Max pain is the price where the total value of all open calls and puts would be lowest at expiration, so option buyers as a group would lose the most. Some traders watch it as a level the stock may drift toward near expiration, because option sellers, often market makers, hedge their positions in ways that can pull the price toward heavily traded strikes. It is a theory, not a guarantee.
