You might have heard of Sell in May and Go away right? A co-ordinated sell of stocks, causing a domino effect as stoplosses are breached.
Well there must be groups of investors in the web which plan weekly/monthly co-ordinated efforts to short or buy stocks all in one go by using CFDs. The combined effort of say 1000 investors with a leverage of £10,000 each (with only £1000 CFD deposit) can possibily make the market swing if they all sold or bought shares at the same time. With a spreadbet account also running you could profit by having shorts or buy orders set to "catch"this price movement.
I am sure the big institutions do this - as teams of investors always are better than a individual private investor going it alone.
PM me if you know any groups
If there isnt one - i might start one!
