I remeber the Sykes saga. I think he was then runninig Xl discount petrol and came out in public round about 1985 and said the then bull market was overdue for a collapse of historic proportions. He put his money where his mouth was, but unfortunately took a massive position in the futures market.
To call a market down is one thing, to put a time on it is another. And this is where these prophets always seem to come unstuck.
Russell, or was it Adam Hamilton at Zeal Intelligence says somewhere, very plainly, not to take positions in time denominated instruments like options /futures... but to get the underlying physical, be it shares or coins or whatever. That removes the time constraint.
As it turned out Sykes was eventually right...but broke.
