Differentiation
The stock market is a perfect example of an undifferentiated market.
If you want to buy 100 shares of IBM, you will buy it at the lowest
price. There may be 1,000 people ready to sell shares of IBM. All you
care about is who will charge the least. No characteristic of the
seller—how long he/she has held the shares, whether he/she cheats
on income tax or spouse, what his/her religion is—matters to you
