I'm creating a SaaS (mostly for myself), that shows a list recommending a few stocks, given a few parameters and analysis. This will be free and updated daily.
I'm thinking about offering other things like reminders (your stock XXXX has reached your desired indicators), newsletters, the option to follow a stock, and to receive the ranked list daily on your e-mail.
How can this be monetized? I'd like to go without ads if possible, and sometimes I think a subscription model is too expensive, even though the information provided is valuable.
