Edward Quince's Wisdom Bites: The Marks Series - The Futility of Macro Forecasting and the Value of "I Don't Know"

Edward Quince (EQ): Howard, one of the prevailing themes on this blog is the inherent uncertainty in financial markets, often summarized by the difficult answer, "I don't know". You've written extensively about the value—or lack thereof—in forecasting the future. Why is macro forecasting an area you advise investors to largely ignore?

Howard Marks (HM): Macro predictions are unlikely to give you an edge. There are two main problems. First, we don’t know what’s going to happen. The world is too complex, too erratic, and too full of surprises to make spot forecasts of anything of significance. Second, even if a forecast turns out to be correct, we don't know how the markets will react to what actually does happen. Forecasting is uncertain, so it's safer not to try to time markets based on predictions.

EQ: You mention that in efficient markets, correct forecasts are potentially very profitable, but also hard to make consistently. Is the consensus view of economists any better?

HM: The consensus view is usually an extrapolation of the current condition and is already embedded in the price of an asset. Most forecasts tend to cluster around historic norms and call for only small changes, underestimating the potential for radical change. If you are merely forecasting the most likely outcome, you are highly unlikely to hang your spreadsheet on predicting a discontinuity. Furthermore, most forecasters have average ability, and we rarely see their track records.

EQ: You advocate for the "I don't know" school of investing. What does this intellectual humility require of an investor in terms of action?

HM: The "I don't know" investor must face up to the uncertainty that surrounds the macro future. Instead of trying to divine the next economic move, we should devote ourselves to specialized research in market niches that others find uninteresting or overly complicated. We will continue to try to "know the knowable". This means focusing on micro factors relating to companies, assets, and securities where it is possible to obtain a knowledge advantage through the expenditure of time and effort. By concentrating on avoiding pitfalls and investing based on in-depth analysis, conservatively estimated tangible values, and modest purchase prices, we can proceed without relying on macro-forecasts.

EQ: So, the valuable forecasts are those that call for radical change, but those are rarely right. In lieu of perfect foresight, how do we protect ourselves?

HM: We must acknowledge the limits of our knowledge. This humility should drive us to employ the Margin of Safety. The margin of safety is, in essence, rendering unnecessary an accurate forecast of the future.

The Edward Quince Takeaway

Embrace intellectual humility: recognize that "Nobody knows" the macro future, and those who claim certainty should be met with skepticism. Focus your efforts on knowing the knowable—deep, bottom-up research in niche areas where superior insight is achievable—and rely on a robust Margin of Safety rather than unreliable predictions.
