Ah good thought to compare inflows to volume. I guess I am underestimating the amount of trading that is actually going on.  Still seems crazy to me that so much is coming in on net (at least for the ETFs) without significant price appreciation, but obviously I don't know enough about these market dynamics.  

Thanks for your thoughts! 

 Yeah, I find market dynamics overall to be a big mystery myself.  Clearly day traders know something that I don't (or at least they think they do).
