According to what I've been reading, bond prices fluctuate based on what interest rates are. I was thinking of maybe buying Wal-Mart bonds which are currently priced at $115.30 with a 5.80 Semi-annual coupon. The maturity date is February 2018. I'm new to bonds. I want to understand how much that bond price will fluctuate between now and February 2018. Thanks a lot for your help.
