Even if you want to play the overvalued 6 year old plus OvaDx speculation, you buy ARYC and get the same play for a fraction of the valuation you buy it for through OREO. And ARYC is overvalued as it is. You could lose over 80% in OREO to get to a valuation of OvaDX equivalent to buying ARYC - I wouldn't personally touch either one.
