Instead of opting for the median, going for both of the extreme ends of some situation in an attempt to remove downside.
In investing, it translates to investing in short- and long-term bonds, and not opting for the intermediate duration bonds.1
Never go for the median. Always go with two extremes to remove downside.
For example with weight lifting: Heavy lifts and long effortless walks instead of going hard sometimes and walking at a decent pace with incline.
Also called “bimodal strategy”.
