The Average Annual Return on the ALXN average annual return 10 years page and across the coverage universe of our site,
is a measure of the annualized return over the past ten years (or specified start date) for a given investment
(up to the end of prior trading session recorded). Arguably, choosing ten years for a measurement
period is on the one hand completely arbitrary, but on the other hand provides a sufficiently long window
to capture long-term trends.
Thus, researching Average Annual Returns is good practice for investors — whether ALXN average annual return 10 years or other benchmarks/peers
— and when doing so it is also important to factor in dividends, because a financial instrument's annualized return is
more than just the change in price if that instrument pays a dividend or coupon. Our website aims to empower investors
by performing the ALXN average annual return calculation with any dividends reinvested as applicable (on ex-dates).
