Risk and return are the twin sons of Mr. Market, but the equivalency ends there.
Return doesn’t lend itself to forecasting, at least not in the short term. But when we look further out in time, there’s a bit of transparency at times about what’s coming. Meanwhile, risk’s a bit more reliable generally when it comes to seeing the future, and that small opportunistic opening gives us a leg up on being completely and utterly subject to Mr. Market’s whims.
Shrewdly blending the little intelligence we can gather from the market in terms of risk and return forecasts offers strategic-minded investors the last, best hope for success in portfolio management.
One example: if stocks generally offer a relatively high dividend yield compared with the past, numerous academic studies show that the odds are enhanced for earning higher-than-average returns over the subsequent three to five years and beyond. Mind you, there’s no guarantee, but the higher the yield, the better the odds. But we can’t rely on this prospect alone, which is why we can’t apply this concept to one or two stocks. Instead, we greatly improve our odds of tapping higher-than-average returns by diversifying.
In other words, buying a broad portfolio of stocks at a relatively high dividend yield further increases our chances for beating the buy-and-hold long run performance. Combining the two risk management strategies–buying when yields are high and diversifying the bet–offers more confidence of earning above-average returns than either strategy does in isolation of the other.
We can further enhance our prospective risk-adjusted return by taking the advice above and applying it to multiple asset classes. Once again, we must do so intelligently, by leveraging what we know about risk and it’s slightly better odds (compared to pure return forecasts) for extrapolating the past into the future. That is, correlations and volatility matter when considering how to intelligently blend multiple asset classes for above-average results.
If we look to bonds, we know a lot in terms of how they compare to stocks. We don’t what the returns of each are going to be, at least not completely, but their relationship tends to be fairly stable over time. One, bonds tend exhibit relatively low standard deviations and correlations compared with equities. Again, that information by itself isn’t much help, but it becomes quite useful when combined with what we know about stocks, as per our review above.
