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 Volterra Semiconductor (Nasdaq: VLTR) fell 10% today on concerns about a product delay.

So what: Inphi (NYSE: IPHI) cut its outlook yesterday on concerns that Intel's (Nasdaq: INTC) Romley chip for servers would be delayed. This affects Volterra because the company makes voltage regulation chips, which should see a boost in demand because of Romley when it is released.

Now what: This delay may have a short-term effect on Volterra’s results, but after soundly beating earnings estimates in the second quarter, I’m not too worried. Romley hasn’t been canceled and should still have a positive impact on results in the future. I think this sell-off is overdone for Volterra, and it presents a nice buying opportunity in a company that is expected to grow earnings quickly over the next year.
