The Impact of Social Media Influencers and 'FinTok' on Retail Investor Behavior and Market Volatility

Abstract

This study examines the growing influence of social media platforms and financial influencers, or "finfluencers," on the behaviors of retail investors and broader market volatility. The rise of platforms like TikTok, leading to the emergence of the "FinTok" subculture, has democratized access to financial information but also introduced new risks. Finfluencers, often lacking professional credentials, leverage their large followings and parasocial relationships to dispense investment advice and promote specific stocks, cryptocurrencies, and other financial products. This research investigates the mechanisms through which this influence operates.

The analysis finds that finfluencer recommendations can lead to coordinated herding behavior among retail investors, driving rapid and often short-lived price increases in promoted assets. This phenomenon, fueled by the Fear of Missing Out (FOMO), can create significant though temporary market volatility, particularly in small-cap stocks and speculative assets. Furthermore, the findings suggest that reliance on finfluencers is inversely related to an investor's financial literacy, with less informed individuals being more susceptible to speculative advice and potential market manipulation.

The paper concludes that while social media has the potential to increase financial engagement and literacy, the unchecked influence of finfluencers poses systemic risks. The speed at which information (and misinformation) spreads can create asset bubbles and sudden market downturns, challenging traditional market stability mechanisms. The study highlights the urgent need for a regulatory framework to address the ethical and legal implications of finfluencer activities, ensuring greater transparency and investor protection in an increasingly digital financial landscape.
