You all can worry about whatever you want to worry about. You can follow the bulls or bears, day traders or CD holders, Wall Street pundits or the guy next door, it does not matter to me. I am looking for opportunity in the rubble.

If you are a true investor, you have a watch list -- when there is fear and negativity in the market like there has been the past few days, there will be opportunities. It is not a time to jump in with both feet, and it is not a time to speculate. It is a time to pick and choose among the companies and stocks you know well.

I would like to own more Intuitive Surgical (NASDAQ: ISRG) but it has run up so fast it has escaped my grasp, although I sense an opportunity is in the wings. I would like to own more Anglo American PLC (NYSE: AAUK) but it jumped up after recent acquisition talks in the mining industry and has not settled down yet. And it may not, but I will be patient. My regular readers know I love Huaneng Power Intl ADS (NYSE: HNP), which hardly moved today but has come down significantly in the past week, and that is very, very tempting.

Since the China meltdown last week; and all the turbulence in world markets; and Greenspan and Bernanke comments; and this weeks recovery of half the losses ... I came back to my terminal after taking a break for a couple of days to find good news.

Since my post Chasing value: Aluminum Corporation of China ADS last week, (NYSE:ACH) has continued to recover and is now up considerably. Having a buy order in at a 20% discount to a bargain, execute, and go up after scooping me up and keep on going in a positive direction is delightful. REALITY CHECK: Yes It could dive again just as fast!

But there is a lesson here. Investors that do their own stock picking must have a watch list, be patient, and be willing to act on their predetermined evaluation no matter what dumb things happen in the market. ACH was a bargain at approximately $27 per share but I do not feel comfortable buying when a stock is at an all-time high. However, at $22 my buy order triggered and I picked up a bargain that closed today at $24.35. If I was a stock trader I would take my 11% profit in 4 days and run. As a buy-and-hold guy I'm keeping this one for the long haul. ACH has a 5.4% yield with a P/E of 8.4. If the stock goes nowhere the rest of the year. I will have a 16.4% return -- very nice, but I see the demand for aluminum in China continuing to increase for the next few decades and this stock as one of my best picks ever.
