Last time I kept buying BHP on the way down too $20.
You can spot the bargains by looking at Forecast PE ratio's (add a factor of safety) if it comes out anywhere below 10 you have a bargain. Then checking the Current Ratio to make sure the company has cash to operate.

Worked great for MCC and GCL and some other coals companies.

I just sold the last of my MCC's shares at $16 and bought BHP at $35.80. My above method was indicating a great buy, but shes still going down. Anyway if it keeps going lower I'll buy more.
