We're Not Very Worried About Mereo BioPharma Group's (NASDAQ:MREO) Cash Burn Rate

Even when a business is losing money, it's possible for shareholders to make money if they buy a good business at the right price. For example, although Amazon.com made losses for many years after listing, if you had bought and held the shares since 1999, you would have made a fortune. But the harsh reality is that very many loss making companies burn through all their cash and go bankrupt.
