Concerns over the European debt crisis have returned to the financial headlines and are once again worrying traders. SPX lost $12 to close at $1367 and RUT closed at $792, down $12. But trading volume dropped off to 2.8 billion shares of the S&P 500. Trading on the NYSE dropped 20% and volume dropped 7% on NASDAQ. SPX is holding the support line around $1360 that was established April 10-11. SPX dropped as low as $1359 this morning, but slowly recovered from there all day. RUT behaved similarly, dropping to $785 this morning (the low of April 10 and March 6) before rebounding a bit to close at $792. The absence of any economic data didn't help push the market either way.

VIX popped up over 20% this morning, but calmed as the day wore on to close at 19%. The fact that SPX has repeatedly held the support at $1360 is reassuring. If that support level fails, watch for $1340; if $1340 breaks, then a full blown correction is underway and it could get ugly. Another reassuring data point today was the drop off in trading volume as the major indexes dropped significantly. A big down day on increasing volume would be a bad sign.

My May iron condor on RUT stands at a P/L of -$180 with position delta = +$53 and theta = +$72. The put spreads are still over one standard deviation OTM, so this position is in reasonable shape at this point with 24 days to go.
