at £13.40 a share i'm not sure his £200 investment will see a lot of return ??
I invested some money a few years back and split it over various shares ( even made money on the Villa takeover , bought at £2.19 , got out at £3.30 Thanks Randy :-) )
most of my purchases are based on picking up snippets on the news or forums or sensing that something is "good value" ..I.e I invested in BP just after the oil leak when the share priced plummeted ... currently up around £1.20 a share on that deal .. took a punt on RBS at 24p a share , sold at 45.93p just over 2 months later , took the gamble mainly on the basis that the Govt weren't going to let any banks fail
if I had to punt now something like BSkyB would be one that I would be doing my homework on ... recently £8.50 a share now trading at £6.99 a share ... read up on them and try and figure are the shares likely to dip a bit further and then you can get in and invest for long term or work out if the share price will have a short term spike / rally on Pension funds and other speculators snapping up at what they feel is a good price and making a quick profit .. and if you find the secret and can get it right each time then put it in a bottle and sell it :-)
of course not all deals return a profit but hopefully your good deals will outweigh your bad ones ... the trick is not to get carried away and invest money you can't afford to lose ... Usually i set an out price and I am very good at sticking to it , a small profit in the bank is better than a huge paper profit that then disappears overnight
