The shaded section represents all the possible combinations of time (x) and investment balances (y) for which the stock provides a financial return for the $2,000 investment. This implies that the shaded area is where the guaranteed minimum gain from the bank is greater than or equal to the maximum possible loss from the hedge fund, indicating that investments are likely to yield a financial return rather than a loss.
So, to summarize:
- The shaded section represents all the possible combinations of time (x) and investment balances (y) for which the stock/hedge fund provides a financial return for the $2,000 investment.
