What are designated market makers responsible for?

Designated market makers play a crucial role in ensuring the liquidity of the stock market. Their primary responsibility is to facilitate trading by consistently buying and selling securities. This activity helps to maintain an orderly market, enabling other investors to execute trades more easily. Since they are obligated to provide liquidity, market makers can help stabilize prices and reduce volatility by ensuring there are willing buyers and sellers for a given security at all times.

The function of market makers is essential in a stock exchange environment, as they bridge the gap between buyers and sellers. When demand for a stock surges or plummets, designated market makers can step in to buy or sell shares, thereby helping to mitigate any potential disruptions in trading. This ability to manage orders and supply is what distinguishes them from other participants in the market, making their role indispensable for maintaining market efficiency.

In contrast, the other options refer to roles that do not align with the specific functions of market makers. Regulating interest rates falls under the purview of central banking authorities, the creation of new financial regulations is typically handled by government agencies or regulatory bodies, and developing investment strategies for individual investors is a task more suited for financial advisors rather than market makers.
