| Exagen is engaged in commercializing a portfolio of testing products under its AVISE® brand, several of which are based on its Cell-Bound Complement Activation Products (CB-CAPs) technology. CB-CAPs assess the activation of the complement system, a biological pathway that is implicated across various autoimmune and autoimmune-related diseases, including systemic lupus erythematosus (SLE). Co.'s main testing product, AVISE® CTD, enables diagnosis for patients presenting with symptoms indicative of a variety of connective tissue diseases (CTDs), and other related diseases with overlapping symptoms. AVISE® CTD utilizes Co.'s CB-CAPs technology to enable the diagnosis SLE. The XGN YTD return is shown above.
The YTD Return on the XGN YTD return page and across the coverage universe of our site,
is a measure of the total return for a given investment year-to-date for the current calendar year
(up to the end of prior trading session). Arguably, choosing the current calendar year for a measurement
period is on the one hand completely arbitrary, but on the other hand a year-to-date look can be extremely
useful in the context of our country's tax system which taxes gains and income on a calendar year basis.
Thus, researching Year-To-Date Returns is good practice for investors — whether XGN YTD return or other benchmarks/peers
— and when doing so it is also important to factor in dividends, because a financial instrument's YTD 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 XGN YTD return calculation (with any dividends reinvested as applicable), and to provide a
coverage universe of many stocks and ETFs to be able to compare YTD returns.
