who cares about a percentage gain - I care about dollars baby real dollars! 50% gain only translates to only about $12 based on yesterady's volume. That's assuming you were the only one making the trade.
And Grifco is back down 50% on $3.60 worth of trade LOL.
What does the chart say now? I see a commode-bottom-wipe & flush formation. Watch out for the skid marks and don't eat yellow snow. Of course I haven't pulled out the 50 indicators to confirm the action. However, the RSI indicates Grifco is DOA and the B.S. indicator is off the chart.
