Q&A: T-bills Shift 
What would happen if many investors decided to sell their stocks and invest in Treasury bills instead?

EFF/KRF: Stock prices would go down and T-bill prices would go up - the usual response of prices to changes in demand. Of course, when T-bill prices go up the yield falls. Similarly, a reduction in prices caused by a large number of investors moving out of stocks pushes expected returns up.
