There are both similarities and differences of faults with hedge funds and open end funds. In one sense, you're right about people tending to pile into some funds based on manager past performance.
People piled into Gundlach's funds, even though they use "exotic financial derivatives like total return swaps". (See below.) IMHO use of exotic derivatives has become more commonplace - they're not limited to hedge funds and a few offbeat mutual funds as the article suggested. Though they're still insignificant if not absent from vanilla funds.
People piled into DoubleLine, into Yacktman, and others based on the managers' long term past performance at substantially identical funds. Not on a short term (3 year) record at a fund that was substantially different. RSIVX
by design holds longer term, often illiquid bonds, than RPHYX, as opposed short term bonds ("
think 30-90 day maturity").
So ISTM there is a qualitative difference between piling into funds like RSIVX (unproven management for that type of fund) or TFCIX or WBMAX (both with untested strategies for open end funds), and piling into proven management and strategies in the hedge fund arena. Another example of a mismatch between strategies and open end funds - stable value funds. There were (as I recall) over a dozen open end stable value funds attempted. They couldn't handle the open end fund daily redemption requirement.
YACKX also floundered for its first couple of years. It was only in 1994, in a relatively flat market, that it began to shine. Yet people stuck with him. Quoting Yacktman: "My only real fear in 1993 was that people who put their money in during 1992 would take it out at a loss. I didn't want this to happen, because I knew my performance would
come back. ... As it turned out,
more money came in than went out."
With hedge funds, accredited investors have the responsibility (and supposedly the opportunity) of investigating the offering. These "sophisticated" investors don't get the same disclosures as are required of open end funds. If managers have buried past failures, it's up to the investors to discover that.
The mandated disclosures of open end funds are supposed to make it easier for the other 99%. It is their choice to accept or reject a disclosure that discloses little other than: "just trust us".
DoubleLine funds and total return swaps:
Reuters, Nov 16, 2015: RiverNorth/DoubleLine Strategic Income Fund possesses economic exposure to an aggregate of 1,103,373 shares of Common Stock [of FSC] due to certain cash-settled total return swap agreements."
ThinkAdvisor, Nov 22, 2013“It’s [DSEEX] put together using a total-return swap,” Gundlach said of the fixed-income side of the fund.
Probably other funds; this was a quick search.
