Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Do you ever experience deja vu? I almost feel like we've done this before -- maybe 24 hours ago? Just one day after reporting better-than-expected second-quarter results and jumping more than 25% at one point, hospital and outpatient rehabilitation clinic operator Select Medical Holdings (NYSE: SEM) is diving as much as 23% after receiving multiple analyst downgrades.

So what: Count them out: Not one, two, or three, but four separate Wall Street downgrades today have Select Medical spiraling downward. Bank of America Merrill Lynch, UBS, Baird Equity, and RBC Capital Markets all lowered their ratings on Select Medical, citing little upside in the stock after yesterday's move. In particular, the covering analyst at Merrill Lynch noted the potential for rising costs in the face of uncertain reimbursements for long-term Medicare-dependent providers over the coming months.

Now what: What I said yesterday, I will repeat today: I love staying on the sidelines! Personally, I saw less risk for analyst downgrades than for credit rating downgrades from the top ratings agencies. Either way, things aren't going to be a cakewalk for Select Medical. I feel its future still remains bright, given the enacting of Obamacare in 2014, which will secure much of its revenue stream, but it could face multiple headwinds leading up to that date.
