Quote from Lawrence Chan:
The low volume problem persisted today. So definitely not a new year week problem.
Remember the bear market years 2001 - 2002?
Volume on stocks goes to almost nothing causing multiple market making firms to belly up.
Not sure if it is a sign that people are moving away from stocks and indices as mentioned here by B1S2.
Edit: Another possibility - almost everyone who has an opinion to long/short overnight had already done so.
"It was the kind of market in which not even a skunk could make a scent."
