The Hidden Trade-off: “Risk-adjusted Returns”

You surely have noticed this by now: we disagree with conventional ways of doing many things. Modern Portfolio Theory (MPT) forms the theoretical underpinnings of a lot of investment practice today, without adequate understanding of its deep flaws.

MPT defines volatility as risk. We believe, as Warren Buffett does, that volatility is just volatility – the normal ups and downs – for long term investors. So one common practice is to promote the advantages of getting 80% of the market returns with only 50% of the risk (for example). This supposedly is a superior “risk-adjusted return.”

But you could use the same statistical methodology to show that it may cost you about one third of your potential wealth in 25 years to have a 50% smoother ride on the way. For an investor with $100,000 in long term funds, this might be a $250,000 future shortfall. The question might be, “What fraction of your future wealth would you sacrifice in order to have less volatility on the way?”

The idea of sacrificing future wealth is a lot different than the idea of reducing risk. But they are two sides of the same coin. This is the hidden trade-off in superior risk-adjusted returns.

Our experience is that people can learn to understand and live with volatility. We believe investors get paid to endure volatility.

Of course, our philosophy is not right for everyone. Volatility is easier to tolerate for investors with a longer time horizon. But we believe everyone should see both sides of the coin before making a decision to forego significant potential future wealth for a smoother ride, less volatility, along the way.
