While I'm a realistic/optimistic long-term holder, not sure if we're going to see that much of a jump.
We might see a little bump, but the rate cut is already priced into the market. I'm sure there are many short-term holders who hope there's a jump. If FCX drops, they have a stop-loss limit. If the stock really bursts up, they'll take profits thereby preventing/slowing further daily appreciation.
IMO, there are certainly opprtunties for day traders and short-term holders, and while a select few of these will make great returns, the best return w/ less risk will come to long-term holders.
