That massive sell off obviously involved a certain amount of market manipulation by some very big whales in the trading pond.
If the whales are satisfied, I expect the slow movement towards previous levels to continue. On the other hand, if that was just the opening course of their meal, this pullback could just be them waiting for more small investors to get in and place easily breached stops before another shove downward. Considering how many people are nervous after what happened, it wouldn't take too big of a push to trigger a wave of panic selling.
