“When all you have is a hammer, all the world looks like a nail.” I first heard that saying in medicine (referencing how each specialist cares solely about his or her organ system of interest). I always liked it. The saying applies in finance too. Being focused on the markets, it sometimes seems that the world has changed after a day of big moves in the market (or even more so after a week of such moves).
However, after such moves, I’ll sometimes speak to friends (outside of finance) and ask if they noticed the markets of late. Most often they reply something like “No, what have they been doing.”
Markets can influence sentiment, and they may have predictive value at times. But stocks markets are not the actual/real world. Stock prices have changed; the world most likely has not.
