When directors are considering the type of funding to pursue for their expansion plans, the most relevant factor to keep in mind from the provided options is changes in the stock market.
This is because fluctuations in the stock market can impact a company’s ability to raise funds through equity financing (i.e., issuing new shares) or affect the terms of debt financing. It's important for the directors to assess the current market conditions and investor sentiment to determine the most advantageous approach for securing the necessary capital. Other factors like interest rates from banks, the costs of borrowing, and bank savings account types are less directly relevant to the immediate need for expansion funding.
