There was also this thing about them being my 'sponser' whereby all my shares are kept in this Commsec portfolio rather than 'being scattered at individual companys', if i was to say have shares in 5 differnt companies.
If I'm reading your post correctly, the 'sponser' thing is refering to CHESS. CHESS (or Clearing House Electronic Subregister System) basically consolidates your holdings under one HIN. You can read more about it
http://www.asx.com.au/products/shares/how/chess_faq.htmWho has shares? What's the best way to buy/sell them. I've been doing some investigating and I probably should have started this thread prior to my actions but I made an application to Commsec to use them as my broker (I think thats what they do) lol.
Unless you have a large sum of money, or are willing to negatively gear (the ideal scenario), then you won't be 'buy/sell(ing)' unless you want to destroy your capital. On Comsec, brokerage is $30 a trade, so thats $60 for buy and sell - which is 12% on a lot of $500.
Comsec is a respectable broker, and if I was going to use an online broker, it would definitely be Comsec or E*Trade
Before putting any money into the market, I would have a read of anything investment related you can get your hands on. I would also have a look at some different markets. From your post (I may be totally wrong here) you seem to want to 'day trade'. If thats the case, I would check out the Forex market. Forex brokers don't charge brokerage (in the traditional sense), but rather have a 'spread', and all offer leverage, some upto x200. Oanda is a respected online broker, and also has 5sec charts, which means you can scalp without having large capital.
