Edit: "<...individual stocks...> are there other ways not typically discussed in the mainstream?" You haven't mentioned not timing the market, and instead investing in low-load index funds.

There's another company that's partners with Morningstar offering a direct API to protect portfolios here https://vectorspacebio.science/finance
Hope that helps!
We’re a roboadvisor that acts like a quantitative hedge fund, and so we share all that cool data with you from data-backed strategies on decades of market data, to showing your portfolio sharpe ratio, automated recommendations based on market evolution (the API for sector-risk alerts you were talking about), and more.
