SCHA offers, with a massive list of 1,800 stocks – many of which you won’t recognize because it excludes the big corporations that dominate other index funds. Instead, top holdings include companies such as LED light manufacturer Cree (CREE) and cancer-fighting startup NovoCure (NVCR). The ETF comes with an ultra-low annual expense ratio of 0.04%, or $4 for every $10,000 invested.
