Consider a borrow$-$and$-$invest strategy in which you use $$1$ million of your own money and borrow another $$1$ million $($at the t$-$bill rate$)$ to invest $$2$ million in a market index fund. If the risk free interest rate is $5\mathrm{.}74$ percent and the expected rate of return on the market index fund is $13\mathrm{.}99$ percent, what is the expected return on this borrow$-$and$-$invest strategy?
