Alnylam Pharmaceuticals is a commercial-stage biopharmaceutical company developing therapeutics based on RNA interference (RNAi). RNAi is a biological pathway within cells for sequence-specific silencing and regulation of gene expression. Co. has two RNAi-based medicines, ONPATTRO® (patisiran) and GIVLAARI® (givosiran). ONPATTRO is approved by the United States Food and Drug Administration (FDA) for the treatment of the polyneuropathy of hereditary transthyretin-mediated amyloidosis in adults and has also been approved in the European Union, Japan, Canada and Switzerland. GIVLAARI is approved by FDA for the treatment of adults with acute hepatic porphyria. The ALNY stock yearly return is shown above.
The yearly return on the ALNY 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 ALNY annual return calculation with any dividends reinvested as applicable (on ex-dates).
