5 Must Know Facts For Your Next Test

  1. Stocks can be classified into two main categories: common stocks and preferred stocks, each with distinct rights and privileges for shareholders.
  2. Investing in stocks carries risks, including market volatility and potential loss of investment; however, over the long term, stocks have historically provided higher returns compared to other asset classes.
  3. The stock market is influenced by various factors such as economic indicators, interest rates, and corporate performance, which can all affect stock prices.
  4. Investors often use the price-to-earnings (P/E) ratio to evaluate whether a stock is overvalued or undervalued compared to its earnings potential.
  5. Understanding the intertemporal capital asset pricing model (ICAPM) helps investors assess how stocks are expected to perform over different time horizons while considering risk factors.

Review Questions

  • How do stocks contribute to an investor's overall portfolio strategy in terms of risk and return?
    • Stocks play a crucial role in diversifying an investor's portfolio by providing potential for higher returns compared to more conservative investments like bonds. They introduce a level of risk due to market fluctuations but also offer opportunities for capital gains and dividends. By carefully selecting stocks based on their risk profiles and growth potential, investors can balance their portfolios to achieve desired levels of risk and return.
  • Analyze how market volatility can impact stock performance and investor behavior during economic downturns.
    • Market volatility can lead to significant fluctuations in stock prices during economic downturns, causing fear and uncertainty among investors. This may result in panic selling as investors seek to minimize losses, which can further drive prices down. However, some investors may view volatility as an opportunity to buy undervalued stocks, believing that markets will eventually recover. Understanding these dynamics is essential for making informed investment decisions amid uncertainty.
  • Evaluate the implications of the intertemporal capital asset pricing model (ICAPM) on stock valuation and investment decisions over varying time horizons.
    • The intertemporal capital asset pricing model (ICAPM) suggests that the expected return on stocks is influenced not just by their current risk but also by future investment opportunities and consumption preferences. This means that investors should consider how changes in economic conditions could affect stock valuations over different time horizons. By evaluating stocks through the lens of ICAPM, investors can make more informed decisions about when to buy or sell based on anticipated changes in market conditions and their own financial goals.
