As a general rule the last few months, good companies are getting punished for "just" meeting earnings/revenues. Any hint of bad guidance crushes. Like politicians, executives are being rewarded for lying about the past and providing false hope about the future. Based on past WFM earnings results, it will either be up or down 6-10% by market close tomorrow. It will not stay flat. Based on abyssmal prognosticating on my part over the last several months, probably going up (I'm heavily short via Feb strike puts).
Doesn't mean it's worth it however. In the real world, right now, this is an $80'ish stock. However, as I said earlier, we're now evidently residing in utopia.
