Quote from z32000:
warren buffet says, it's easier to make larger gains with smaller money...
and harder with large amounts of money...
can anyone try to guess or elaborate on this... is he just refering to excess volume? are hedge fund managers allowed to throw all their money into one stock or futures at one time and get out within seconds...
I'm making good money in futures....I wonder if I had a lot more money to play with, would it be a lot harder to execute my orders with larger contracts?
It's all a question of liquidity. And you don't have to be managing billions to run into this problem.
For example, assume that I am trading a stock (ticker ABCD) and want to buy it now at $32.15 per share, with an expected return of $0.02 per share (based upon past trading experience and/or valid backtesting with the strategy being used). If I'm trading 200 shares, I easily buy at 32.15, and subsequently (on average) sell some time later at 32.17, and make $4 profit minus a few commission fees.
However, if I wanted to buy 20,000 shares of that stock the result would be decidedly different. While I might get the first few hundred shares long at 32.15, I might have to chase the stock up to 32.45 to get my full 20,000 shares, perhaps averaging 32.30 per share. When my sell point comes, I might get a few hundred (or thousand) shares at my intended price, but to fill the full 20,000 shares I will end up pushing the price down based upon my own selling, and my average sell price might be 32.05.
The final result? Despite the identical buy and sell times but due to my much larger trading size, I lost $0.25 per share, or $5000 on the same trade that would have netted a profit on the smaller scale.
Trading large size is much, much more difficult than trading small. It is an excellent advantage that retail traders typically have over hedge funds.
