What Frank Costanza’s Manssiere Can Teach Us About Investing
Imagine two investors looking at the same market chart. Both are studying price, using historical data, and trying to make informed decisions. From a distance, their approaches may look nearly identical. Up close, however, they may be solving two very different problems:
- The first – let’s call him Kramer – is trying to account for what the market will do based on recognizable past patterns and personal knowledge.
- The second – die-hard fans of the “Seinfeld” TV show already know his name will be Jerry – is focused on what the market is doing now and applying a pre-defined set of rules to decide how to respond.
In investing, this distinction – prediction versus reaction – helps separate discretionary technical analysis from systematic trend following. In “Seinfeld” lore, it’s also what distinguishes a man who chases schemes and hastily launches consumer products like the manssiere from one who stays disciplined to a single profession and adapts based on what is making audiences laugh right now.
The distinction matters because a signal is not the same thing as a process. Seeing something on a chart may suggest an opportunity. A repeatable process goes further by answering questions about what action to take, whether to take a step or a leap, timing, a plan for reducing risk, etc.
