SA..IMO the reason is seen on the chart...notice that it had breached the MA100...but just like a stock each support level is good until proved otherwise...It simply crossed back above the 100 as a near term show of support....chart
Who knows but it pulled CHNG to 6.92 close SA...got me smiling after it had fallen as low at 6.40 from my 6.80 first buy and added more at 6.50 on the way back up...LOL! tuna
