During bull markets, often the best way to trade is to go with the momentum. That's usually the route I like to take, but there's another way to trade that can also net you big results.

That is to identify sectors that have come under fire that have the potential to move much higher -- that is, value trades. The multi-national industrial mining sector fits this bill.

One great way to invest in this sector is with iShares MSCI Global Metals & Mining Producers (NYSE: PICK). This exchange-traded fund (ETF) holds the biggest industrial mining companies, including BHP Billiton (NYSE: BHP), Freeport-McMoRan Copper & Gold (NYSE: FCX) and Rio Tinto (NYSE: RIO).

Although PICK is down 12% year to date, the fund has seen some strong buying during the past four months, rising 27% since its July 5 low.
