4. When a public company announces its profits each quarter, the price of its shares can change dramatically if the profits exceed or fall below expectations. Why does this happen and what does this tell you about the time horizon for decision making within companies?

The price of a public company's shares can change dramatically when it announces its quarterly profits because these announcements provide new information about the company's financial health. If the profits exceed expectations, it suggests that the company is performing well, which can increase demand for its shares and drive up the price. Conversely, if the profits fall below expectations, it suggests that the company is underperforming, which can decrease demand for its shares and drive down the price.

This phenomenon tells us that the time horizon for decision making within companies is often short-term. Companies are under pressure to meet or exceed profit expectations every quarter, and decisions are often made with this quarterly timeline in mind. However, it's important to note that while this short-term focus can drive up share prices in the short run, it can also lead to problems in the long run if it results in decisions that are not in the best long-term interest of the company.
