's Shares Got Crushed: What You Need to Know

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 online genealogy (NAS: ACOM) hit a dead end today, falling as much as 11% on very heavy volume.

So what: Analyst firm Wedge Partners just lowered its earnings outlook on Ancestry because a recent change to subscription pricing probably wasn't factored into management guidance. After Wedge published its worries, Bank of America chimed in by calling the concerns "overdone."

Now what: Raising short-term fees while offering long-term discounts looks like an attempt to lock customers into longer-term commitments, and Wedge worries about sticker shock on those longer contracts. These changes can cut both ways: Detractors see Netflix (NAS: NFLX) taking a huge hit to subscriber counts from its recent rejiggering while Sirius XM (NAS: SIRI) enthusiasts see nothing but dollar signs in a long-delayed rate increase. Maybe I'm naive, but I'd like to think that Ancestry's leadership has done the math and arrived at a generally positive outcome from these changes. Then again, I also believe that Netflix will do all right.

The proof is in the pudding: Add toMy Watchlist.
