MIT’s finance lectures on portfolio management break down how professionals build and manage investment portfolios using real data, not theory alone. They cover modern tools like risk-adjusted returns, diversification, and asset allocation, and explain why strategies like 60/40 or risk parity matter. The courses also show how to build portfolios in real markets, not just in a spreadsheet. It’s a hands-on look at how traders and asset managers actually think. Credits: MIT OpenCourseWare, Jake Xia
