Health Care Stocks Are Soaring; Here's How to Invest in Them

NEW YORK (TheStreet) -- Health care-related stocks such as Aetna (AET), CNO Financial (CNO) and UnitedHealth (UNH) have become momentum trades. Today I'll provide you with information on how to trade them.

Share prices have moved higher for seven of the eight health care stocks in today's "Crunching the Numbers" table (see page 2). The table contains key moving averages, and all eight stocks are above all moving averages, which is a sign of technical momentum.

All eight also have either rising or overbought 12x3x3 weekly slow stochastics, another sign of technical momentum.

The rush to enroll in Obamacare is a factor for these stocks, as open enrollment on HealthCare.gov comes to an end on March 31.

If you already own any of these companies, you can use this information to adjust positions. If you are building positions, consider adding to longs using good 'til cancelled limit orders to buy weakness to a moving average or value levels shown in the table.

If you are reducing positions to book profits, consider doing so using GTC limit orders to sell strength to a moving average or to the risky levels shown in the table.
