It's good if you're a junior person. It shows that you're willing to work hard and compile information.

The conclusions seem weak to me though; I wouldn't give you my money to invest though if you were interviewing for a portfolio manager type position. If you were and I was a portfolio manager, I'd probably hire you (assuming none of the other interviewees were better) and retrain you if you demonstrated that were up for that.

Traditionally, hedge funds short stocks when they're able to long other stuff as well--if you pulled enough public similar healthcare growth companies and could long those, while proving that $TDOC is the worst of bunch, I'd consider trading on that idea. However, if you're pushing a only short idea, I need something more like a fraud (e.g. Enron) or a likely forever unprofitable business model issue (e.g. Twitter) to even consider short selling (I'm a retail investor so I have almost zero interest in ever short selling as I rationally value my money and therefore rarely am willing to take unlimited downside risk for limited gains). I doubt either exists here--it's just a company that's grown tremendously because the idea behind the business model has potential (lower costs through not-new/not-innovative but very cheap and widely available technology as to increase access to care in hopes it betters outcomes) and there may not be other public competitors or better investment opportunities at this time so that money would want to move there.
