Another year is nearly in the books, and U.S. stocks, as measured by the S&P 500, are poised to post their fifth consecutive calendar year of gains. Depending on how December concludes, it may even end up being the best calendar year in over a decade. Through the first eleven months of the year, the index is up a stellar 29%. The question many ask is, "Can stocks continue their run, or is the equity bull market getting long in the tooth?" In our opinion, the answer to both parts of the question is likely, "Yes."
