A lot of others have pointed out the cup and handle formation that slack has made where the handle formed after the last earnings. But also that test of $40 prior to earnings is forming an ABCD pattern that puts the D greater than $50 by end of October. Slack's last earnings report was almost profitable, and their expectations is actually less than their last quarter's performance by 0.01. If slack can pull off a positive earnings, or even 4-5 cents positive they'll prove that they can take on MSFT and potentially emerge a winner in the work productivity space. Since Slack news is few and far between, I find that the recent bearish end of the week trend we had was only due to the way the rest of the market was reacting, since a lot of other big names have been dropping fast. At $29 slack is very near the $27.61 C point which proved to be a point of support. Additionally, $28.77 is a prior point of support from before the point C, which we bounced off of at the end of the day on the 4th (low was $28.00) showing a good sign that it doesn't intend to go lower.
