This might be a "boiler room" operation. If you answer the phone and speak with them, the original caller will ask if you are interested in a "passive return or strong compounding return." The original caller will pass you along to someone who has more authority/knowledge or .... possibly who is simply a better "closer," to reel in the "fish." They are only interested in you if you have at least $10,000 to invest in a "proprietary program" (black box software). The automated system would be "licensed to you for 18 years" and it will automatically (presumably with artificial intelligence of a sort) trade for you in the S&P 500 future indexes. They say it only makes 4 to 6 trades per month and will give you an income of $525 per month on a $10,000 investment. That would be $6,300 per year, but the annual profit figure they toss at you is that you will make about $12,800 per month. They call their company "CTI".
