Overreaction refers to the phenomenon where investors react too strongly to new information, causing prices to move excessively in one direction. This can lead to market inefficiencies and opportunities for investors who can identify and capitalize on these overreactions.

Value investing is an investment strategy that involves buying stocks that are trading at a discount to their intrinsic value. The value premium anomaly suggests that these stocks tend to outperform stocks with high price-to-book ratios over the long term.

Herding refers to the behavior of investors who follow the actions of others, often without conducting their own independent research. This can lead to market bubbles and crashes, as investors pile into popular stocks and drive up prices to unsustainable levels.

Momentum investing is an investment strategy that involves buying stocks that have been performing well recently, with the expectation that they will continue to perform well in the near future. The momentum anomaly suggests that these stocks tend to outperform stocks with low momentum over short periods.

A selling climax occurs when investors panic and sell stocks indiscriminately, often driving prices down to extreme lows. This can be caused by negative news or events, but it can also be triggered by technical factors, such as a break below a key support level.

Dividend investing is an investment strategy that involves buying stocks that pay regular dividends. The dividend yield anomaly suggests that these stocks tend to outperform stocks with low dividend yields over the long term.

Familiarity bias refers to the tendency of investors to favor stocks that they are familiar with, even if they are not necessarily the best investments. This can lead to investors overpaying for stocks that are popular and well-known, while overlooking undervalued stocks that are less familiar.

Mean reversion is the tendency of prices or returns to move back towards their long-term average. The mean reversion anomaly suggests that stocks that have recently performed poorly are more likely to rebound and outperform stocks that have performed well.

Analyst recommendations refer to the practice of financial analysts providing buy, sell, or hold recommendations on stocks. Investors often follow these recommendations, even if they have not conducted their own independent research. This can lead to market inefficiencies and opportunities for investors who can identify and capitalize on overvalued or undervalued stocks.

Institutional ownership refers to the percentage of a company's shares that are held by institutional investors, such as pension funds, mutual funds, and hedge funds. The institutional ownership anomaly suggests that stocks with high institutional ownership tend to outperform stocks with low institutional ownership.

Earnings surprise refers to the difference between a company's actual earnings and the earnings that analysts had forecast. Investors often react positively to positive earnings surprises, which can lead to short-term price increases. This is known as the earnings surprise anomaly.

Short interest refers to the number of shares of a stock that have been sold short. The short interest anomaly suggests that stocks with high short interest tend to underperform stocks with low short interest. This is because short sellers are betting that the stock price will decline, and they are forced to buy back the stock if the price rises.

Index inclusion refers to the practice of adding a stock to a popular stock index, such as the S&P 500 or the Nasdaq 100. This can lead to increased demand for the stock, as investors who track the index are forced to buy it. This is known as the index inclusion anomaly.

The index inclusion anomaly suggests that stocks that have recently been added to a popular stock index tend to outperform stocks that have not been added. This is because investors who track the index are forced to buy the newly added stocks, which can lead to increased demand and higher prices.

Word-of-mouth refers to the practice of investors sharing stock recommendations with friends, family, or colleagues. This can lead to increased demand for the stock, as investors who receive the recommendation may buy it without conducting their own independent research. This is known as the word-of-mouth anomaly.
