If we knew this we wouldn't be mucking about on this chat. Why small stocks? You can make good gains on all size (priced and MC) stocks. I would take care not to put complete faith in posters here or anywhere else for that matter. Be wary as soon as people start posting things like "MM's playing with a share", "wot no RNS's" or "will be RNS soon" and other things trying to justify share movements. If you want look at some young companies that might take off, like in green energy, tech, anything innotative. Read lots, notice things, listen to Radio (4 for me but any not playing just music). If you get some good service or like the idea of things, see if you can get shares in the company and then do a bit of thinking and maybe buy some. Don't over commit, gain experience by winning and losiong but in small amounts.
I’m new to this too, only been frequent trading for two months. Very very wise words from nezlob. Don’t get sucked into hype regarding small stocks. 95% of my portfolio is in medium to long holds of well known FTSE companies and I’ve made about 20% plus dividends over the past year. Not stunning, but much much lower risk. However, again read up on things. Even with reading up, I’m currently down 10% on my 2 months of AIM and small cap dealings - so let that be a warning to you:). Good luck!
