I also just modified the table schema to not allow NULL values on any of the indexed columns.. No faster..
What i dont understand is that each query individually only returns 6000 rows and its a matter of combining them then using the join condition..
I also meant to say, i know that the correct schema format would be to have the stocksymbol use foreign key instead of duplicating the char column and joining on integers then instead of char columns but this was a design i cant change because of legacy reasons (crap i know).
