Unless you are extremely rich, you won't be buying shares in upcoming IPOs until after they hit the market which means paying a premium (for example, if Alibaba's price is set at $30, about the best you'll get is $35 when the big investors cash in for their profits). Check with local stock brokers to see if they can trade on the NASDAQ.

I bought and sold shares through my local HSBC for a number of years - it's easier if you have an account with them as any money involved goes straight in or out of that account. NASDAC shares may be difficult to buy and sell for the average punter in the UK - never tried it.

From Uk, how to buy Nasdaq shares and upcoming ipo's (i.e Aliababa) in online? Also kindly advise how much they charge for each trading transaction?

Is there any nasdaq trading service from barclays or hsbc bank providers ? please advise
