Will a small investment in a company net a worthwhile gain?
If you bought 5 shares @ $20 each that would cost you $100 plus brokerage. Even if your brokerage was only $10 in and out, your shares would have to go up 20% just for you to break even. You don't make a profit until you sell, so just for you to break even your shares need to go up to $24 per share. Because your share holding would be so small the brokerage, even the cheapest around, would end up being a large percentage cost of any overall profits. If instead you had bought 500 shares at $20, being $1000, the $20 brokerage (in and out) only represents 2% instead of 20%. This is called economies of scale.
