One other thing to bare in mind about spreadbetting, is you get charge "interest" on the value of the share you are buying. Personally, I have lost money spreadbetting, and when it comes to investing a good thing to remember is you don't have to be good at everything, do the things that make you money and don't worry about what you can't do. You still get Dividends though (short people pay them but get interest with some services), so if you pick the right firms you can use spreading long time and use the dividends to cover the costs. However shares do fall when they go X-Dividend.
Personally I have a self select ISA (with iii), ok there is a 10 pound fee (+ .5% stamp duty on buys) however you can keep holding things forevever without fees (in this service). Also do not forget a 10 buy fee also requires a 10 pounds sell fee. This is also tax free and you can pay in over 10k a year (not that I have that much spare capital).
Return on a 10% rise
250-(10+1.250) = 238.75*1.1 = 262.625 - 10 - 250 = 2.625 (not much of a profit there) 1%
### 250-(2+1.250)= 246.870*1.1*.1 = 271.56 -2-250 = 19.56 (7.8%)
500-(10+2.50)= 487 *1.1 = 536.2 -10 -500 = 26.2 pound profit (5%)
1000-(10+5) = 985 *1.1 = 1083.5 -10 -1000 = 73.5 pounds profit (7.5%)
2000-(10+10) = 1980*1.1 = 2178.0 - 10 -2000 = 146 pounds profit (8%)
4000-(10+20) = 3970*1.1 = 4367 - 10 -4000 = 357 pounds profit (8.9%)
This is why I invest 1000-2000 pounds in one go, normally 2000 for an initial investment adding in units of 1000 pounds if I feel like it, as it allows me to name the price I want to trade at. With a small amount like 250 pounds your need to use a low fee service when they pick when to buy and sell, so you can pick the day but you will not get a good price (the always seem to work out how to get the worse deal on the day).
Personally I have reduced my exposer to the market about a 1.5 years ago and mostly just have the money I have made from previous gains.
IANAIFC, don't risk money you can't afford to lose or may need back in a hurry, it can however be great fun, and if your an optimist now could be a good time to start, I have bought some RIO tinto, in the big fall, having previously sold mine at £40+ and got back in at £31 (yes could have done better but its for the long term).
iii has great forums,
Shareprice has real time streaming for free and
ADVFN has the best portfolio management too.
This might look like I am a buy and hold person... I am not... A profit is a profit is a profit is not a loss its a profit... take them when available. A good why to think about if you sell is how many years dividends you can have NOW... and how long do you think you will have to wait to buy those shares (or something else as good) again... Other things you can do is, get your stake money back and keep the change in shares and let it ride (not so good with small ammounts).
For some (like TheAnimus) its a good way to make a living, for other like me its a fun hobby that pays for itself.
