While the current bull market is older than its average predecessor, there are indications that more upside is in store for equities. Help could come from rising interest rates, a scenario that is often kind to the consumer discretionary, industrial and other cyclical sectors.

“The period before the Federal Reserve raises rates is historically a great time to invest. Over the past six tightening periods since 1980, the S&P 500 has returned 23.5 percent on average in the nine months prior to the first rate increase.

Since that time, the S&P 500 is already up more than 7 percent. Currently, a number of indicators, including my favorite, the New York Stock Exchange Cumulative Advance/Decline Line, show that the stock market is improving and can sustain its upward momentum,” said Guggenheim Global Investments Chief Investment Officer Scott Minerd in a note.
