If trading the more liquid stocks (hence 'more volatile'?), then expectation is higher rewards v. higher risks. If you have small trading capital, then you may not be able to trade many of these stocks?

With spread betting you can trade decent lot size but as always, leverage is a double-edged sword. You must manage risk, otherwise your one bad trade could wipe you out.

More liquid does not mean more volatile. In many cases, just the opposite as it means a price will almost always be found without to much gapping intraday.
