Three of the world's largest asset managers have lost at least $300 billion related to their U.S-based equities over the past week as volatility returned and bond yields spiked, creating a sell-off on Friday and Monday.

After swinging wildly Tuesday morning, dropping by as much as 567 points, the Dow Jones Industrial Average rose the same amount, 567 points, or 2.3%, to close at 24,912.77. A day prior, the Dow dropped 1,175 points, the largest single-day point decline ever.

The large increase of market volatility will likely contribute to further outflows from systematic strategies in the days ahead, J.P. Morgan analyst Marko Kolanovic wrote in a Feb. 5 research note.

"However, we want to point out the massive divergence between strong market fundamentals and equity price action over the past few days," said Kolanovic. "The large market decline over the past few days will likely draw fundamental investors."

Ultimately, Kolanovic said, the market sell-off presented a buying opportunity.
