Slack's operating loss send easier to recover from. Uber will have to cut costs massively to come closer to profitability. The drop in stock is before the lock in period had expired. Expect it to drop further after October when all the employees dump their stock.

I'd be interested to know how much of those costs are due to driver incentives and other costs related to expansion into new geographic regions vs. costs for established regions.

It could be that cutting costs is as simple as slowing down or pausing the expansion.

But if they don't continue to expand, are they worth their current value? Does their value have the expansion already baked in?
