Stocks are tumbling on the first trading day of 2016, with the Dow down more than 300-points.
"Volatility levels [are] likely to be higher next year as Fed unwinds," Tanious said.
He expects 2-4 rate hikes this year and believes the Fed removed some of the market uncertainty by raising rates in December.
"Earnings [are] likely to reaccelerate into 2016 as the drag of lower oil prices begins to fade… We still believe mid-single digit returns are achievable in equities," Tanious said.
The Dow, S&P 500 and Nasdaq are all lower during trading.
