Q

what is the difference between a structured product with derivatives and an insurance policy?

A
  • if you take out insurance, you will only be paid if the event occurs, and will be paying a premium until that time or the insurance is cancelled
    • Will your shareholders tolerate this?
    • What happens in the case of earthquakes –> if the damage scale is large enough the insurance company doesn’t have to meet your claim
    • you will only have one pool of counterparties
      • AIG went bankrupt when Lehman Brothers collapsed –> didn’t pay insurances claims and had to be bailed out by the government
  • The use of a derivative product to hedge the risk:
    • doesn’t completely mitigate all the damages
    • if you create this liability and sell it as a bond (CAT bonds)–> you pay periodic payments and if the event occurs you simply don’t pay back the debt
    • many investors in bonds so you can spread to risk across multiple counterparties
    • Although this is riskier so you will pay a premium on the bonds –> senior bond

Q

What is the alternative tick rule the SEC brought in Feb 2010?

A
  • Under this rule, when the price of a stock has decreased by more than 10% in one day, there are restrictions on short selling for that day and the next.
  • These restrictions are that the stock can be shorted only at a price that is higher than the best current bid price. Occasionally there are temporary bans on short selling.
  • This happened in a number of countries in 2008 because it was considered that short selling contributed to the high market volatility that was being experienced.
