65. Interest rates and bond prices

We will be talking about it on Tuesday. Here is an article that says just that: if interest rates rise, bond prices fall.
Bond ETF (Exchange Traded Funds) are saving instruments sold to general public which follow bond prices. With interest rates at historical low, interest rates are likely to go up and bond ETF prices to go down.
The article mentions a simple calculation of bond losses from increase in interest rates. It is that, for a 1% increase in the interest rate, the price of bond will lose n% where n is the number of years to maturity.
This calculation is not quite correct; you will learn the detailed formula in your finance class.
