I have $5000. I'm looking to invest at 100:1 in US 500. I would like to place my investment and forget about it, so I'm willing to tolerate a 15% price fall, on the premise that it will eventually go back up (like what happened with the war on Iran, for example). Accordingly, I'm looking to invest 300\*100 = $30000.
Am I thinking straight? Would you have anything to correct?
