. Suppose you are considering building a factory that produces generic steel chains. Price of a typical chain right now is $175. Next year the price could go up to $200 or go down to $160. Each is equally likely. Cost of factory is $900 today and it can be built in a few days since you have infrastructure in place. So the cash flow starts in the same year. Should you invest today or wait for next year? WACC is 12%. Invest today Not enough information to answer. Both give the same result Wait and see next year
