The most likely outcome of the current market is volatility not a crash.
Too many people are expecting a crash.
Crashes are out of the blue events and happen when the majority of people are bullish and fully invested. This is probably going to be a slow sideways to down market until the fed decides to pump more liquidity and give the market another bump.
I think they are getting close to that now. They just need enough scared people on side to make it politically acceptable again. We are starting to see articles in the MSM to this effect.
