From CNBC.

Five years after the GameStop saga, the most enduring legacy of the so-called "dumb money" era is a structural shift in how markets function. Retail investors did not overthrow Wall Street like they had hoped but they also didn’t vanish completely. Instead, retail became a permanent and influential participant in modern markets. CNBC’s Kate Rooney walks through how small investors have forced platforms, institutional investors and regulators to adapt in ways that continue to shape volatility, risk and investor behavior today.
