Given the mining sector's weight in the FTSE 100 index, it is important that miners like Rio Tinto join in the next rally, says Warren Firth at www.globalprimepartners.com.au
I think the FTSE is heading back to 6491 and that Rio is worth buying on a break back above 3310p. Its target then becomes 3972p. By contrast, an unlikely drop below 2700p would present a major shorting opportunity.
