The yield on the 30-year U.S. bond rose to 3.215% on Dec. 12, two days before the Federal Reserve Open Market Committee raised rates. My value levels are 3.271% and 3.296%. This yield could rise slightly above 4% in 2017, but a significant rise in yields is not in the cards.

Comex gold futures traded as low as $1,124.3 the Troy ounce on Dec. 15. This week's value level is $1,089.16. Gold could trade as low as $805 in the first half of 2017, but could also trade as high as $1,633 during 2017.

The Dow utility average bottomed at 616.19 on Nov. 14, then rebounded to as high as 665.93 on Dec. 14 as the FOMC raised rates. Investors will always be seeking the safety of dividends, and this average should rebound to 700 at some point in the first quarter of 2017.
