I make money. No, trading costs are max $8 in, $8 out. $16 on a $20,000 or $200,000 turn around is not that much.
I substantially beat mutual funds for the last 5+ years. This year my funds are doing great - mainly because I've learned a lot more about picking the right sectors and funds. So it will be closer than usual.
Up to you Kloppit. If you don't want to take the time, then get some good very low cost funds. Remember - don't buy into the ETF hype any more than any other hype. I use some selected ETF's and some low cost funds.
I use a combi investing technique. Pure science to pure popularity. Charts are great, but they are NOT the be-all end-all. If you can execute fast enough, nothing wrong with turning $200 -500+ in a day trade.
The bottom line - it's almost always better to be an owner than a lender. Notice I said almost - you need to lend some money, too. I like a couple bond ETF's and a STBF for that!
Good question though - a trader/investor should never lose sight of it.
