CVS Caremark (NYSE: CVS), a big competitor of both Walgreen (NYSE: WAG) and Rite Aid (NYSE: RAD), released its Q1 earnings last week. They were very good, and they reminded me that I probably need to throw a drugstore chain's stock in my core portfolio as a long-term play on the increasing health-care needs of the baby boomers (and every other demo, for that matter).

Looking through the reported growth rates, you can see that we're talking best-of-breed here. Revenues were up over 60%, and adjusted earnings per share increased over 18%, coming in at $0.55. The Caremark merger has obviously proven to be a good move. Same-store sales rose 3.9%, benefited in part by the early appearance of Easter in March.

According to earnings.com, CVS Caremark basically matched earnings expectations. That's okay, though, I don't think you can hold it against this big brand name. As of this writing, CVS is near a 52-week high. Buying at the 52-week high is always a dicey thing, but if you plan on holding for years, it wouldn't be that much of a concern. Shorter-term traders would need to wait for a pullback. But I like the first quarter results for CVS, and I think the stock is poised to do well over time. And like I said at the beginning, this really may be a stock for the core portion of an individual's investment program -- a true buy-and-hold idea.
