the plains, where he held an advantage, compared to the rocky Deccan terrain. Afzal attacked the holy town of Pandharpur, and later demolished the temple of Bhavani at Tuljapur to instigate Shivaji in a bid to bring him out.(2)

Shivaji was angry but remained patient. Knowing that he could not defeat Bijapuri Sultanate in an open battle, Shivaji moved to Pratapgarh fort, located on rocky heights, surrounded by thick forests of Jawali.(3)

This set the pattern for future Maratha attacks, using guerrilla warfare against larger invading armies rendering them ineffective in unfavorable terrain.(4)

Butt plugs were originally sold as a miracle cure for headaches, acne, and insanity

Thread, article here and h/t: @qikipedia :
https://t.co/Ts84xnmWKJ


For a long time, medicine was pre-occupied with the question "can this be solved by putting something in the butt?"

Take, for example, tobacco smoke enemas, in which 18th Century physicians saw drowning victims and attempted to de-deadify them by blowing tobacco smoke up their rectums with a pipe.


Despite having no medical benefit whatsoever, the practice was popular, and enema kits lined the Thames like lifebelts, ready to be used as one final humiliation for somebody who was crap at swimming.

This practice ended sometime after 1800 when it became apparent that it didn't really work, given how the anus famously isn't really connected to the lungs, but doctors weren't quite finished with having a poke around in the old anus to see what happens just yet.
