Companies are sometimes able to show very rapid growth in EPS over  a few years. This often gets investors interested and they bid the stock's price up.
 
Suppose Contesco Inc. has such a record over the last three years which have been very favorable in its industry. At the same time, however, Contesco's capital has gone from 20% to 80% debt.
 
What advice would you give to someone interested in buying Contesco stock?
