Midday Movers

Here is a partial list of today's high-volume movers:

• High-volume advancers: ISRG, GRMN, CHRW, FCL, LOGI, ASPM, IPS, HSC, CRI, HANS

• High-Volume decliners: PFCB, INSP, TRMB, YCC, ZBRA, FULT, WBSN, MDRX, BYD, PNE
  

Market Comments: The market is again acting resilient, holding strong each time it dips into negative territory. The market doesn't have to go down to work off its overbought condition. It can also just meander around, chopping and flopping, which would also have the desired effect.

But there are plenty of individual issues that have gotten slammed due to earnings (PFCB, ZBRA). So be careful, and make sure you know when your holdings are reporting.
