Cloudy day, sleepy day

When I wake up and look outside and the sky is overcast, I just want to stay in bed. That's not to say I don't like a cloudy day every now and then, but I prefer them when I'm curled up in bed. However, I'm not in bed right now. I'm at school. I'm about to read about the effect of risk on the valuation of both a firm's assets and its stock. More of a finance reading than a law reading, but you've got to get the background stuff out of the way before you can delve(sp?) into the law.
