Review Questions

• How does the Nikkei 225 serve as an indicator of Japan's economic health?
  • The Nikkei 225 reflects the performance of major companies in Japan, so when the index rises, it generally indicates that investors are optimistic about these companies' future earnings and the overall economy. Conversely, a decline in the Nikkei 225 may signal economic challenges or lower consumer confidence. Because it includes significant companies across various industries, changes in the index can provide insights into broader economic trends affecting Japan.
• Discuss how the price-weighted nature of the Nikkei 225 affects its calculation compared to a market capitalization-weighted index.
  • In a price-weighted index like the Nikkei 225, stocks with higher prices have a greater impact on the index's overall value, regardless of their market capitalization. This means that even if a company has a small market size, if its stock price is high, it will significantly influence the index’s movement. In contrast, a market capitalization-weighted index considers both price and total shares outstanding, giving larger companies more weight based on their overall market value.
• Evaluate how global events influence the movements of the Nikkei 225 and what this signifies for international investors.
  • Global events such as changes in foreign exchange rates, geopolitical tensions, and shifts in international trade policies can heavily impact the Nikkei 225. For example, if the Japanese yen weakens against other currencies, Japanese exports may become more competitive, potentially boosting stock prices and raising the index. Conversely, global economic downturns can lead to declines in investor confidence. For international investors, monitoring these global influences is crucial for understanding potential risks and opportunities within Japan's economy and stock market.
