Keryx Biopharmaceuticals is a commercial stage biopharmaceutical company focused on bringing medicines to people with kidney disease. Co.'s marketed product, Auryxia (ferric citrate) tablets, is an orally available, absorbable, iron-based medicine. Auryxia is used for the control of serum phosphorus levels in patients with chronic kidney disease (CKD), on dialysis. Auryxia is also for the treatment of iron deficiency anemia in adults with CKD, not on dialysis. Ferric citrate is also approved in Japan under the trade name Riona and marketed by Co.'s Japanese partner, Japan Tobacco, Inc. and its subsidiary, Torii Pharmaceutical Co., Ltd., and approved in Europe as Fexeric. The KERX stock yearly return is shown above.
The yearly return on the KERX stock yearly return page and across the coverage universe of our site,
is a measure of the annual return over the calendar year 2016 for the given stock.
When performing this calculation it is important to factor in dividends, because a financial instrument's annual return is
more than just the change in price if that instrument pays a dividend or coupon.
One way to factor dividends into the return is simply to count them as cash — we don't do
that here. Instead, our website aims to empower investors
by performing the KERX annual return calculation with any dividends reinvested as applicable (on ex-dates).
