At current levels I could see buying GG for a snap back to prev low retest and top of trend line for about a 10% move. Buying at or close to the low's here gives you a nice a nice R/R ratio.
NOTE - Goldcorp bounced/consolidated at almost each fib level previously ("1", "2", "3", ...) and at the lows I believe it would have a book value of less than 1.
