Have you traded JNUG? It's the triple for the junior gold miners, and is volatile as hell. Check it out.
The OP wants to trade vehicles that are moving more or less in tandem with futures so XLE or OIH would not qualify.
True, /CL doesn't trade according to the moves in XLE/OIH. USO is more representative of the crude futures contract, however as long as it's prop he won't get the separate K-1, the firm will. The OP was asking about why the miners don't synch with /GC. As you stated, GLD is more in line with the volatility of a /GC move.
Yes, they are incredibly volatile... I'm still working on my discretionary systems and I'm not doing very well with these volatile miners stocks. I'm looking for something that mirrors the futures contracts. Looks like I'll be trading GLD (is there something cheaper?). GDX would be a good fit for me but like the other miners ETFs, it doesn't always move in tandem with the front month's futures contract.
NUGT moves well and is not as volatile as DUST. NUGT doesn't seem to have a lot of correlation with GC. Especially today, GC opened down a lot compared to friday's close and NUGT opened at friday's close.
