S&P to Correct 8-10%: Mary Ann Bartels

The S&P 500 closed flat on Wednesday with investors wondering if the rally had run out of steam – or if the market had merely paused before another push higher.

Looking at fundamentals it’s possible to make the case for both a sell-off as well as a rally.

When fundamentals are conflicting as they seem to be right now, the pros often consult technical analysis for additional insights.

And few technicians understand chart patterns better than BofA Merrill Lynch analyst Mary Ann Bartels.

In a live interview on CNBC’s Fast Money, Bartels reminds us that September is often a terrible month for stocks and her proprietary research suggests this September will be no different.

“I think the market is set up to correct,” she says.

Bartels has been looking at a lot of technical signals one of which is the relationship between the Vix and the S&P. And the divergence between the two indexes is at again at a level that’s been a problem, historically. “This is where the market has sold-off in the past,” she says.

Also she says small caps and transports are not confirming advance. And she doesn't like that the market has gained on low volume.

All told, Bartels says, “I think we’re set up for 8-10% correction.”
