One side effect, though, is that both companies left a lot of cash on the table on Thursday.

Airbnb shares more than doubled when it opened, giving it a market value of more than $100 billion.

On Wednesday, food delivery service Door Dash saw its stock pop about 80% higher, thin the share price it had settled on prior to the Open.

It's now worth about $55 billion.

The volume of shares trading for both is probably a fraction of what was sold, which could be the reason for the run up in the price.

Tight supply will drive up demand, but Door Dash could have raised at least a billion dollars more without getting egg on its face.

The same holds for Airbnb.

Getting a lot of cash is important.

Door Dash saw a huge spike in customers and revenue tripled for the first three quarters in the year.

Compared to last, more people are eating in because of the pandemic.

But that will soon change and Doordash has fierce competition with Grubhub and uber Airbnb was hurt because of global lockdowns, but it's on the upswing as people will start to travel again.

But the company had to take on debt and needs to invest in ways to properly that hosts and travelers.

Having extra money around is never a problem, and it could at least go to cover some costs and expenses.

It never hurts to prep for bad times when things were good.
