Investment models that account for uncertainty, volatility, and failure succeed in the long term. Events in Ukraine, oil and natural gas markets, commodities, supply chain disruption, and spiking inflation highlight that, while none of these were predictable, all represent increasing uncertainty permeating all markets. The pandemic and war in Ukraine were unforeseen, but that’s just the point, unforeseen events will occur. It is a waste of time to try to predict the specifics, it is an essential investment strategy to manage risk to not only withstand but profit from “certain uncertainty.” Irrationality, not only in human behavior (with unfortunate, often tragic results) but market movements, investment volatility, and bewildering prices, is another certainty. “Mr. Market” as Benjamin Graham said, “is an irrational schizophrenic.” Investing as if he is not assures an investment strategy that will ultimately fail. An increasing number of growth and momentum investment funds are shutting down after sustaining significant losses recently, a sign of the severe pain the selloff in growth stocks is inflicting. More importantly, it signals an inability for investment funds to manage risk and understand that markets and investments do not move in a singular direction for long, and the correction is sudden and painful – regardless of how compelling “momentum” may seem. Risk management is the key to investment sustainability, but this seems to go ignored among most investment professionals. Frequent and extreme volatility is here to stay, and that is likely to decimate growth and momentum funds, as well as highly leveraged equity investment funds (from LTCM in 1998 to Archegos in 2021, the lesson is never learned for long – and there will be more examples to come). Clear and coherent markets, free from political agenda, bad compromises, and ineffective regulation are almost nonexistent. The consequences continue to be pyrotechnic.
