Stock buybacks are when a company purchases some of its own shares of stock

A short squeeze happens when short sellers increase stock prices by buying shares back quickly

When short sellers realize their positions may be incorrect—usually triggered by increasing share prices—they often try to quickly buy back their shares in order to minimize their total losses. When this happens on a large scale, that buying activity can drastically increase to represent the seemingly high demand for that stock. The result is called a "short squeeze," which refers to short sellers literally being squeezed out of their positions by rising prices.

What are repurchasing agreements?

Repurchasing agreements are short-term trade agreements in which a dealer sells securities and agrees to repurchase them at a higher price soon after (often within 1 to 2 days). This gives dealers quick access to cash and allows the purchasing party, often the Federal Reserve, to control liquidity in securities. This can be used to alter the money supply, which is a key element in combating deflation.

Shares are parts of a stock that represent ownership of a company

Bear raiding is a manipulative tactic to bring a stock price down—and part of why short selling can be controversial

Bear raids occur when short sellers use manipulative tactics—like spreading false rumors or coordinating trades—to artificially drive down a stock's price and profit from short positions. Although bear raids are an illegal form of market manipulation, they can spook investors, prompting large selloffs of shares and causing a company's value to plummet. As a result, investors may be hesitant to invest in the company in the future, creating a feedback loop of stock downturn.

Read about why bans on short selling are a controversial policy

Generally, short selling is legal, but regulations often restrict short positions when a stock has experienced a sharp price decline (more than 10% in one day). However, negative feedback loops in times of financial crisis have given short selling a bad reputation. The government has temporarily banned short selling during previous market downturns—like The Great Recession of 2008 and the early months of the COVID-19 pandemic—but experts argue whether those bans actually improved market stability or just distorted prices.

Activist investors use large ownership positions to influence companies

By holding large ownership positions, which often come with leveraged access to a company's board or the ability to force a shareholder vote, activist shareholders can change a company's corporate governance, leadership, and overall direction.

Carbon markets incentivize companies to cut emissions but require high carbon prices

To reduce greenhouse gas emissions, a cap-and-trade system issues a limited number of emissions permits—carbon credits—that decrease each year, cutting into a company's profits if it does not reduce emissions and must buy permits from others. However, cheap permits and minimal fines for lacking permits have reduced the system's effectiveness.
