My wife and I are retired and have been living comfortably on our investments for some years. I spend part of my time managing those investments. My investment approach is based on my macro views and I trade infrequently to adjust our portfolio to changes in asset prices and my perception of the macro environment. My background is in science and engineering rather than in finance or money management, but the analytic skills and skeptical viewpoint that served well in my career have proved to be very helpful in my investment decision making. Frequently, the common wisdom regarding the macro environment is both unwise and disturbingly common. This provides a potential advantage to those willing to think independently. But at the same time, when one bets against the prevailing view, caution is of utmost importance, since the market may fail to recognize the truth for an unpredictably long time. Thus, a barbell investment approach has been found to be essential, with enough hedge assets to ride out the recognition delay.
