Behavioral Finance and Disposition Effect

Investors are more likely to sell stocks that have gained value (winners) compared to stocks that have lost value (losers).

Investors tend to sell mutual funds that have performed poorly more often than those that have performed well.

The reverse disposition effect is stronger when investors believe they have less control over a fund's performance, such as in passively managed funds.

Making investors justify their initial investment decisions can amplify both the disposition effect in stocks and the reverse disposition effect in funds.

Highlighting the role of fund managers can also strengthen the reverse disposition effect.

The price of a security deviates from its intrinsic value, often due to irrational investor behavior.

Investors who base their decisions on short-term trends or speculation rather than fundamental analysis.

The concept that market imperfections like high trading costs and short-selling constraints prevent prices from rapidly adjusting to their fundamental values.

The theory that irrational investors drive prices further away from fundamentals by buying assets based on the expectation that 'someone else will pay more later'.

The study of how past economic experiences, especially market returns, influence individuals' risk tolerance and investment decisions.

People who have experienced low stock market returns tend to be more risk-averse, invest less in stocks, and allocate less of their liquid assets to equity investments.

Past market experiences, even those from long ago, can influence investment decisions, with recent experiences having a more significant impact.

The extent to which a company's market value exceeds its book value.

Periods of heightened merger activity, often driven by market misvaluation or specific industry trends.

A theoretical framework suggesting that firms with high M/B ratios, indicating overvaluation, are more likely to engage in mergers.

A theory suggesting that merger waves are driven by correlated valuation errors and misperceptions of synergies, particularly when acquirers are overvalued.

A behavioral theory suggesting that overvalued acquirers use their inflated stock prices to acquire less overvalued targets, benefiting short-term managers.

Overvalued firms, often driven by market or sector misvaluation, tend to acquire less overvalued firms.

Stock-based transactions become more prevalent during overvaluation waves, with cash targets being undervalued and stock targets being overvalued.

When acquirers are significantly overvalued, stock transactions are favored as target managers may misinterpret the high stock price as evidence of synergies.

The findings suggest that behavioral biases and learning impact asset pricing and market behavior, challenging traditional static models of risk preferences.

Institutional investors were the primary drivers of the price increase in technology stocks during the Dot-Com bubble (1997-2000), while individuals were the main buyers after the bubble burst.

Institutions, particularly hedge funds, independent advisors, and mutual funds, made significant discretionary purchases of high-priced technology stocks, often exceeding their intrinsic value.

Institutional investors began selling their technology stocks in a coordinated manner around the peak of the bubble in March 2000.

Individuals, particularly those using discount brokerage services, bought technology stocks as prices were collapsing, demonstrating poor timing.

After the bubble burst, individuals continued to buy technology stocks while institutions shifted their investments to non-tech sectors, indicating a difference in market sophistication.

Institutional buying led to larger post-peak reversals in returns, especially for the largest companies, suggesting that they played a role in mispricing.

Institutional investors exhibited speculative behavior by trading based on factors other than fundamental values, leading to price deviations.

Institutions bought technology stocks aggressively, driving prices away from fundamental values, which led to larger price corrections after the bubble burst.

The study uses data on NASDAQ technology firms to examine whether institutional investors contributed to mispricing or traded based on fundamentals.

The study's findings align with the Abreu and Brunnermeier (2003) model, which explains how rational arbitrageurs participate in bubbles until a coordinated selling effort occurs.

Institutional investors actively participated in the housing bubble by buying overpriced assets, fueling the bubble further, then selling off their investments, triggering the market crash.

Individuals invested in depreciating assets during the crash despite the declining market, sustaining the demand for these assets.

The widespread belief that markets operate efficiently, meaning prices reflect all available information, is challenged by the study's findings.

The study aims to determine if securitization agents were aware of the housing bubble and the impending market crash during 2004–2006.

Securitization agents, instead of showing cautious behavior, increased their housing exposure by purchasing second homes and upgrading to more expensive ones.

The behavior of securitization agents, contrary to expectations, suggests over-optimism and a distorted belief in the housing market's performance.

Securitization agents were more likely to divest homes during the bubble period, indicating a potential awareness of the market's vulnerability

Securitization agents were less likely to acquire additional housing exposure, suggesting caution and anticipation of a potential market downturn

The overall housing portfolio performance of securitization agents was expected to be better due to their perceived expert market knowledge

Securitization agents were expected to make purchases more conservatively relative to their income, implying a cautious approach to spending
