Asymmetric is an imbalance, or unequal. Asymmetric returns. for example, is an asymmetric risk/reward profile: one that is imbalanced or skewed toward the upside than the downside. Investors prefer to capture more of the upside, less of the downside.
Alpha is the excess return of the fund relative to the return of the benchmark index or an abnormal rate of return. The term alpha was derived by the academic theory “Capital Asset Pricing Model (CAPM).
The two terms, asymmetric and alpha, are very different and probably should not be used together. The first is about absolute returns. The later is about relative returns. So, I believe we have to pick one of the other, rather than use them together.
