Understanding CRSP indexes

from key concepts described at crsp.com

CRSP(Center for Research in Security Prices) provides indexes for the investment community and academic research groups. After I studied the key concepts of CRSP indexes from their web site http://www.crsp.com/indexes-pages/crsp-indexes-our-key-concepts, I made a simple presentation about concepts on prezi.com which is a great online presentation tool.
