I don’t know why Jane’s so cranky — Wall Street’s happy.

The stock market’s collective view seems to be that health-care providers will indeed profit, or at least, that they will suffer less than originally believed. Since the end of October, the broad U.S. stock market has gained 8%, judging by the S&P 500 index. Exchange-traded funds that track segments of the health-care sector have done better. The iShares Dow Jones U.S. Medical Devices Index Fund (IHI: 52.55, +0.59, +1.13%) is up 10%. Sibling funds that track drug makers (IHE: 57.73, +0.84, +1.47%) and health-care insurers and providers (IHF: 49.33, +1.12, +2.32%) are up 13% and 18%.

Mission accomplished.
