Answer:
He is wrong.
Step-by-step explanation:
In order to understand this, bonds are basically loans that private individual or funds give to companies, in order to help them with cash or pay debt, they are paid in certain specifications at a certain timeframe, the problem is that interest rate is fixed, so if the market interest rate goes up, the fund is losing money having invested in that company at a lower interest rate, that is why right now it sounds smart to get a longer-term bond, instead of a short term, but in reality that's cash that you will have frozen with that company and in the meantime interest rates probably would go up.
