Slack ends first day of trading where it started

Data: Factset; Chart: Axios Visuals

Slack closed its first day of trading on the public market at $38.62 a share, 0.3% up from its opening price of $38.50.

The bottom line: It didn't close notably higher than its opening price, but a steady first day is a good result for Slack's unorthodox choice of a direct listing.
