Over the past week on TheStreet, our colleagues have been talking about tech titans for earnings season, retail stocks poised to make the grade and more. Here are some of the highlights. 11 Famous Health Care Stocks to Sell: According to Louis Navellier of InvestorPlace, the health care industry, often thought to be low-risk, "has seen a big shakeup in the wake of Obama's health care reform bill and not all stocks in this sector are adapting well." He recommended immediatly selling any of the 11 stocks in this portfolio, including Becton Dickinson ( BDX), which has "failed to impress so far this year," and Pfizer ( PFE), which "has been sloping downward and the momentum might be too great to stop." The 11 Famous Health Care Stocks to Sell portfolio also includes St. Jude ( STJ) and Sanofi-Aventis ( SNY). 6 Media Stocks to Watch: Andrea Tse recommended keeping these top media names on your radar ahead of their earnings warning that the diversity of the media and entertainment sector "can also make it a minefield for investors who are looking to predict its coming hits." For example, keep an eye on Lions Gate Entertainment ( LGF), which has received attention in 2010 as activist investor Carl Icahn has raised his stake in the company in attempt to take it over. The 6 Media Stocks to Watch portfolio also includes News Corp. ( NWSA). 4 Retail Stocks Poised to Make the Grade: According to Jeanine Poggi, expectations for the back-to-school season are high, but "it's best to resist the bullish hype." The numbers retailers reported in the fall were some of the worst on record, there's really "no place to go but up." Among the four retailers Poggi predicted most likely to "make the grade" was Aeropostale ( ARO), which has "evolved from a fashion follower into a fashion leader." The 4 Retail Stocks Poised to Make the Grade portfolio also includes Urban Outfitters ( URBN).
