Analysis of the Top 10 Components of Health Care SPDR

Looking at the overvalued and undervalued data, only three of the 10 stocks are undervalued: Johnson & Johnson by just 1%, United Healthcare ( UNH) by 17% and Express Scripts by 12%, though these numbers do not take into account the after-hours pop in its share price on Tuesday.

All 10 of the medical sector stocks in the table are rated buy or better, according to ValuEngine, with UNH a strong buy.

All 10 have traded higher over the past 12 months by 13% to 58.1%, led by Amgen ( AMGN), up 58.1%, and Gilead Sciences ( GILD), up 52.4%, because the biotech companies are likely to have the more robust new drug pipelines. And they are all projected to be higher 12 months from now by 6.2% to 13.4%, with reasonable price-to-earnings ratios between 10.6 and 17.5 times forward 12-month EPS estimates.

The author advocates the use of GTC Limit Orders to add to long positions or become less short on share price weakness to the Value Levels. Traders should enter GTC Limit Orders to reduce the long positions or to add to a short position on strength to Risky Levels.

At the time of publication, the author had no positions in the stocks mentioned and no other conflicts.
