Short Squeeze

A Short Squeeze is a market scenario where a heavily shorted stock sees a sudden price surge, compelling short sellers to buy shares. Positive news or stop-loss triggers often cause this. It results in increased stock volatility and poses risks of overvaluation and losses for short sellers. Notable examples include the GameStop short squeeze in 2021 and Tesla’s historical short squeezes.

Defining a Short Squeeze

To understand a short squeeze, let’s break down the key components:

  1. Short Selling: Short selling is a trading strategy where an investor borrows shares of a security from a broker and sells them on the open market, with the intention of buying them back at a lower price in the future. The difference between the sale price and the buyback price represents the short seller’s profit.
  2. Short Interest: Short interest refers to the total number of shares of a security that have been sold short by investors. It is expressed as a percentage of the total outstanding shares of that security.
  3. Squeeze: A short squeeze occurs when the price of a security that has been sold short starts to rise significantly. As the price increases, short sellers may face mounting losses, and to limit their losses, they must buy back the shares they initially sold short. This buying pressure from short sellers can further drive up the price of the security, creating a feedback loop of rising prices.

Mechanics of a Short Squeeze

The mechanics of a short squeeze can be understood through the following steps:

  1. Short Selling: Short sellers borrow shares from a broker and sell them on the open market. They hope to repurchase the shares later at a lower price.
  2. Rising Prices: If the price of the security begins to rise due to various factors, such as positive news, strong buying interest, or a short-term supply shortage, short sellers may start to incur losses on their positions.
  3. Covering Short Positions: To limit their losses and close their positions, short sellers must buy back the shares they sold short. This buying activity adds upward pressure on the security’s price.
  4. Feedback Loop: As more short sellers rush to cover their positions by buying the security, the price continues to rise. This can trigger a chain reaction as other short sellers also cover their positions, further fueling the price surge.
  5. Panic Buying: In some cases, a short squeeze can lead to panic buying by both short sellers and other market participants who want to profit from the rising prices. This frenzy can drive the price to extraordinary levels.

Factors Contributing to Short Squeezes

Several factors can contribute to the occurrence of a short squeeze:

  1. High Short Interest: A security with a high level of short interest is more susceptible to a short squeeze. If a significant portion of a security’s total outstanding shares is sold short, there is greater potential for a short squeeze to occur.
  2. Positive News or Catalysts: Positive news or unexpected events related to a security can trigger a short squeeze. This may include strong earnings reports, favorable regulatory developments, or announcements of partnerships or acquisitions.
  3. Low Liquidity: Securities with low trading volumes and limited liquidity can be more susceptible to sharp price movements, making them prime candidates for short squeezes.
  4. Lack of Available Shares to Borrow: If there is a scarcity of available shares to borrow for short selling, it can create a situation where short sellers who want to cover their positions cannot find shares to buy, exacerbating the squeeze.

Real-World Examples of Short Squeezes

Short squeezes have occurred in various financial markets, capturing the attention of investors, traders, and the media. Some notable examples include:

1. GameStop (GME)

In early 2021, shares of GameStop, a struggling video game retailer, experienced an unprecedented short squeeze. A group of retail traders on a Reddit forum called WallStreetBets coordinated buying activity in GameStop’s stock, driving up the price. This led to significant losses for hedge funds that had taken substantial short positions in the stock. GameStop’s stock price surged from around $17 in early January to over $300 at its peak.

2. Volkswagen (VW)

In 2008, Volkswagen experienced one of the most famous short squeezes in history. Porsche, a major shareholder in Volkswagen, revealed that it had increased its stake in the company to over 74%. This surprised the market, as many investors had bet against Volkswagen’s stock through short positions. The sudden surge in demand for Volkswagen shares triggered a short squeeze, causing the stock’s price to skyrocket.

3. Tesla (TSLA)

Tesla, the electric vehicle manufacturer, has seen multiple short squeezes over the years. The company’s stock price has been highly volatile, and short sellers have often targeted it. However, Tesla’s strong performance and positive news announcements have led to short squeezes, with short sellers rushing to cover their positions amid rising prices.

Impact on Financial Markets

Short squeezes can have significant impacts on financial markets:

  1. Volatility: Short squeezes can lead to extreme price volatility, making trading more challenging and unpredictable.
  2. Losses for Short Sellers: Short sellers who are caught in a short squeeze can incur substantial losses, potentially leading to financial distress.
  3. Regulatory Scrutiny: High-profile short squeezes may attract regulatory attention and lead to discussions about market manipulation.
  4. Market Sentiment: Short squeezes can influence market sentiment and trigger speculative trading activity.
  5. Risk Management: Traders and investors need to consider the risk of short squeezes when entering short positions, and risk management becomes crucial.

Strategies During a Short Squeeze

Traders and investors often employ various strategies during a short squeeze:

  1. Avoid Short Positions: Some traders avoid taking short positions in stocks with high short interest to minimize the risk of getting caught in a short squeeze.
  2. Quick Exits: Short sellers may set stop-loss orders to limit their losses and exit their positions if the price moves against them.
  3. Contrarian Trading: Contrarian traders may seek to profit from short squeezes by taking long positions when they anticipate a short squeeze is likely.
  4. Risk Management: Risk management practices, such as diversification and position sizing, become crucial to mitigate the impact of a short squeeze.


A short squeeze is a phenomenon in financial markets where a rising price forces short sellers to cover their positions by buying the security they initially sold short. This buying pressure can lead to a feedback loop of rising prices and significant volatility. Short squeezes have occurred in various assets, from individual stocks like GameStop to entire markets like the Volkswagen case in 2008. Understanding the mechanics and factors contributing to short squeezes is essential for traders and investors to navigate the complexities of financial markets and manage their risk effectively. While short squeezes can create opportunities for profit, they also come with heightened risks and challenges that require careful consideration.

Real-World Examples of Short Squeeze:

  • GameStop Short Squeeze (2021): The GameStop short squeeze in early 2021 is one of the most widely known examples. It was triggered by a group of online retail traders who coordinated their efforts to drive up the stock’s price, causing substantial losses for hedge funds with short positions.
  • Tesla Short Squeezes: Tesla, due to its popularity and stock price volatility, has experienced short squeezes in the past. Positive news or announcements from Tesla’s CEO, Elon Musk, have often led to rapid price increases and short squeezes.

Connected Financial Concepts

Circle of Competence

The circle of competence describes a person’s natural competence in an area that matches their skills and abilities. Beyond this imaginary circle are skills and abilities that a person is naturally less competent at. The concept was popularised by Warren Buffett, who argued that investors should only invest in companies they know and understand. However, the circle of competence applies to any topic and indeed any individual.

What is a Moat

Economic or market moats represent the long-term business defensibility. Or how long a business can retain its competitive advantage in the marketplace over the years. Warren Buffet who popularized the term “moat” referred to it as a share of mind, opposite to market share, as such it is the characteristic that all valuable brands have.

Buffet Indicator

The Buffet Indicator is a measure of the total value of all publicly-traded stocks in a country divided by that country’s GDP. It’s a measure and ratio to evaluate whether a market is undervalued or overvalued. It’s one of Warren Buffet’s favorite measures as a warning that financial markets might be overvalued and riskier.

Venture Capital

Venture capital is a form of investing skewed toward high-risk bets, that are likely to fail. Therefore venture capitalists look for higher returns. Indeed, venture capital is based on the power law, or the law for which a small number of bets will pay off big time for the larger numbers of low-return or investments that will go to zero. That is the whole premise of venture capital.

Foreign Direct Investment

Foreign direct investment occurs when an individual or business purchases an interest of 10% or more in a company that operates in a different country. According to the International Monetary Fund (IMF), this percentage implies that the investor can influence or participate in the management of an enterprise. When the interest is less than 10%, on the other hand, the IMF simply defines it as a security that is part of a stock portfolio. Foreign direct investment (FDI), therefore, involves the purchase of an interest in a company by an entity that is located in another country. 


Micro-investing is the process of investing small amounts of money regularly. The process of micro-investing involves small and sometimes irregular investments where the individual can set up recurring payments or invest a lump sum as cash becomes available.

Meme Investing

Meme stocks are securities that go viral online and attract the attention of the younger generation of retail investors. Meme investing, therefore, is a bottom-up, community-driven approach to investing that positions itself as the antonym to Wall Street investing. Also, meme investing often looks at attractive opportunities with lower liquidity that might be easier to overtake, thus enabling wide speculation, as “meme investors” often look for disproportionate short-term returns.

Retail Investing

Retail investing is the act of non-professional investors buying and selling securities for their own purposes. Retail investing has become popular with the rise of zero commissions digital platforms enabling anyone with small portfolio to trade.

Accredited Investor

Accredited investors are individuals or entities deemed sophisticated enough to purchase securities that are not bound by the laws that protect normal investors. These may encompass venture capital, angel investments, private equity funds, hedge funds, real estate investment funds, and specialty investment funds such as those related to cryptocurrency. Accredited investors, therefore, are individuals or entities permitted to invest in securities that are complex, opaque, loosely regulated, or otherwise unregistered with a financial authority.

Startup Valuation

Startup valuation describes a suite of methods used to value companies with little or no revenue. Therefore, startup valuation is the process of determining what a startup is worth. This value clarifies the company’s capacity to meet customer and investor expectations, achieve stated milestones, and use the new capital to grow.

Profit vs. Cash Flow

Profit is the total income that a company generates from its operations. This includes money from sales, investments, and other income sources. In contrast, cash flow is the money that flows in and out of a company. This distinction is critical to understand as a profitable company might be short of cash and have liquidity crises.


Double-entry accounting is the foundation of modern financial accounting. It’s based on the accounting equation, where assets equal liabilities plus equity. That is the fundamental unit to build financial statements (balance sheet, income statement, and cash flow statement). The basic concept of double-entry is that a single transaction, to be recorded, will hit two accounts.

Balance Sheet

The purpose of the balance sheet is to report how the resources to run the operations of the business were acquired. The Balance Sheet helps to assess the financial risk of a business and the simplest way to describe it is given by the accounting equation (assets = liability + equity).

Income Statement

The income statement, together with the balance sheet and the cash flow statement is among the key financial statements to understand how companies perform at fundamental level. The income statement shows the revenues and costs for a period and whether the company runs at profit or loss (also called P&L statement).

Cash Flow Statement

The cash flow statement is the third main financial statement, together with income statement and the balance sheet. It helps to assess the liquidity of an organization by showing the cash balances coming from operations, investing and financing. The cash flow statement can be prepared with two separate methods: direct or indirect.

Capital Structure

The capital structure shows how an organization financed its operations. Following the balance sheet structure, usually, assets of an organization can be built either by using equity or liability. Equity usually comprises endowment from shareholders and profit reserves. Where instead, liabilities can comprise either current (short-term debt) or non-current (long-term obligations).

Capital Expenditure

Capital expenditure or capital expense represents the money spent toward things that can be classified as fixed asset, with a longer term value. As such they will be recorded under non-current assets, on the balance sheet, and they will be amortized over the years. The reduced value on the balance sheet is expensed through the profit and loss.

Financial Statements

Financial statements help companies assess several aspects of the business, from profitability (income statement) to how assets are sourced (balance sheet), and cash inflows and outflows (cash flow statement). Financial statements are also mandatory to companies for tax purposes. They are also used by managers to assess the performance of the business.

Financial Modeling

Financial modeling involves the analysis of accounting, finance, and business data to predict future financial performance. Financial modeling is often used in valuation, which consists of estimating the value in dollar terms of a company based on several parameters. Some of the most common financial models comprise discounted cash flows, the M&A model, and the CCA model.

Business Valuation

Business valuations involve a formal analysis of the key operational aspects of a business. A business valuation is an analysis used to determine the economic value of a business or company unit. It’s important to note that valuations are one part science and one part art. Analysts use professional judgment to consider the financial performance of a business with respect to local, national, or global economic conditions. They will also consider the total value of assets and liabilities, in addition to patented or proprietary technology.

Financial Ratio



The Weighted Average Cost of Capital can also be defined as the cost of capital. That’s a rate – net of the weight of the equity and debt the company holds – that assesses how much it cost to that firm to get capital in the form of equity, debt or both. 

Financial Option

A financial option is a contract, defined as a derivative drawing its value on a set of underlying variables (perhaps the volatility of the stock underlying the option). It comprises two parties (option writer and option buyer). This contract offers the right of the option holder to purchase the underlying asset at an agreed price.

Profitability Framework

A profitability framework helps you assess the profitability of any company within a few minutes. It starts by looking at two simple variables (revenues and costs) and it drills down from there. This helps us identify in which part of the organization there is a profitability issue and strategize from there.

Triple Bottom Line

The Triple Bottom Line (TBL) is a theory that seeks to gauge the level of corporate social responsibility in business. Instead of a single bottom line associated with profit, the TBL theory argues that there should be two more: people, and the planet. By balancing people, planet, and profit, it’s possible to build a more sustainable business model and a circular firm.

Behavioral Finance

Behavioral finance or economics focuses on understanding how individuals make decisions and how those decisions are affected by psychological factors, such as biases, and how those can affect the collective. Behavioral finance is an expansion of classic finance and economics that assumed that people always rational choices based on optimizing their outcome, void of context.
