Question

In the market for Amazon.com stock, explain how each of the following events, ceteris paribus, would affect the demand curve for the stock and the stock's price. a. The interest rate on U.S. government bonds, an asset considered safe from default, rises. b. People expect the interest rate on U.S. government bonds to rise, but it hasn't yet risen. c. Google announces that it will soon start competing with Amazon in the market for books, DVDs, and everything else that Amazon sells.

Short answer

An increase in interest rate on U.S. government bonds, or just the expectation of it, would likely decrease the demand and price of Amazon.com stocks as investors might find government bonds more attractive. Moreover, anticipated competition from Google is likely to further decrease demand and price of Amazon.com's stocks due to potential performance threats.

Step-by-step solution

Interest Rate Increase

An increase in interest rate on U.S. government bonds will make them a more competitive investment option relative to stocks. This is because higher interest rates can lead to higher returns. Thus, the demand for Amazon.com stocks will decrease, leading to a downward shift in its demand curve as investors shift their capital towards government bonds. Consequently, the price of Amazon.com stocks may drop due to the reduced demand.

Expected Interest Rate Increase

When people anticipate a rise in interest rates on U.S. government bonds, they may start shifting their investments in preparation, even if the rates haven't risen yet. Similar to the previous scenario, this expected change might result in lowered demand for Amazon.com stock, leading to a drop in its price.

Increased Competition

If Google announces competition with Amazon on several products, it can create uncertainty about Amazon's future profits. This potential threat to Amazon's profitability can also deter investors, resulting in a decrease in demand for Amazon.com's stocks and thus, a lower stock price.

Key concepts

Interest Rate Effect on Stocks

Understanding the relationship between interest rates and stock prices is fundamental in the financial world. When interest rates on low-risk investments like U.S. government bonds increase, these bonds yield higher returns, making them more attractive to investors. This attractiveness is in part due to the 'risk-free' nature of government bonds, which stand in contrast to the higher risk associated with stocks.

As interest rates rise, the opportunity cost of holding stocks becomes higher. Investors often reassess their portfolios, and some shift their focus toward these bonds to capitalize on the increased returns. This shift in investor behavior causes a decrease in the demand for stocks, which leads to a downward movement of the demand curve in the stock market for companies like Amazon.com. Lower demand typically reduces the stock's price, as investors are not willing to pay a premium for a security that offers lesser returns compared to newly high-yielding bonds.

Moreover, the anticipation of higher interest rates can mirror the actual interest rate increase in its effect on stock demand. Even before interest rates rise, if investors expect them to go up, they may pre-emptively move their funds away from stocks toward bonds or other assets, which can lead to a similar decrease in stock prices. This phenomenon highlights the importance for investors to keep an eye on not just current rates but also on the market expectations.

Investment Demand Shift

Market sentiment and investor expectations play a crucial role in shaping investment demand. The stock market, a forward-looking entity, often reacts strongly to expectations about future economic conditions. Take the example of the potential rise in interest rates for U.S. government bonds. Even if the actual increase hasn't occurred, the mere expectation can cause a shift in investment demand.

Investors may seek to reallocate their portfolios ahead of expected changes to optimize returns, effectively causing the demand curve for stocks to shift. This pre-emptive behavior is a strategic move to safeguard or enhance portfolio value based on anticipated market dynamics. It's a shift in demand driven not by the actual event, but by the expectation of the event—an essential distinction that can have significant implications on stock prices.

The investment demand shift can also be affected by several other factors, including fiscal policy changes, global economic events, and technological advancements. This shift is always in motion, constantly being influenced by the changing tides of economic news and investor sentiment.

Competition Impact on Stock Prices

Competition within industries is another vital force that affects stock prices. In our case, if a tech giant like Google announces intentions to directly compete with Amazon in core areas such as books and DVDs, investors might become concerned about Amazon's ability to maintain its market share and profitability.

Increased competition generally implies tougher market conditions and potentially reduced profits. For a company's investors, that's a warning signal that the future financial performance of the company may not be as rosy as once thought. As a result, their valuation of the company’s stock might decrease, translating into a lower demand for the company's shares on the stock market. This decreased demand leads to a leftward shift of the demand curve and often ends in a lower stock price for the company facing heightened competition.

It's critical to understand that this effect can vary in magnitude. Factors such as the entrant's market power, the targeted market segment, and the incumbent's response strategy all play a role in determining the overall impact on stock prices. Keeping an eye on competitive movements is therefore an important part of any investor's strategy.
