SECTION 1: ECONOMIC FACTORS AND BUSINESS INFORMATION
(8%) (Questions 1-8)
Question 1
Which of the following is considered a leading economic indicator?
A) Gross Domestic Product (GDP)
B) Stock market performance
C) Consumer Price Index (CPI)
D) Unemployment rate
Correct Answer: B
Rationale: Stock market performance is considered a leading indicator because
it tends to change before the economy as a whole changes. Leading indicators
predict future economic activity. GDP (A) is a coincident indicator—it measures
current economic output. CPI (C) is a lagging indicator (inflation typically lags
economic cycles). The unemployment rate (D) is a lagging indicator because
,employers tend to hire after economic recovery begins. Leading indicators help
forecast future economic conditions and are essential for investment planning.
Question 2
A company has current assets of $500,000, current liabilities of $250,000,
inventory of $100,000, and total assets of $1,200,000. What is the
company's quick ratio (acid-test ratio)?
A) 0.4
B) 1.6
C) 2.0
D) 4.8
Correct Answer: B
Rationale: The quick ratio (acid-test ratio) = (Current Assets − Inventory) /
Current Liabilities. Quick ratio = ($500,000 − $100,000) / $250,000 = $400,000 /
$250,000 = 1.6. The quick ratio is a more conservative measure of liquidity than
the current ratio because it excludes inventory, which may not be easily convertible
to cash. A quick ratio above 1.0 generally indicates good short-term liquidity.
Question 3
Under the Rule of 72, approximately how many years will it take for an investment
to double if it earns an annual return of 9%?
A) 4 years
B) 6 years
C) 8 years
D) 10 years
Correct Answer: C
Rationale: The Rule of 72 estimates the time for an investment to double at a
fixed compound rate: Years to double = 72 / annual return (%). = 8 years.
This is an approximation—the actual time is slightly longer (about 8.04 years using
the exact formula). The Rule of 72 is a quick mental calculation useful for financial
planning and investment analysis.
,Question 4
What is the debt-to-equity ratio for a company with total liabilities of $800,000
and shareholders' equity of $400,000?
A) 0.5
B) 1.0
C) 2.0
D) 3.0
Correct Answer: C
Rationale: The debt-to-equity ratio = Total Liabilities / Shareholders' Equity.
Debt-to-equity = $800,000 / $400,000 = 2.0. This means the company has $2.00 of
debt for every $1.00 of equity. A higher ratio indicates greater financial leverage
and higher financial risk. Debt-to-equity ratios vary by industry—capital-intensive
industries typically have higher ratios.
Question 5
A stock has a beta of 1.4. If the market returns 10%, the stock would be expected
to return approximately:
A) 7%
B) 10%
C) 14%
D) 20%
Correct Answer: C
Rationale: A beta of 1.4 means the stock is expected to move 1.4 times the
market return. If the market returns 10%, the stock would be expected to return
10% × 1.4 = 14%. Beta measures systematic risk relative to the market (which has
a beta of 1.0). A beta greater than 1 indicates higher volatility than the market; less
than 1 indicates lower volatility.
Question 6
, Which of the following is a characteristic of monetary policy?
A) It is controlled by the federal government through fiscal measures
B) It involves managing the money supply and interest rates
C) It focuses on government spending and taxation
D) It is implemented by the U.S. Treasury Department
Correct Answer: B
Rationale: Monetary policy involves managing the money supply and interest
rates and is implemented by the Federal Reserve (the central bank). Fiscal policy
(C) involves government spending and taxation and is controlled by Congress and
the President (A). The U.S. Treasury (D) handles government finances but does not
set monetary policy. Monetary policy tools include open market operations, the
discount rate, and reserve requirements.
Question 7
A company's price-to-earnings (P/E) ratio is 25. This means:
A) The company's stock price is 25 times its earnings per share
B) The company's earnings are 25 times its stock price
C) The company has 25 times more assets than liabilities
D) The company pays a dividend of 25% of earnings
Correct Answer: A
Rationale: The P/E ratio = Market price per share / Earnings per share. A P/E of
25 means investors are paying $25 for every $1 of current earnings. High P/E
ratios typically indicate growth expectations, while low P/E ratios may indicate
value stocks or concerns about future earnings. The P/E ratio is one of the most
widely used valuation metrics.
Question 8
What is the Consumer Price Index (CPI) primarily used to measure?
A) Stock market performance
B) Economic growth
