While a bear market seems light years away based on how the markets are performing, history tells us one eventually will occur.

Now modern technology has added a twist. With the popularity of robo-advisors for investing, the new question is how effective such tools will be when there's a downturn in the market and their human users want to let emotion into investing?

"During market highs and lows is when an individual's philosophies and established strategies are challenged," said Lou Cannataro, senior partner and wealth advisor at Cannataro Park Avenue Financial. "This is where the robo-advisor alone cannot help, remind, clarify and demonstrate how to make the correct decisions and stay on track with your long term planning. One cannot input their personal goals, greatest fears, greatest obstacles and individual circumstances into an algorithm that handles all aspects of their life and planning."

However, some see a different side to it. Yuen Yung, chief executive at Casoro Capital, said robo-advisors could actually be extremely helpful during recessions or down times.

"During a recession, the whole idea is to stick with the investment plan or strategy, and a robo-advisor can actually help because it doesn't have emotion in the equation," Yung said. "The only issue I see is if investors don't follow the strategy, as the robo-advisor can't stop the investor from doing the wrong thing."

Yung said the average investor can and should utilize robo-investing.

"If your net worth and investable assets are above $1 million, then start thinking about a human advisor," he said.
