Ribbon Communications Inc. (NASDAQ:RBBN) shareholders might understandably be very concerned that the share price has dropped 36% in the last quarter. On the other hand, over the last twelve months the stock has delivered rather impressive returns. During that period, the share price soared a full 101%. So some might not be surprised to see the price retrace some. Investors should be wondering whether the business itself has the fundamental value required to continue to drive gains.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational.

A Different Perspective

We're pleased to report that Ribbon Communications shareholders have received a total shareholder return of 101% over one year. Notably the five-year annualised TSR loss of 4% per year compares very unfavourably with the recent share price performance. We generally put more weight on the long term performance over the short term, but the recent improvement could hint at a (positive) inflection point within the business. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
