How do you manage risk like what we are experiencing now when your position has a longer time horizon, say 2-3 months or up to a year (sort of semi buy-and-hold)?
Risk grows as time passes. Do not measure the situation relative to the beginnning of your position; measure repeatedly, what the market is doing. Your positions are only based upon NOW and which side of the market is controlling. Long term income runs at about 4% a week.
I don't think it is true. To be a good trader you need to understand how people invest long term. The best way to understand it is to do it yourself.
