mark whether each of the following statements is true or false. (a) Consider a stock whose required return is higher than the risk-free return. Then, in a binomial tree, the real probability of an increase in the price is higher than the risk-neutral probability of the increase. ( TRUE / FALSE ) (b) In the risk-neutral valuation, we penalize risk by changing the probability. ( TRUE / FALSE ) (c) By setting u = eoVAt and d = e-oVAt in a binomial tree, we can make the stock return required by risk-averse investors the same as the risk-free return. (TRUE / FALSE )
