Market behaves like in the old days

There were once certain truisms about the U.S. equity market that could be relied upon.  One was that during August and during holidays the market would be quiet.  In recent years that has rarely been the case, as anything can happen anytime has been more of the rule.  Now, these three days before Thanksgiving, the market behaved like days of old, before smart phones and trader raiders of various types.  It was quiet.  With the market only open for a half day on Friday, it will likely stay quiet through the weekend.  What a good time to reassess and, for the retail investor who has no impact on the market, make a few changes without fear of whiplash.
