When creating a stock portfolio, individuals can purchase stocks through platforms such as stock exchanges, online brokerage firms, or financial advisors. The reason to consider diversifying a portfolio, which means investing in a variety of assets, is to mitigate risk. No single investment's performance can disproportionately harm the overall performance of a diversified portfolio as losses in one area can be offset by gains in another.
To raise funds for a firm's expansion, choosing between borrowing (taking on debt) and issuing stock (equity financing) should be based on factors like the company's debt level, ownership dilution preferences, and future revenue projections. While borrowing does not dilute ownership, it requires regular interest payments. Issuing stock does not require repayments but does dilute ownership and may influence company control.
