Question 62  implicit interest rate in wholesale credit

A wholesale building supplies business offers credit to its customers. Customers are given 60 days to pay for their goods, but if they pay within 7 days they will get a 2% discount.

What is the effective interest rate implicit in the discount being offered?

Assume 365 days in a year and that all customers pay on either the 7th day or the 60th day. All rates given below are effective annual rates.



Question 131  APR, effective rate

Calculate the effective annual rates of the following three APR's:

  • A credit card offering an interest rate of 18% pa, compounding monthly.
  • A bond offering a yield of 6% pa, compounding semi-annually.
  • An annual dividend-paying stock offering a return of 10% pa compounding annually.

All answers are given in the same order:

Question 282  expected and historical returns, income and capital returns

You're the boss of an investment bank's equities research team. Your five analysts are each trying to find the expected total return over the next year of shares in a mining company. The mining firm:

  • Is regarded as a mature company since it's quite stable in size and was floated around 30 years ago. It is not a high-growth company;
  • Share price is very sensitive to changes in the price of the market portfolio, economic growth, the exchange rate and commodities prices. Due to this, its standard deviation of total returns is much higher than that of the market index;
  • Experienced tough times in the last 10 years due to unexpected falls in commodity prices.
  • Shares are traded in an active liquid market.
Your team of analysts present their findings, and everyone has different views. While there's no definitive true answer, whose calculation of the expected total return is the most plausible? Assume that:

  • The analysts' source data is correct and true, but their inferences might be wrong;
  • All returns and yields are given as effective annual nominal rates.



Question 307  risk, variance

Let the variance of returns for a share per month be ##\sigma_\text{monthly}^2##.

What is the formula for the variance of the share's returns per year ##(\sigma_\text{yearly}^2)##?

Assume that returns are independently and identically distributed (iid) so they have zero auto correlation, meaning that if the return was higher than average today, it does not indicate that the return tomorrow will be higher or lower than average.
