Kol12:
If my understanding is correct would you actually need to invest quite large sums of money in stocks to make short term gains on the NZX? Looking over some company price histories it seems stocks on the NZX don't go up a heck over short term periods, the data I'm seeing is around $1 over a years period. Remember I'm completely new to the NZX so my observations may be wrong, but it does seem like you'd need to hold stocks for some time to make useful gains, at least on the NZX...
Regarding Sharesies Smartshares came up as being the main place to go for ETF trading but I will check out Sharesies again.
Wrong. Your looking at % gains. Whether thats $50 or $50,000, you want a % gain.
On reflection, your keen on some short term trading, but you cant look at that as SHORT. You can invest in BNZ or another blue chip, or a second tier or overlooked third tier stock, but forget about big % over short term. It can happen and does, but you want growth, not L+M Oil at 3c today and 5c in two weeks.
