How Common Is Stock Price Manipulation?

Estimating the true frequency of stock price manipulation is a difficult task. By its very nature, manipulation is a clandestine activity, designed to evade detection. However, a groundbreaking study has shed some light on this shadowy area, suggesting that manipulation may be more widespread than previously thought. The research indicates that approximately one percent of all closing prices are subject to manipulation.
- Information Asymmetry: Stocks with high levels of information asymmetry, where some investors have access to privileged insights, are more susceptible.
- Liquidity Levels: Stocks with mid to low levels of liquidity, meaning they aren't traded as frequently, are also at higher risk.
- Month-End and Quarter-End: Manipulation is more likely to occur on these days, often driven by fund managers seeking to boost their reported performance.
Staying Vigilant in the Market
While the findings on market manipulation might sound unsettling, remember that regulators and market participants are continuously working to improve detection and prevention measures. By staying informed, diversifying your investments, and understanding the risks involved, you can navigate the stock market with greater confidence and protect your financial future. The goal is not to scare you away from investing, but to empower you with the knowledge to make sound decisions and be aware of potential pitfalls.
