Sorry about the late post, I had internet problems all day. HK was last week's biggest gainer, and last week gave us a nice bounce off the 200dma. Last week's move up had high volume, and relative strength is high. Energy stocks seem to be among the few that did well last week.
JST was the second biggest gainer and seems to be stuck in a trading range here. There is nothing really compelling about this chart.
WFR was the biggest decliner. It actually did not look bad as of last Thursday's close, but got absolutely crushed on high volume last week. It might get support at the 200dma, but I wouldn't count on it.
