Campus protesters are using publicly available data to identify investments with ties to conflicts and urging schools to divest from them. By examining securities filings like 13 F filings, they can see where college endowments are invested in public stocks such as Amazon and Google. The protesters aim to influence schools to divest from companies with contracts related to conflicts, in this case, the war between Hamas and Israel. However, it is noted that the information students can access in these filings represents only a fraction of the schools' complete investment portfolio.
