Crude, Where's My Support Car?

Some gnarly crude oil weakness (USO daily, below) appears to have finally stressed out the senior indices a bit today, even as QQQ is still green as I write this into the bell.

The small cap ETF also sliced its 50-day moving average, which saw me lightening up long inventory. 

Overall, while it is not across-the-board bearish action, it is certainly worthy of a yellow flag to slow me down. 

More in my recap after the bell.
