Make more money.  Some investors look to optimize for highest returns above all over time.  These are typically ultra high net worth individuals or sovereign wealth funds that can tolerate volatility for long periods of time.  Such investors might invest in the most nascent of asset classes, e.g., internet domain names, lifetime individual income, litigation finance, virtual currencies, cryptocurrencies, receivables, patents, frequent flyer miles, timber, farms/ranches, art, collectibles, or carbon or carbon  credits.  Fund managers that optimize for high returns over other Jobs include activist investors such Bill Ackman at Pershing Square and Bruce Berkowitz at Fairholme Funds.  At a Boys & Girls Harbor Investment Conference, Bill Ackman and Ray Dalio debated the merits of each other’s strategies; Dalio warned that Ackman’s investment strategy poses “risk of ruin”.  Warren Buffett’s value-focused Berkshire Hathaway also optimizes for returns, and may accept as a result short term underperformance.
