The phrase “Good investing is boring” typically means that successful investing often involves making wise, long-term investment choices that don't require constant attention or trading. It suggests that a stable and methodical approach, rather than chasing quick gains or constantly reacting to market fluctuations, tends to yield better results over time. Therefore, the correct interpretation is:
C. You’re better off making long-term investments that don’t require day-to-day management.
Es mejor hacer inversiones a largo plazo que no requieran una gestión diaria.
