I micro-invest in companies I am familiar in working with at my job. Mostly bio-tech/healtcare/pharm. I have a 403B that is invested in index funds and bonds that is more serious savings. The Robinhood account is more like… a shoe closet. I buy the shoes I like and rarely sell them unless they, well give me a bad experience in real life (looking at your Reddit, Amazon, and Meta). After Trump was elected… I expanded my horizons to European ETFs and Chinese car companies.
