NEW YORK ( TheStreet) -- I'm fuming about the shutdown of the U.S. government. I'm so angry I'm breaking out in a sweat and my face is flushed. Then I remembered that I turned the heater in my office up too high and I'm sitting in an unintentional, homemade sauna. And I'm not even Swedish, Finish or Alaskan!Now that I've lowered the thermostat I've determined not to let this unfortunate political version of "your mother is fatter than my mother" distract me from the opportunities it offers. An intelligent, emotionally disciplined investor wants to capitalize on how the government's gridlock impacts our investments and the financial markets. If you're properly diversified, use hedges, and believe in asset allocation, you're not hurting too bad yet. The S&P 500 is still above the 1,680 support level and the Dow hovers above 15,000. As important, the stocks you've been yearning to buy are slowly going down in price. Are you alert to the current price levels of your favorite "watch list" equity rock stars? Speaking of being alert, because I'm a subscriber to TradeStops, the web's premier online risk management service for investors, I received an alert telling me two stocks I've been waiting to buy are nearing my personal buy-limit prices. One of them happens to be a world leader in oil and gas rig equipment, National Oilwell Varco ( NOV). National Oilwell Varco provides the major mechanical components for land and offshore drilling rigs, as well as complete land drilling and well servicing rigs. That's a hugely profitable business. It includes tubular inspection and internal tubular coatings, drill string equipment, extensive lifting and handling equipment, and a broad offering of down-the-hole drilling motors, bits and tools. NOV, as I like to abbreviate it, also provides supply chain services through its network of distribution service centers located near major drilling and production activities worldwide. Using TradeStops I receive an alert every time NOV corrects 4% from its most recent closing price high. On Sept. 20 it hit a short-term high price of $80.27. Ten days later it fell almost 4% to $77.20.
