Thoratec (FRA:TL1) Volatility Explanation
Volatility is a statistical measure of the dispersion of returns for a given security or market index. It’s often measured as standard deviation or variance of historical returns over a certain period. The volatility here is measured as the annualized standard deviation between monthly returns from the security over the past year.
Volatility reflects the uncertainty or risk of a security’s value. Generally speaking, a higher volatility suggests a higher risk, because it implies a wider fluctuation around average price. This means the price of the security can change dramatically in either direction within a short period. Conversely, a lower volatility means that the security's price is more steady, which suggests a lower risk.
Another measurement of relative volatility is Beta. Beta is a measure of systematic risk of a security or a portfolio in comparison to the market as a whole. Beta is usually compared to 1. A beta of greater than 1 indicates that the security's price will be more volatile than the market.

Thoratec Corporation incorporated in the State of California in 1976 provides mechanical circulatory support with a product portfolio to treat the full range of clinical needs for advanced heart failure patients. It develops, manufactures and markets proprietary medical devices used for circulatory support. Following the sale of ITC in 2010, the Company has one operating segment: Cardiovascular group. This segment is organized and operates to develop and manufacture mechanical circulatory products to support the cardiovascular systems of humans. The Company's VAD products primarily serve patients suffering from late-stage HF. HF is a chronic disease that occurs when degeneration of the heart muscle reduces the pumping power of the heart, causing the heart to become too weak to pump blood at a level sufficient to meet the body's demands. Hospitals that perform open heart surgery and heart transplants are the potential customers for its Thoratec and HeartMate products. The Company estimates that it sells into 293 of these centers. According to the Company's estimates, it is in approximately 149 centers in the United States and 144 centers internationally. Competition from medical device companies and medical device divisions of healthcare companies, pharmaceutical companies and gene- and cell-based therapies is intense and is expected to increase. It therefore continues to expect new competitors both from the pharmacological and the medical device space. Among the medical device competitors are Aachen Innovative Solutions GmbH, AbioMed, Inc., Berlin Heart GmbH, HeartWare International Inc., Jarvik Heart, Inc., Maquet Cardiovascular, LLC (a division of Getinge AB), MicroMed Technology, Inc., Sun Medical Technology Research Corporation, SynCardia Systems, Inc., and Terumo Heart, Inc. All of the Company's proposed products will require regulatory approval prior to commercialization. In particular, medical devices are subject to rigorous pre-clinical testing as a condition of approval by the FDA and by similar authorities in foreign countries.
