NEW YORK (TheStreet) -- U.S. markets continue to climb, with the S&P 500 Index setting and breaking all-time highs multiple times over the past two weeks.

Tim Hockey, President of TD Ameritrade (AMTD) - Get Report and successor to CEO Fred Tomczyk, has seen an increase in the number of investors joining the stock market.

"We see our new account openings up year over year," Hockey said on CNBC's "Closing Bell" Tuesday. "Cash levels are actually declining at all-time, almost all-time lows in terms of a percentage of their holdings."

After the U.K. referendum to exit the European Union caused a drop in global markets, Hockey says there was "a little bit more investment back in the markets as a result of the opportunities that afforded them."

Passive investing is on a steady rise while active investing is holding steady, according to Hockey. Long-term investors are shifting from "traditional mutual funds to ETFs," but active traders are still looking for "opportunities to take advantage of those market disruptions like we saw with Brexit," Hockey noted.

Shares TD Ameritrade are down by 0.2% to $29.87 in after hours trading today.

Separately, TheStreet Ratings Team rates TD Ameritrade as a "buy" with a ratings score of B. 

This is driven by multiple strengths, which TheStreet Ratings believes should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks TheStreet Ratings covers. The company's strengths can be seen in multiple areas, such as its revenue growth, notable return on equity, expanding profit margins, good cash flow from operations and growth in earnings per share. TheStreet ratings feels its strengths outweigh the fact that the company has had lackluster performance in the stock itself.

TheStreet Ratings objectively rated this stock according to its "risk-adjusted" total return prospect over a 12-month investment horizon. Not based on the news in any given day, the rating may differ from Jim Cramer's view or that of this articles's author.
