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: Shares of HMS Holdings (Nasdaq: HMSY) fell more than 15% in early trading after the company reported decent Q3 results but reduced its fourth-quarter revenue outlook.

So what: Third-quarter revenue climbed 15% to $92.4 million as profit improved 31% to $0.17. Analysts were calling for $0.16 in earnings on $96.76 million in revenue, Bloomberg reports.

Now what: Color me surprised. If anything, given all the back-and-forth over health-care legislation, you'd think HMS services for cutting costs and waste from government and private health-care plans would be in high demand. Apparently that's not the case. Do you agree? Would you buy shares at current prices? Please weigh in using the comments box below.
