Not long ago, I wrote about Netflix (NFLX) hitting a 52-week high. At that time, the shares were around the $75 level. I cautioned that one had to be careful about buying an overbought stock. I mean, how much further could the equity climb?

Yeah, right. At the close of trading on Wednesday, the shares were priced at $86.98. The current 52-week high stands at $89.10 (as of this writing). And during yesterday's after-hours session, the stock climbed 1.6% to $88.40, in response to the first-quarter earnings report.

Blockbuster (NYSE: BBI) remains troubled. Just look at the second-quarter report that was released on Thursday after the bell. Net sales dropped over 20%, coming in at roughly $1 billion. The company lost 19 cents per share, one penny better than the loss reported in the year-ago period (to which I say, big deal!). According to the preview, the market wanted to see $1.1 billion for the top line and a loss of only 12 cents for the bottom line. A failure on both counts, I'm afraid.

Cash flow was the more attractive part of the Q2 story. The company calculated its free cash flow to be about $109 million. Okay, I'll give Blockbuster a good mark for having positive cash flow this year.
