Stock rally could pause soon: Yardeni

While stocks are maintaining a bullish trend, a few near-term factors might be reason for a pause, Ed Yardeni of Yardeni Research said Wednesday.

The Federal Open Market Committee meeting on Sept. 18 would be the first speed bump for the stock rally, which is when it would "possibly" discuss the end of quantitative easing, he said. "That will certainly be a date to be reckoned with."

That event would be followed by sequestration, or automatic federal budget cuts, in October.

"We forget that these sequesters now will happen every year for a 10-year period, and they add up," he said. "There will also be a debt-limit fracas down in Washington, I'm sure. And then Obamacare hits us in October."

On CNBC's "Fast Money," Yardeni noted that the bullish trend was so far intact because the Fed has signaled that it would keep short-term interest rates "near zero for a very long time."

Yardeni also said that in the longer-term, stocks would continue to trend upward.

"We've had three major corrections in this bull market. 'Go away in May and come back in October' just didn't work out," he said. "Sometimes you have to know to come back in July. Sometimes you have to know to go away in April.

"I think this bull market's going to carry us for a couple more years, quite honestly. If that's the case, I think you just stay with it."

Yardeni added that "some consolidation would be overdue."

Another factor, he also said, was the amount of cash in play.

"When you add up the amount of cash that S&P 500 companies have plowed back into the market through dividends and buybacks, it adds up to a staggering $2 trillion," Yardeni said. "It's probably more than that now, and that's really what's been driving this bull market. I think you are going to see some buying by individual investors and foreign investors, but it's that cash flow that's driving the market. I think it continues."
