I'll let you in on a secret. In one of our Material Profits issues, I recommended PowerShares Wilderhill Clean Energy ETF (PBW:AMEX), and we've been having trouble with it ever since. It's always difficult buying near the top, as we did with PBW back in mid May.

We did foresee a slight pullback, but when the whole market got slammed, PBW fell a lot further than we anticipated. Not even higher oil prices, which PBW had been moving in lockstep with, could pull this ETF back above its 200-day Moving Average.

And yet, PBW has continuously rebounded to that level. In the past six months, PBW has tested its 200-day MA no less than ten times.

Now, we're trading just below it, with higher lows and higher volume. It looks like we're gearing up for a breakout. And that's all PBW needs - enough momentum to get back above (and stay above) its 200-day Moving Average.

In all, PBW remains one of the best sector plays in alternative energy, and moving forward into 2007, you'll see it garner a lot more attention. Just look at how volume's been increasing since October. Average daily volume was 214,000 on October 2. December 14's volume was 379,400, with peaks of more than a million in between.

Hang on to PBW, and watch for a pop once it regains the 200-day MA.
