None of the above is an example of a perfectly competitive market.
Every stock exchanges have some different features and the stocks.Some stocks listed on NYSE may not be listed on NASDAQ. The Nasdaq is the largest electronic screen-based market. It currently offers lower listing fees than NYSE,while the AMEX focuses on exchange-traded funds (ETFs).
Similarly the automobile industry is monopolistically competitive because all brands sell differentiated cars.An Audi and a Jaguar may have some similar feature but they are also different in some other aspects like designing, mileage etc.
Thus,the stock market or the automobile industry cannot be categorised as a perfectly competitive industry.
