As every investor would know, not every swing hits the sweet spot. But you have a problem if you face massive losses more than once in a while. So spare a thought for the long term shareholders of Mobico Group Plc (LON:MCG); the share price is down a whopping 88% in the last three years. That'd be enough to cause even the strongest minds some disquiet. And more recent buyers are having a tough time too, with a drop of 45% in the last year. The falls have accelerated recently, with the share price down 58% in the last three months. We note that the company has reported results fairly recently; and the market is hardly delighted.

Mobico Group isn't currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. Shareholders of unprofitable companies usually desire strong revenue growth. Some companies are willing to postpone profitability to grow revenue faster, but in that case one would hope for good top-line growth to make up for the lack of earnings.

In the last three years, Mobico Group saw its revenue grow by 13% per year, compound. That's a fairly respectable growth rate. So it's hard to believe the share price decline of 23% per year is due to the revenue. More likely, the market was spooked by the cost of that revenue. This is exactly why investors need to diversify - even when a loss making company grows revenue, it can fail to deliver for shareholders.
