Final answer:
Knowing the individual managers and their personal business plans becomes least important when investing as a firm grows and information is more accessible. Other investors will still provide financial capital, and picking stocks is a risky way to attempt to get rich.
Step-by-step explanation:
When deciding how to invest your money, knowing the individual managers and their business plans on a personal basis is least important, especially as a firm becomes at least somewhat established. Once a company's strategy appears likely to lead to profits and information about the company's products, revenues, costs, and profits becomes more widely available, the need for personal knowledge of the management decreases. This is because other investors, such as bondholders and shareholders, do not require a personal connection to provide financial capital to the firm.
It's also worth noting that attempting to pick stocks that will gain significantly in the future is generally regarded as a high-risk strategy and not the most reliable way to build wealth. Instead, investing in a diversified portfolio that balances expected returns with risk is considered a more stable approach for the average investor.
