The news of RTK contracts with major airlines and interest by the USAF on or about Aug. 21st and the fact that the stock continues to daily hold around $2.00/share. It's low of $1.85 does not hold very long and shoots back up to $2 bucks. RTK's planned business conferences across the U.S. in September will surely boost this stock. Not even to mention when they annouce more contracts for their exclusive Bio fuel technique. Volume is interesting for this stock. Though its price is being held back for now with short sellers. Some huge purchases have happened in the last week or two. Market Edge has RTK as a buy. Vector Vest has it as a hold.
