Any rational quoted price for a financial instrument should: A)
| provide no opportunity for arbitrage. |
| B)
| provide an opportunity for investors to make a profit. |
| C)
| be low enough for most investors to afford. |
|
Since any observed pricing errors will be instantaneously corrected by the first person to observe them, any quoted price must be free of all known errors.
This is the basis behind the text’s no-arbitrage principle, which states that any rational price for a financial instrument must exclude arbitrage opportunities.
The no-arbitrage opportunity assumption is the basic requirement for rational prices in the financial markets.
This means that markets and prices are efficient.
That is, all relevant information is impounded in the asset’s price.
With arbitrage and efficient markets, you can create the option and futures pricing models presented in the text. |
