At the risk of turning into r/wallstreetbets here. My bias is to the downside. Driven by a cacophany of pundits on CNBC post-IPO with negative outlooks. "There is absolutely no money to be made in streaming music on the internet" and "apple isn't into music for the profits" and so on ad infinitum. As well as significant short interest in the options market.
$SNAP is probably as nearest neighbor as any for price-action historical context.
Market timing (H1 2019) may also be ill-favored generally for anything tech related if we see significant correction.
But I certainly hope I'm wrong. And will be looking to add positions in Spotify, Dropbox, Uber, Lyft, Docker, Snowflake, AirBnB, SpaceX, WeWork, Stripe etc if and when they become available ;)
