"Until investors get an idea of how this could play out, we'll continue to be volatile," Malone said.

Hedge fund woes
Low interest rates globally over the past 5 years has allowed an unprecedented surge financial liquidity, which central banks the world over are still busy mopping up by lifting interest rates.
Fast-money investors, such as hedge funds, have heavily borrowed money at low rates to invest in higher yielding assets. Private equity funds have also borrowed heavily to buy out publicly-traded companies, fueling overall gains in the stock market.
But with rising rates, there are now concerns that the party may soon be over, according to Cowen's Malone.
"It's no secret that there's been a lot of leverage," Malone said. "But if investors begin to unwind their trades to reduce their leverage, that could have a big impact on markets."
