It's a matter of faith. Investors are being asked to be patient.

Blue Nile has a great opportunity. It has created an attractive little niche in the jewelry industry and it should continue to grow so the valuation for the longer term is fairly attractive.

It's just a combination of a good solid quarter and some pretty solid guidance going forward.

These are strong results for Amazon. That's for sure. After some mild disappointments in the past that wasn't the case this time around.

Amazon looked pretty strong on sales although gross margins and operating expense were somewhat lower than expected.

These were pretty decent numbers overall. There was some concern over the sales numbers, but revenue also was strong for the quarter. There doesn't appear to be any letdowns here.
