“If you live in New York City, for example, chances are you will not be going outside for a leisurely stroll down Fifth Avenue in shorts and a T-shirt and flip-flops in the month of February. Why is that? Because, if you’ve lived there for a while and experienced the local seasons, you’ve already identified that in February it will be pretty darn cold. To appropriately adapt, you will want to wear a heavy winter coat and maybe gloves and a scarf and earmuffs. It’s the same with the markets. You need to have “lived there for a while” and experienced a variety of market cycles so you know what “to wear,” or rather how to adapt, so that you are financially comfortable. Instead of knowing to wear a winter coat in February, you will know that in a choppy, sideways, bracketed market you need to adapt your system and rules so that you do not get whipsawed and stopped out a lot. Or you may need to recognize a bull market changing to a bear market so that you can exit your position in a timely fashion to lock in profits.”
