Diamonds and Dogs

10/15/15

Today's diamond keeps your blood sugar level low while the stock moves higher.  DexCom (DXCM) jumped 19% today thanks to strong third quarter earnings with sales up 52% to $105 million year over year. Biotechs have taken it on the chin recently, but not DexCom. DexCom's products have been in strong demand helping monitor glucose levels in both diabetic and non-diabetic people. After today's rally the stock is up 50% year to date. Not bad in a market that's flat for the year.

Binge watching Netflix shows like House of Cards didn't help the stock today. Netflix (NFLX) dropped over 8% following disappointing earnings and sales. Netflix is still extremely popular among subscribers, but with a high valuation, the company needs to keep building on its growth. For example, third quarter subscribers were impressive at 880,000, but compared to last year's third quarter of 980,000, it wasn't up to Netflix standards.  The company blamed part of the slower growth on customers switching to chip-based credit cards with new card numbers. Sounds kind a like the dog eat your homework. The good news is Netflix's expansion plans overseas should boost subscribers going forward even as domestic growth slows.
