How do regulatory and disclosure regimes affect market quality?
Alberta School of Business researcher finds:
- The U.S. over- the- counter (OTC) market contains over 10,000 small and low-priced stocks that are governed by diverse regulatory and disclosure regimes.
- A vast majority of these OTC stocks trade very little, are highly volatile, and perform poorly, making them similar to a lottery ticket for investors.
- OTC stocks in mandatory regulatory and disclosure regimes that are more strict have higher market quality - meaning a greater ease of trading, higher trading volumes and lower risk of stock price crashes.
- Voluntary regulatory initiatives and disclosures by firms also promote market quality.
Studying a comprehensive sample of stocks from the U.S. OTC market, we show that this market is a large and diverse trading environment with a rich set of regulatory and disclosure regimes, comprising venue rules and state laws beyond SEC regulation. We exploit this institutional richness to show that OTC firms subject to stricter regulatory regimes and disclosure requirements have higher market quality (higher liquidity and lower crash risk). Our analysis points to an important trade-off in regulating the OTC market and protecting investors: lowering regulatory requirements reduces the compliance burden for smaller firms, but it also reduces market quality.
