I wouldn't pay too much attention to price action late in the day. There was one broker determined to keep the price down when you look at the level 2. Basically the buyers were at 6.3 bidding up to 6.6 and this broker walked it down from 6.6 to 6.4 for a 6.35 mid price. They moved it to 6.45 and back and forth to 6.4 in the last hour which was well out of sync with the other broker offers but resulted in 6.375. The next offers above this establishment is 6.7 so once market "offer" of 6.45 is taken out this should be high 6s or 7s next week IMO.
