Anyone else notice the big whack of volume at close last night on the NAS. Around 800k on the close and one parcel of 257k shares. A bit of volume in the after hours too. Tax loss selling perhaps? I'm sure there will be no shortage of buyers ready for those selling before tax time. I have a feeling some shorts have been waiting for this point to cover as many as they can, and think we might see things start to creep up in the new FY once the selling is out the way (and the revenue is due to start flowing).

Have a good weekend all.
