Ocean conditions can be calm one day only to be rough the next. This volatility is an important aspect of surfing because different ocean conditions call for different surfboards. Avid surfers know they are required to own a diverse collection of surfboards, allowing them to ride a variety of waves. From an investor’s perspective, market conditions are also constantly changing and, as in surfing, no single investment vehicle works well in every market condition. Thus, diversification is as imperative when investing as it is when surfing.
