There are two future states and three securities with the associated payments matrix (states by securities)
$Q = \begin{pmatrix} 10 & 8 & 18 \\ 10 & 2 & 12 \end{pmatrix}$
The first security current price is 9, the second security current price is 5 and the third security current price is 14. Are there any arbitrage opportunities?
Hint: the calculations do not require matrix inverse.
Select one:
No, all securities are fairly priced and there are no arbitrage opportunities
Yes, there are arbitrage opportunities
The market is incomplete, and therefore it is not possible to answer this question
