The S&P may be creating a bearish ‘evening star' with today's loss following from Friday's doji. The index finished at its 20-day MA, although this hasn't provided much support in past tests this year. Further losses are likely.  First look for a test of 2,009, with follow through down to Fib levels.
 

The Russell 2000 suffered the largest loss of the day. This may morph into a bearish head-and-shoulder pattern, but for this to confirm a close below 1,155 is required.
