I'm trying to understand universe selection in QC.  I have a Quantopian algo that generates a lot more trades than the version I have recreated in QC.  To get to the source of the difference, I've created the attached basic algo that simply prints a list of the current active universe.  When I specify a handful of stocks in the universe, not all of them are included.  AAPL and MSFT gets printed.  INO does not.

Could anyone please help me understand why?
