The markets were mixed at the end of the trading day on Friday, November 28 on light volumes post the Thanksgiving Day holiday. Oil was lower at about $67 a barrel post the OPEC decision to stay put on production targets. This led oil stocks lower, with shares of ConocoPhillips, Exxon Mobil and Chevron under pressure. Airline stocks on the other hand headed higher. Today is Black Friday, so of course, the focus is on the retail sector. Walmart and Target released figures as both were open Thanksgiving Day. The clear winner was sales made on the web, with Target nearing its 2013 Cyber Monday record with its online take. Bad news at Best Buy as its website was taken down Friday morning by a glut of mobile traffic. It's troubling at a time when the market for buying electronics and gadgets is so competitive. The site was back up by noon.
