What is a firm's intrinsic value? Its current stock price? Is the stock's "true long-run value" more closely related to its intrinsic value or its current price?

Are all corporate projects equally risky, and if not, how do a firm's investment decisions affect the riskiness of its stock?

If most investors expect the same cash flows from Companies A and B but are more confident that A's cash flows will be close to their expected value, which should have the higher stock price? Explain.
