In this special episode, we review the relationship between war and financial markets. War is a tragedy. We are not minimizing the humanitarian tragedy of what is happening in Ukraine by focusing on the potential impact on financial markets. But we are offering a Rational Reminder for investors in a stressful time. Wars and financial markets have coexisted, and often been intertwined, for hundreds of years. Countries that have lost major wars have had their financial markets decimated, while global markets have been relatively resilient, even to major conflicts. In addition to the historical perspective, we offer some timeless lessons for investors to remember in times of stress.
