>There is no basis for returns to "go down as numbers go up" Sorry, but he is correct. If you buy $1000 of a stock, it's a drop in the bucket, it changes nothing. You can buy it and sell it back all day long. Get in quick, get out quick. If a pension fund manager needs to buy $1 billion worth of a stock, the stock's price will have a massive move. It might take weeks or months for the manager to accumulate the required shares. The guy trading $1000 can ride the wave of the fund manager. If the little guy is able to detect that a bigger guy is consistently buying, the little guy can take advantage of that over and over. The bigger guy doesn't have that option to ride the wave of someone bigger.
