Half million shares traded - so as basic market principle there were both significant buyers and sellers. We'll soon see who knew what but the behavior is not unusual before conference call after fairly decent run-up.
ZIX does not surprise at these calls so it won't be hard to meet expectations. If expectations are met, can't see much movement either way.
Outlook for ZIX will likely be most important then. Looks like security stocks doing well and are favored at this time so no reason why ZIX will be any different.
