After a week off, Ebb & Flow returns to find that the biotech market still hasn't caught the coattails of the broad market surge in the fourth quarter. Since eclipsing the 6000 barrier on Oct. 14, the Dow Jones Industrials are up 6.2 percent, while the S&P 500 is up 5.1 percent and the NASDAQ Composite is up 2.5 percent over the same period. Meanwhile, even after last week's 3 percent gain, the BioCentury 100 has slipped 5 percent.
