This blog post is referring to a very old study of Closed End Funds (CEFs) that I read this year. CEFs are the equivalent of what Australian investors usually refer to as ASX Listed Investment Companies (LICs). The study discusses in detail the typical life cycle of CEFs. It talks about why they often swing from premium to discount, and then back to NAV in a fickle manner.
