No, it certainly isn't mandatory. Institutional investors aren't required to buy stock in any company.
"Institutional investors, like hedge funds, mutual funds, and pension funds, are not obligated to purchase stock in every company listed on the Nasdaq. Their investment decisions are based on various factors, including their investment strategy, market analysis, and risk assessment. Institutional investors have the flexibility to choose which stocks to invest in, and their portfolios can vary widely."
"Aren't Vanguard and other institutional investors obligated to own MULN as part of their total market funds? Owning shares isn't discretionary. It's mandatory."
That would seem pretty draconian if a institutional investor had to invest in every Nasdaq company.
