I agree with your purchases...you just bought a little early. When you say you are bearish on the market I believe you mean "stock" market and not the commodities markets these ETF's track. That's why you bought these as a hedge. I also think the stock market isn't finished going to the downside either.
GLD may be a little soft during the rest of the summer but I expect it come back and retest the highs we put in during March. Gold prices are seasonal and usually track oil also. GLD will probably firm up by the second half of the year.
OIL is clearly in bearish mode right now. I too nibbled on this after the 3rd straight day of declines. I think crude is going to the $120-$122 level. I'll probably be a buyer down there again. We are not out of the woods as far as high oil prices are concerned. Could we even go as low as $100 or lower? Yes, anything is possible but I truly think any move below $100 will be short lived. I think $100+ oil is here to stay unless something changes drastically (I don't see it happening anytime soon). In the meantime India and China continue to consume more and more. There are fundamental supply / demand issues at work here that we have been ignoring for decades. Any solution will not be quickly implemented.
UNG is usually bearish this time of year (July through mid-August -- unless we get a storm that enters the Gulf of Mexico). UNG may pull back further having said this. Like someone else who commented, I like CHK, DVN, APA and natural gas companies at these levels. These stocks have been hit hard this month. I have 600 shares of CHK and will buy more if they dip lower. I prefer natural gas company shares to the ETF that tracks natural gas. These will "POP" more on any good news (i.e. major discoveries, etc.), the ETF will not. I'm ready for storms and the impending rise in natural gas price that will occur beginning later next month as people look toward the winter heating season and while cooling demand is still high.
Your purchases will be winners sometime again. Hopefully you didn't use up all of your capital with these purchases!
