VP Chintan Baithak Goa 2019 - Sector: Asset Management & Wealth Management

Which metrics should we use to value wealth management business ? I have seen some fund managers use % of AUM to find market cap.
Also, at what P/E or other metrics can value emerge in this space ?
It’s very much clear that these are high ROE, scalable and growing business, so will get high P/E multiple.
