stuck on this market sizing question
my initial approach is to find 1)estimate how many asset managment firms are in the us 2)how much $ they spend on 3rd party info, and then multiply the two
1st question: i would roughly estimate that perhaps there's about 10,000 firms in the US, but how would i go about making a better estimation on the # of asset management firms
and secondly, how to best segment (perhaps by firm size big, med, small) and average the amount of $ the firms spend? what is a good ballpark for the $ spent on third party info?
