THINKING AND PROBLEM SOLVING 7. Your brother calls you on the phone telling you that Google's share price has fallen by about 25% over the past few days. Now you can own one small slice of Google for only $540 a share (the price on the day this question was written). Your brother says he is pretty sure the stock is going to head back up to $700 very soon and you should buy. Should you believe your brother? (Hint: Remember someone is selling shares whenever someone else is buying.)
