Sure, thanks for this question!

In case of public funds:

Depending on the jurisdiction, funds are allowed to invest only in certain securities, like stocks or bonds. In most countries, they are not allowed to use all available products; esp all products which offer high leverage (and highlosschances) are not allowed for institutionals.

A private prop trading company may do it, though they are not managing billions (as the pension fund in the article); and those prop traders in reverse can not that easily attract "other people money"
