The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But on the bright side, you can make far more than 100% on a really good stock. Long term Ceragon Networks Ltd. (NASDAQ:CRNT) shareholders would be well aware of this, since the stock is up 110% in five years. Also pleasing for shareholders was the 79% gain in the last three months.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...'

A Different Perspective

We're pleased to report that Ceragon Networks shareholders have received a total shareholder return of 73% over one year. Since the one-year TSR is better than the five-year TSR (the latter coming in at 16% per year), it would seem that the stock's performance has improved in recent times. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
