Sam Stovall, a veteran Wall Street strategist known for his study of market patterns, sat down with CNBC's Mike Santoli for an in-depth interview on the various principles he uses to predict market returns and evaluate stocks.
Stovall explains why he believes the should be trading at around 2,340, or only about 2 percent higher from here.
"The reason we haven't stumbled with a P/E so high at this point is, we've had inflation in the low 2 percent area. So as a result, we can stand higher valuations when inflation itself is lower," he said.
In this exclusive conversation, Stovall, who first joined Standard & Poor's in 1989 and now serves as chief investment strategist at CFRA, defends his market-timing methods against the passive investing onslaught.
"The reason why history works is because one element has been consistent throughout the beginning of time and that is human reaction," Stovall said.
