According to Yahoo NWLI traded 15712 shares today which is a large figure compared to its average volume.
However, the price didn't move very much in either direction during the day.
Earlier this year I sold some of my stock but now I am a buyer again. I bought some today at $205.49 and I also had another limit order below the market which did not get filled. I think the price is simply too low relative to other stocks or fixed income returns. Technical analysts say that the volume increases before the price changes. I expect that to happen here and I am trying to increase my position materially before the price goes up a lot.
