"but those who are "fleet of foot" with high IQ stand to make far better returns than say the property investor who rents out his investment property(s)."
Yes those that can successfully flit from investment to investment can make better money than those that just sit and collect dividends from blue chip shares or rent from investment properties. But those that don't flit from investment to investment can still make a solid return over the long term. IMHO it is always best to have a combination of investments in your portfolio - the slow and steady growth assets blue chip shares/property, and an element of the speculative investment for the higher risk higher gain. The exact weighting in your portfolio will ultimately come down to your own risk tolerance.
"Warren Buffett of course is the prime example."
Yes but there only can be a few Warren Buffet in this world - the majority still have to generate their wealth the slow and steady way (not everyone can have fast money!)
"My guess is that the IQ of successful share traders would be very high."
Yes but how many are truly successful over the long term, and how many are just lucky, again I think this applies equally to all investment classes.
