Proshares and Ishares have very good ETFs I use for exposure to commodities, indexes, the VIX, currencies, etc.
As far as being long on commodities and shorting the broad equity markets, I'm down upper single digits to low double digits overall on those portions of my portfolio YTD. I'm up low double digits on crude and pretty much down somewhat on things like gold, silver, nat gas, platinum, etc. Up slightly on a small palladium position. Still holding lots of cash, and have been selling off more and more of my long positions in the last 11 months.
I had a short on HLF about a year and a half ago that I held a few months that did well for several months. I covered completely and got out once Ichan and others started getting in long. But I recently bought a put on it, along with puts on TSLA, JCP, and NFLX (which I also still have a small long stock position in).
I had been long on AAPL for years, but sold most of it early this year. But I recently bought more.
I've largely gotten away from long positions on very many stocks, but I have done well YTD on a limited # of holdings.
I have had long positions in: IEP, UHAL, BIDU, RGR, SWHC, AWH, BPL, OUTR, FRX, ECPG, CBST, CHK, XIN, GPOR, EOG, ROST, AIRM, ANDE, ANW, CLR, and a few others here and there.
And you always get hosed here and there on a few, of course. CTXS got pounded good a few days ago.
A few bucks in very speculative holdings: CVVT, AMAP, VNET, GGAL, AIR, CYOU, DQ, BLDP.
Sold the little LNG I bought several years ago after a great run it's had. Also sold GTAT after a great run up YTD. CYH too.
Made a killing earlier in the year on a short term buy of EBIX after it lost over 50% in a week on some scandal that seemed minor and isolated and seemed to quickly blow over. The stock quickly recovered, then shot up on news that GS bought them out a short time later. I thankfully sold out completely on that news, then the stock soon dropped again when the sale did not go through due to some sort of accounting irregularities.
