IMO its a function of how illiquid RVXCF is right now...same as RVX but worse today I believe because the Canadian markets were closed.  

I think shareholders are sqeezing their shares tight, which leaves MMs between a rock and a hard place when they get hit with buy orders imo.  Move it up and it could lead to a stampede of buyers giving in to FOMO....take it down and there could be some bottom feeders ready to scoop up cheap non-existent shares.
