In my opinion, this low volume is to be expected given the lack of news as a result of the SEC quiet period. For the most part, those that wanted shares based on recent news have already done so, and those holding shares aren't willing to sell at current prices, meaning we expect it to go up. There is a relatively small number of people who may buy/sell for trading purposes or who find a little more cash on hand than they were expecting, or need to make an emergency sale, but I agree with VP 100% that most shares are in strong hands where it pertains to individual investors.
I don't believe that todays low volume is anything to worry about and for me, thinking of buying a little more during this temporary lull.
