The reason I asked, is that a friend does it, as an alternative form of gambling, and it came up as a subject in the pub the other day
the shares he trades in are very low cost, 5p 10p 20p values and it is more a hobby than a get rich scheme, though of late he seems to have done rather well out of it
ive googled it and it doesnt seem that risky, and noticed that a lot of people do it as a common share club, investing, risk taking and profit and loss on a communal basis
it looked interesting
