In addition to all the common-sense advice (get diverse [probably index] funds, balance them appropriate to your situation, avoid high fees etc), here are some tools I use: - etfdb, an outstanding repository of information about individual exchange-traded funds. https://etfdb.com/ https://etfdb.com/ - morningstar x-ray, a platform for evaluating the balance of an entire portfolio. Good for seeing where your exposure is given different hypotheticals. https://www.tdameritrade.com/education/tools-and-calculators/morningstar-instant-xray.html https://www.tdameritrade.com/education/tools-and-calculators... - fossilfreefunds.org, an engine for evaluating the carbon exposure for funds. There's a staggering amount of oil/gas/coal currently on the books as value for companies that ultimately will need to stay in the ground. You and me likely aren't running in the circles capable of picking the winners in this carbon bubble, so I generally try to avoid my exposure (I don't want to left holding that bag). https://fossilfreefunds.org/ https://fossilfreefunds.org/
