One odd thing in 2019 has been Slack’s falling share price contrasted against the rising value of the Nasdaq composite, a tech-heavy index that many use as shorthand for the US tech market. Why one of tech’s hottest, and fastest-growing companies was losing altitude while tech stocks themselves broadly rose has been interesting to unpack.

Whether it was software-as-a-service’s (SaaS) modest repricing from summer highs, Microsoft’s Teams push, or Slack’s initial value just being too high, what the workplace productivity company is really worth has been an open question since it began to trade earlier this year; what became plain as the year went along, however, was that its initial trading range (above $40) and direct listing reference price ($26) were far too high, and a little too high, respectively.
