Sellers were able to put some distance on resistance which gives shorts something to work with. The S&P closed just below 2093 support, but above 20-day MA; a loss of the latter opens up support at the 50-day MA, then the swing low at 2040.

The Nasdaq undercut psychological support of 5000, but not far enough to suggest it has returned as resistance. The false break of 5000 ranks as a 'bull trap'.

The Russell 2000 didn't experience big losses, instead it finished with a second doji near Friday's highs. Action in this index remains positive despite selling in other indices.

For tomorrow, bulls can keep an eye on the Russell 2000, and bears on the S&P / Dow Jones Industrial Average.
