From Yahoo Finance:
Teachers are far more patient than other investors. They only traded 6.1 times per year, compared to the average investor, who traded 9.1 times. This should come as no surprise. Plenty of research has shown that passive investing trumps active investing on a pretty consistent basis.
Teachers aren’t sold on individual stocks. Openfolio found that teachers are much more likely than the average investor to invest in mutual funds than in single stocks — a more diversified approach. About 52% of teachers invested in mutual funds, holding the rest of their investments in individual stocks. The average investor held 46% in mutual funds and 54% in individual stocks. While Openfolio does not reveal the exact brokers its investors use (for security purposes), they estimate that teachers invest 10-20% more through 401(k)s than through self-directed accounts (like a brokerage account with E*Trade) when compared to the average investor.
