Answer
Some real rubbish being spoken here. you can buy a single share if you want, but by the time commisions are paid this isn;t economically viable. minimum investment without using leverage should be £30k otherwise you are going to make next to nothing doing it. using leverage such as a s/bet or future you could start with a much smaller sum. would not touch a stockbroker if you paid me. most could not tell you a nice stock from a bad one and rely heavily on buy/sell notes issued by analysts at major institutions. where you live is largley irrelevant. but do your own research, get on line and buy with the lowest com rate.
