i have followed 4 of the 6 on this list of the past couple years.George Soros,Jim,Sam zell and mark faber made their names and a lot of money making one or two big bets.If you listen to most of them today you probably have lost money following their market calls because they have been so wrong.
Jim Rogers has touted commodities now for a long time but even with the global money printing commodity prices are relatively stable compared to what they were during other money printing periods in history.You should ask yourself why crude oil has not gone to 200 ; the answer is simply because demand would fall like a rock and that would send the prices crashing like 08

mark faber is the doom and gloom guy and he has always been more bearish than bullish and lately he has been getting bullish near market tops hence becoming a contrarian indicator for some big players.As history will show you over the years markets rise more than they go down.

Sam Zell again made a lot of money in real estate and REITS but his game has been off the last few years as the money printing and regulations create huge volatility in the markets.I heard him about a month ago say that the US govt should let the eggs break for some people meaning the current administration should stop giving money to banks to prop up their balance sheets hence avoiding foreclosures on distressed borrowers which if that was the case the housing market would go down another 20%.Your guess is as good as mine why he is a big Romney backer because that is exactly what Romney would do and Sam Zell would get a lot of real estate on the cheap.
