     ADAT       $0.190       17.50%       737,036         63.39%       425,617         36.61%       311,419         16,390  
     THOR       $3.350       12.21%       1,978,805       49.31%       1,947,127       48.52%       31,678          95

Analysis of the Friction Factor chart above shows that each of the six stocks mentioned above have high net buy volumes (buy volume, sell volume) and low price friction in their stocks. The Friction Factor displays how many more shares of buying than selling are required to move a stock higher by one cent or how many more shares of selling than buying moves a stock lower by 1 cent.

For example, the chart above shows SNDA with a dollar gain Monday of $7.84000 and a Friction Factor of 94 shares. That means that it only took 94 more shares of buying than selling to move SNDA higher by one penny. The Market Makers are currently allowing the stock to rise quickly (low friction). The combination of low friction and positive market direction can drive prices higher much faster than normal.
