Sources I found helpful for your financial research journey

1. Damodaran Online: has been online since 1998. Aswath Damodaran is a Professor of Finance at the Stern School of Business at New York University. You can find here models for most of conventional valuation models, such as Dividend Discount model, Free Cash Flow model, Option Pricing model, Private Firm Valuation model, etc. Once you generate necessary inputs, the models will yield sufficient outputs.

2. Reuters Finance: I believe this is one of the most useful free website about market data of finance. Reuters Finance generates update and detailed data and news of listed companies, their analysis, etc. Once you do financial analysis on your own, this is impartial source to refer.

3. Bloomberg Industries: Once you conduct the industry analysis, you will figure the free data of this section is poorly few. Perhaps because it is more difficult to generate data of the whole industry, these packages of data are normally for sale. Fortunately, Bloomberg Industries offer us a free source of such data. Most of industries with market leaders are pointed out with equivalent market weight.
