But in most cases, I think I have a better chance at limiting risk (and ideally boosting returns) by sticking with open-end bond funds like DoubleLine Core Fixed Income (DLFNX), DoubleLine Total Return (DLTNX), Thompson Bond (THOPX), PIMCO Income (PONDX), and PIMCO Foreign Bond US Hedged (PFODX).
In repositioning their assets, the M100 took a marginally bullish though heavily hedged stance, pouring cash into both the iShares Lehman 10-20 Year Treasury Bond and, to a lesser degree, into Ultra Industrials ProShares, and ETF that moves at a rate double the amount of change in the Dow Jones U.S. Industrials index.
