Nice stuff. Based on the volume chart, that's a VERY disciplined and paced set of buys (by Z standards compared to their charts over the past 5 weeks), and it all zeros right in on $32.50.
It's too rich for anyone internal (at least $5m re-invested), so I'll wager it's an initial programmed short covering ahead of Jan 18th expirations.
Is so (one Short feasting on another Short), the remaining question is: Will the other shorts pounce and push the recent movements back under $27 out of spite, or will they do nothing and wait and see, or will some of them begin their covers early too?
My gut says this pulls back to $30, and we get a new channel of $29 to $33 for the rest of the month -- UNLESS Zillow puts out some actionable news.
101% my worthless opinion only, and good luck to all,
