Hello, Sometimes there are companies that are growing revenues, but still operating at a loss. It can be a new company, or an old company doing a turnaround. How do you evaluate investing in such a company? I find it a difficult concept to invest in a company that is operating at a loss. But people do it all the time. Some companies like Tesla have never posted a profit and have been around for years. But the investment community still pays a huge price for the stock.
