Some conservative investors might cringe when they hear the term "junk bonds." Investors with a higher appetite for risk may start to smile, looking forward to those fat juicy yields way above what they can earn in most dividend stocks or Treasury yields. With 2016 coming to a close, and with the presidential election making most of the public neurotic, investors need to consider several things about yields in general — particularly in junk bonds.

The quality of stock dividend hikes will matter more and more as 2017 gets closer. When investors decide whether to chase high-yield bonds or go for stocks, they will focus on stocks that have raised dividends for many years, and ones that can keep raising their dividends for years. 24/7 Wall St. listed four Dow stocks that have and that can continue in the years ahead. Through time, these can create serious rivalries for junk bond investors — and you are not likely to see any threats of defaults in players like that.

Please know what you own. It has just come back into the light that even .

As always, caveat emptor!
