Stocks were headed for a correction regardless of geopolitical risk, Josh Brown of Fusion Analytics said Tuesday.
"That gorgeous 50-day moving average, which had been in an uptrend pretty much all year, is now flattening out, decliners versus advancers," he said. "That is a disturbing trend you don't want to see. And so I think what you're looking at right now is a continuation of this correction."
On CNBC's "Fast Money," Brown said that a down market wasn't cause for concern yet.
"It's perfectly healthy. There's nothing wrong with it," he said. "If people want to point to Syria today, they want to point to the debt-ceiling debate next week, whatever they need to do to explain this to themselves, but frankly the market had been tired. Earnings season has passed us. There were no other catalysts for a leg higher. So, right now we're in pause and you're seeing some of the safety assets take the reins."
