key idea behind alternative beta stacking: find alternative betas to stack that:
- have historically deliveredp positive excess returns
- low correlation with sp500
- lowly correlated each other
2 examples of strategies that have these characteristics (historically):
-
managed future trend following: taking long and short positions in commodities, currencies, IR and equities using quantitative and systematic methods to find trends
-
guture yield (carry) strategy => return accrues to the investor is there's no chane in price (coupon and dividens are such an example). currency and commodity can do the same.
- with fx. we can buy a currrency with low IR and puschase short-term bills demonitated in a currency with higher rates
- commodity carry: long position where the roll yield is positive (backwardation) and short where the roll yield is negative (contango)
