I'm an earlier slack investor, and recently it had a fail breakout above 30 and than a quick flush down below 20 after earnings. Earnings were good, and slack has improved on all fronts but gave some sloppy guidance due to the virus of uncertainty. Overall this flush is a huge buying opp for the stock. I got in on some more options expiring on June 25 strikes and bought some more shares under 20 around 18. Going forward slack will be more used company-wide due to digital takeover and communication in work environments. Zoom is an example of this. Slack is a buy here! , especially under 20 in my opinion.
