Startups and high-risk companies can prosper in a strong bull market with plenty of liquidity. However, these companies suffer when liquidity is tight or during a bear market. Once listed, these companies must meet certain financial and reporting requirements or face the prospects of a delisting. The Nasdaq has many more delistings than the NYSE.
