There is major support around 292.60 for SPY the S&P ETF and this level will be tested today.
The Nikkei has broken its Major Support
I see some evidence in market sentiment indicators that extreme levels of pessimism have quickly been reached, these normally associated with market lows. For example, there has been a huge net outflow of 22.1 Billion dollars this week from U.S. mutual funds. A net outflow of more than 20 Billion dollars in a single week happens rarely, but when it does it usually indicates a market low of some degree is close.
I also note that the CNN Fear & Greed Index is now registering Extreme Fear, where one week ago is was Neutral.
Considering the huge sell-off in the S&P 500 this week, the decline in the Rydex ratio is not yet registering panic/fear, which suggests there may be more downside first.
