Cornering the Market

Cornering the market is a deliberate, and highly illegal, strategy where an individual or a group of colluding investors acquires such a dominant share of a particular asset, commodity, or security that they can effectively control its supply and, consequently, its price. Imagine trying to collect every single copy of a rare comic book. Once you own them all, you become the sole seller, and you can demand an astronomical price from anyone who desperately wants one. In the financial world, cornering the market works on a much larger scale, aiming to create an artificial shortage to force prices sky-high. This is not investing; it's pure market manipulation. The goal is to create a “squeeze” on other market participants, particularly those who have bet on the price falling, forcing them to buy from the cornerer at an inflated, dictated price.

The classic cornering scheme is a two-pronged attack that targets both the physical asset and its derivatives market. The manipulator, or “cornerer,” quietly accumulates a massive position in the physical asset itself—be it tons of copper, bushels of wheat, or shares of a company's stock. At the same time, they often buy a huge number of futures contracts, which are agreements to buy the asset at a future date for a set price. The trap is sprung on short sellers. These are traders who have sold futures contracts without actually owning the underlying asset, betting that its price will fall by the delivery date. When that date arrives, they are legally obligated to deliver the physical commodity. But there's a problem: the cornerer has bought up almost all the available supply! The short sellers are trapped. Their only option is to buy the asset from the one entity that holds it: the cornerer. This creates a panic, known as a short squeeze, driving the price to extreme levels and allowing the manipulator to sell their holdings for enormous profits.

Absolutely not. Cornering the market is a textbook example of market manipulation and is strictly illegal in most jurisdictions, including the United States and Europe. Regulatory bodies like the SEC (Securities and Exchange Commission) in the U.S. and the ESMA (European Securities and Markets Authority) in Europe have broad powers to prevent and prosecute such activities. The reason is simple: cornering destroys the principle of a free and fair market, where prices are set by genuine supply and demand. It creates artificial volatility, harms consumers and businesses who rely on stable commodity prices, and can cause catastrophic losses for unsuspecting investors. Those caught attempting to corner a market face severe penalties, including massive fines, disgorgement of ill-gotten gains, and prison sentences.

History is filled with cautionary tales of ambitious traders who tried to bend markets to their will—and often failed spectacularly.

Perhaps the most infamous example, brothers Nelson Bunker Hunt and William Herbert Hunt attempted to corner the global silver market. Believing that inflation would devalue paper currency, they began stockpiling immense quantities of physical silver and silver futures. Their buying spree drove the price from around $6 per ounce in early 1979 to a peak of nearly $50 per ounce in January 1980. However, their scheme unraveled when regulators and exchanges, alarmed by the manipulation, changed the rules. They imposed trading restrictions and drastically increased margin requirements, forcing the Hunts to post more cash to maintain their positions. They couldn't, leading to a forced liquidation and a massive price crash on “Silver Thursday,” March 27, 1980. The Hunts were bankrupted and faced years of legal battles.

In a more modern and complex case, Porsche executed what became one of the biggest short squeezes in history. Over several years, Porsche secretly used options to build up a position that gave it control of roughly 74% of Volkswagen AG's voting shares. At the time, many hedge funds had heavily shorted VW stock, believing it was overvalued. In October 2008, Porsche shocked the market by revealing its stake. The short sellers panicked, realizing there weren't enough freely traded shares (the float) available for them to buy to cover their positions. The frantic buying sent VW's stock price soaring over 400% in two days, briefly making it the most valuable company in the world. While not a traditional commodity corner, it demonstrates how controlling a majority of an asset's supply can create a devastating squeeze.

For a value investor, the concept of cornering the market is the antithesis of a sound investment philosophy. Value investing is not about manipulating prices; it is about discovering prices.

• Focus on Intrinsic Value: A value investor's job is to analyze a business, estimate its intrinsic value, and buy its stock for a significantly lower price (a margin of safety). The profit comes from the market eventually recognizing the company's true worth, not from artificially creating a buying frenzy.
• Avoid Speculation: Cornering schemes are pure speculation. They are high-stakes gambles that depend on outsmarting regulators and other market participants, not on the underlying performance of a business. This is a game that even the incredibly wealthy Hunt brothers ultimately lost.
• Long-Term Partnership: When you buy a stock, you should see yourself as a part-owner of a business. Your goal is to benefit from the company's long-term success, its earnings, and its growth. Market corners are short-term, destructive events that have nothing to do with building wealth through business ownership.

In short, stay away. Whether you are tempted to participate in such a scheme or find yourself holding a stock that is being squeezed, the risk of a catastrophic loss is immense. True investment success is built on patience, discipline, and a deep understanding of business fundamentals, not on market games.
