as far as i know, BOE is 50% US exposure. before it merged with BWC and BFD, i think it was more "international". maybe the blending of the three brought it more US based positions.
i like the covered calls aspect, a good hedge. i imagine the mgrs are looking at buying some calls back right now. i don't like PBP (covered calls on SPY), i don't think that one every buys calls back. when you play with covered calls, you need active mgmt. buy them back at a gain or buy them back at a loss but immediately write the same number of calls further out on exp.
I looked at the holdings of BOE also today, and was relieved to see that, despite the "global" in the title, it's mostly U.S. I also like the covered call funds right now, as I think they are more defensive in a market like this.
I'm out of all the AOD's, AGD's, and ADVDX's. I thought they might do okay in a bull market, but right now we don't know what we're in.
