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.

Retail investors are getting burned by long/short strategies

Tesla short sellers benefited from the company's poor performance in 2025

Tesla was widely considered the most-shorted stock until 2024, despite consistent short-seller losses.

Supporters of payday loans say banning them would harm low-income Americans

Many argue for a federal policy that would cap interest rates for these loans, but payday lenders say that would make it impossible for them to make money, effectively forcing them to close up shop.

Stock options give investors the right to buy or sell a stock at an agreed-upon price and date

There are two types of options: calls, which are bets that a stock will rise (or not rise past a certain point), and puts, bets that a stock will fall (or not fall past a specific level). While stock options give investors the right to do these trades, they do not obligate buyers to follow through with them—sellers, on the other hand, must perform the option if it is exercised
