You may want to see if your online broker will allow you to invest in US shares. One of our subscribers uses Stocktrade, through a nominee account, to do this. US shares can be more active than UK shares, they tend to have a higher volume and you have more companies to choose from. You will find a greater range of share price too. If you trade in the UK you will normally buy shares from just a few pence up to £20 or so. On that, be careful when buying shares in the pence range due to their volatility. US shares, on the other hand, range from several hundred dollars to cents. Normally we would not consider a share below $10. Remember, the share price does not reflect the value of the company. The Brits seem to prefer a lower share price. But holding 10 shares in a US company and 100 in a similar UK company has no advantage or disadvantage for you other than the feeling of holding fewer shares. If the share price goes up or down it is still going to have the same relative effect on your fund.
