We may have found perfect alpha  But you probably don’t want it in your portfolio

Investment perfection. You’d know it if you saw it, right?

For an investment strategy to fit the bill, most investors would say it needs to consistently beat its benchmark by a healthy margin. The hypothetical fund above has outperformed the traditional 60/40 stocks and bonds portfolio by 200 basis points annually. Even better, it has beaten the 60/40 benchmark every single day since 2000.

We call this mythical unicorn the “perfect alpha” fund. It’s everything most investors want in an investment.

Corsair Took A Hit From Small-Cap Underperformance In Q3; Says Evergrande Not The Next Lehman Brothers

Corsair CapitalCorsair Capital was down by about 3.5% net for the third quarter, bringing its year-to-date return to 13.3% net. Corsair Select lost 9.1% net, bringing its year-to-date performance to 15.3% net. The HFRI – EHI was down 0.5% for the third quarter but is up 11.5% year to date, while the S&P 500 returned 0.6% Read More

But, how much value would this perfect alpha fund have really added to a traditional portfolio?


If you had reallocated 25% of your traditional 60/40 stocks and bonds portfolio to the perfect alpha fund for the last 16 years, you would have increased your annual returns by 50 basis points. However, your volatility and risk would have essentially remained static.



The perfect alpha fund would have added no meaningful diversification to your portfolio.

The downside of outperformance: correlation
This hypothetically perfect investment outperformed its benchmark 100% of the time, and in order to do so, was highly correlated to the market. As a result, it added little value to the risk-adjusted returns of your overall portfolio.

On a standalone basis, the perfect alpha fund delivers what most investors say they seek in an individual investment: consistent outperformance that increases returns. But at the portfolio level, most investors are actually aiming for true diversification: increased returns and lower risk.

The perfect alpha fund is fictional. But, if you’re truly seeking true diversification in your portfolio you wouldn’t want it anyway. I’ts only halfway perfect.

Seeking true diversification
There is a way for investors to potentially increase returns and lower risk—with investments that actually do exist. We call these true diversifiers.

True diversifiers won’t provide most investors with the constant outperformance they want. They won’t outperform the index every day, or even every year. They’re not supposed to.

But true diversifiers can provide the diversification investors need. Their role is to help investors take a different kind of risk, and this can potentially add significant value to your traditional portfolio by adding true diversification—potentially lowering risk and increasing returns in your portfolio over time.
