New Shareholder here Just got in last week and what a move! No need to speculate on if's or and's, the chart tells the story.. new all time highs on increasing volume! What more can you ask for!
SIS is a hold above $4.90 in my opinion long term, the 50 day moving average is rising and ready to catch up and the 21 day MA at $5.05 should provide near term support.
