Was GameStop's Rise Actually Orchestrated By Hedge Funds? (washingtonmonthly.com) 121

Robert J. Shapiro advised senior members of the Obama administration on economic policy, and served as an Under Secretary of Commerce under Bill Clinton.

Now a senior fellow at the McDonough School of Business at Georgetown, he's suspicious of the surge in GameStop's stock price: Allegedly, this is the tale of scrappy, small online day traders buying shares of a beleaguered company to thwart a hedge fund scheme to take it down... Yet, certain facts are publicly available, including GameStop's daily trading volume, its daily prices, the number of short sales of its stock, and how many shares are held by big institutional players. Those facts suggest that the Reddit online traders have been on the sidelines of a trading war among a handful of big institutional investors. The SEC should subpoena the records because the hard data also suggest that some big players may be using trading strategies used in the past to manipulate stock prices...

Unless most of the Reddit bunch have assets in the top one-tenth of one percent of Americans, they were mere bystanders to last week's trading of 682 million shares at an average price of $218.20 — purchases totaling nearly $150 billion in a wildly volatile market. Only institutional investors have such resources to trade stocks, not self-styled populists with Robinhood on their iPhones. Since most big players are regulated public corporations with fiduciary responsibilities to avoid the enormous risks involved in this high-stakes game of chicken, the GameStop players almost certainly are all lightly regulated hedge funds. The trading volume and price gyrations also suggest that those hedge funds may be manipulating the market...

[S]ome 20 million or more of the GameStop shorts were never borrowed and never delivered to their buyers. They were what the SEC calls "naked shorts." The SEC has banned naked shorting as abusive market manipulation because large-scale naked shorting artificially drives down a stock's price. Given the volume of short sales and overall trading in GameStop, large-scale naked short-selling was clearly involved when GameStop's share price fell $153 last Wednesday (from $347 to $194) and again this Monday when the price plummeted from $325 to $225... The data also suggest a bigger story of possible manipulation involving the huge increases in GameStop's share price. The wild swings in those share prices reflect hundreds of millions of shares being traded each day, mostly in big blocks and presumably from one hedge fund to another. When the price rose, one fund got out and took huge profits while another bought in, expecting the price to rise further, and yet another sold short, expecting the price to fall...

In effect, hedge funds may have manipulated GameStop in opposite directions, wringing out profits daily or even two or three times a day. If this is correct, the GameStop saga is not some populist uprising but a rolling version of "pump and dump," a classic form of manipulation and naked shorting.

        They know exactly what they're doing - nothing and deliberately so. The SEC are not investigating their rich pals, nudge nudge wink wink, because they want to be paid huge sums themselves when they walk through the revolving doors.

But honestly, whenever the SEC came to review my software and the company's record keeping I felt like if I'd wanted to I could have told them anything and they'd believe it. I can't say it's entirely their fault for being so gullible, but I was shocked that they seemed shocked at us not obfuscating our transactions.

          There are systems at the SEC and your competitors to corroborate your story. You guys have your private book but the public ledger has to match up to what you say.

          Then there is the fact of just how much of a influencer you are on the general market. Finally, even if you influence the market, if you are doing it at the benefit of the general holders, it's considered a good thing*.

          It's all a risk assessment. You don't spend as much time on smaller funds, smaller stocks, entities with good history, normal success, or highly spread out exposure. This is true for all forms of QC and audits; from your toothbrush, CPU, to parts on satellites.

          Granted there were plenty of places where the SEC messed up. Worldcom, Enron, L3, etc.

          * = good thing has to do more with information transport and transparency than moving a security in a specific direction. Shorting, like all legal trades, are considered good as it provides a valid opinion on the valuation of a security.

        • I've always sought to comply with both the letter of the law and the spirit.

          Note that complying with the spirit of the law may leave you in serious trouble if and when things go south. The courts (and the lawyers) observe the LETTER OF THE LAW. The spirit is meaningless to a lawyer or judge....

      • The policy didn't work because, apparently, the penalties are not stiff enough. The punishment for failure to deliver is to lose your ability to short plus (sometimes) a small fee. For the types of profits that would have been reaped, it very well may be worth paying the failure-to-deliver penalty.
        • You also lose any profits of those transactions. And losing that reputation really hurts because the system is based on everyone being honest within the rule set. People will not lend to you or raise interest rates or leave you out in partnerships.

          • Are you sure about this? I'm not aware of those types of penalties being imposed.
            • Disgorgement. Many times used in shorting cases.

              The SCOTUS recently limited this power. Haven't read the full details (if anyone did, please educate me) but basically they said funds that don't go back to those hurt are equal to fines rather than equivalent to restitution.

              Seems fine at first but that means it gives the wrong doers more wiggle room. They already negotiate the fees, sentencing limits, and restitutions anyway. Big firms with good lawyers are now more empower. Before, the SEC could take all pro

        The author assumes "some 20 million or more of the GameStop shorts were never borrowed and never delivered to their buyers" because there were "15 million more shares allegedly borrowed than existed in the entire market".

        He is not taking into consideration that the same shares can be borrowed and sold short multiple times. This article from nearly a year ago, about TSLA and GME shorting, covers it well: https://www.nasdaq.com/article... [nasdaq.com]

        "A stock that's sold 100% short seems to defy logic, but it is technically possible due to how short-selling works.

        Short-selling involves borrowing shares from someone who owns it, selling them, and waiting to buy those shares back at a lower price.

        Here's the quirk: shares can be lent more than once. If a short-seller borrows shares from one brokerage and sells to another brokerage, the second brokerage could then lend those shares to another short-seller. This results in the same shares counted twice as "shares sold short."

        Many of GameStop's shorted shares may have been borrowed, sold, and borrowed again, producing the 100.6% ratio of shorts to shares outstanding.

        This rarely happens, but it has happened before."

        • Those same people think fractional reserve banking (which is the same concept and math) is banks "printing money out of thin air"

          He is not taking into consideration that the same shares can be borrowed and sold short multiple times.

          Indeed. To actually get a sense for problems with shorts in a name, one needs to look at failures to deliver, conveniently tracked on the SEC website [sec.gov], though not published in realtime. Data for the recent action in meme stocks is not yet available.

          If you see a name with a high proportion of its shorts failing to deliver, then there is something to talk about. To check, one has to combine this dataset with a short interest dataset.

        The SEC's job is to contain some of the market volatility from affecting the broader market and the little guy, but they give pretty free reign to wealthy people to take the risks they want. Who's getting hurt in this?

In theory you haven't lost money if you bought at $100 and haven't sold yet, but you also haven't made money if you bought at $40 and haven't sold yet either. Based on the volumes of trades when the stock was well over $100 there must have been at least a few billion in realised and unrealised losses by now (matched by a few bil

      Big funds didn't start the wave, but for sure they surfed on it.

      Some got caught in the squeeze, others surfed on it. If there was any way I could have bet that "Gamestop is going to be significantly lower than 400 USD per stock in 6 months", I probably would. have done it. Because while knowing the price in the short term was hard, long term I see it as a failing business as the market evolves towards and no-one sane would say that the underlying long term value of the stock was within an order of magnitude of 400 USD.

  • They just like the stock (and realized it was cheap and naked shorted to a hilarious level so they assfucked it because LMAO). Don't believe fake news when it comes to anything relating to stocks, people will vomit all sorts of lies to control the market.

    People who actually trade have strict definitions for terms. For example they distinguish between selling shares short, buying puts, selling calls. They are all bear bets. But first one is a sale of security without any expiry date. As long as you have the collateral including margin, and the willingness to pay the fees, you can keep it open and try to ride out the storm. The last two are option trades, with a definite end date. Buyer of option have limited down side potential, max they can lose is the cost of the options they bought. Sellers of call options have theoretically unlimited down sides. Sellers of put option have a very large but finite down side.

    SEC defines naked shorting as selling a share without borrowing it. It is illegal. People casually conflate this with selling call options without a hedge to limit the down side potential. That is hedging, not naked shorting.

    The gamma instability seems to be systemic. People buy deep out of money calls far into the future. The market maker calculates the odds and prices the call based on the well known security pricing formula. Once sold, anytime the price of the stock increases, (delta), the seller (writer in their parlance) needs to buy a few more shares because the odds of the call getting assigned has increased. This act of the broker buying the share increases the price of the share, (gamma), triggering another round of buying by the people who wrote the calls. Usually each of the delta, gamma(delta), delta(gamma(delta)) recursion diminishes and vanishes eventually.

    But, when the time duration is very large, and if the strike price is very very deeply out of money, there could be an instability, and the sequence, delta1; gamma1=gamma(delta1); delta2 = delta(gamma1), delta2 >= delta1 happens. Then all hell breaks loose. The positive reinforcement has no real limit, the price can increase exponentially, due to high frequency trading before there could be any intervention.

    This seems to have happened to Tesla. And then to Gamestop.

    Caveat: I am not a trader. This is my understanding of random reading from reddit and tweets from S3 partners https://twitter.com/ihors3 [twitter.com] and reflex research https://twitter.com/ReflexFund... [twitter.com] It is very likely I have misunderstood or missed some key factors in the narrative I have constructed to make sense of what I saw.

    • I'm not a trader but I think much of this is accurate or at least options pricing is. I don't think that anybody who write deep out of the money calls is going to go and purchase shares as long as those calls are way out of the money. The writer might have some stop-limit mechanism to purchase shares in order to, well, limit their losses. But not necessarily. They may have a call-spread where they use the proceeds from the calls they wrote to purchase even-more out-of-the-money calls. This limits their

This limits their losses and they are still guaranteed a profit as long as the stock doesn't end between the two prices. But even then they may be able to profit by closing out the position and having benefited from the time decay.

        The sellers may well have hedged, but it's hard to measure. Let me explain...

        The call writer is likely an options market maker (e.g. Peak6). They will have done much more options trading in GME than just writing a single set of calls. Whoever is responsible for maintaining the GME options book will aggregate the delta of those written calls along with all other positions resulting from GME option trades. Generally they will then trade shares sufficient to keep the total delta within some reasonable boun

        • Thank you. If I understand you right, it is not a systemic risk, the call writers are aware of the possibility and have standard procedures to handle it. They probably mismanaged GME, or probably blindsided by the speed of movement.

          Feeling a little relieved.

            Yes, the term of art for this is "gap risk". There are even stochastic option-pricing models that explicitly include price jumps, and for option that are close to expiration they can be useful in distinguishing "hedgeable" delta from jumps in stock price that cannot be hedged in the way Black-Scholes likes to assume.

        • Yes this all makes sense to me. But where I am going to struggle a bit is that, it seems, that writing a far-out-of-the-money call doesn't contribute much delta. The delta tends to come from near-the-money positions? Is that correct? The OP indicates that the call writer has to buy shares based on price movement. You point out that, strictly, they don't have to do so and that the hedging costs them money but that is probably splitting hairs. This would seem to be especially true if they have written o

            The highest-delta positions are in-the-money options. However, those have small "gamma", so the size of necessary hedge does not move with price very much. Far out-of-the-money options have both small delta and small gamma.

            ...do options market makers have to trade the way that the market makers in actual stocks have to have a bid/ask?

            Not really, though you will find many are registered market makers for the underlying stocks, with the associated quoting obligations in the stock.

            And if they were selling way more calls than puts, wouldn't then adjust their price on the calls?

            Oh absolutely. This will have been built into the company's automated options quoting systems, generally by adjusting the implied vol curv

  • That is assuming that the Reddit group doesnâ(TM)t have large numbers of professional traders to begin with.

  • Rich and poor do not play the same game, even though they seem to be hanging in at the same arena.

    When a poor guy loses, they go bankrupt. When a rich guy loses he is "bailed out".
    Even when the poor guy was finally bailed out (2007 mortgage crisis), the big guy was taken along with the ride, and actually got largest bail outs.

    What was the saying: private gains, socialist loses. Something like that.

  • The people who'll most lost out from Gamestop (or similar ventures) will be the idiots who bought into this little pump and dump after it gained some publicity. The shortsellers weren't the enemy, people's own gullibility was.

    The rise and fall of GameStop was entirely predictable.

    First, viral posts on Reddit induce clueless small-time "investors" to buy GameStop stock, puffing up its value. There was never any way the value could stay sky high, it wasn't justified by the fundamentals of the business.

    Now why are we all shocked that the stock price has tanked?

    The same people who bought into the crazy buying binge, are probably the kind of people who would believe conspiracy theories, or make them up to cover their own silly mistakes.
