Ex Input:
I heard a short segment on Stu Epperson's radio show as he discussed investments with Steven Selengut. I heard enough to prompt me to search for his book on the internet. As a securities rep. myself, Steve appears to be "right on the money". I didn't want to put the book down until I was through. Steve's trading strategy is refreshing information that should make a lot of people a lot of money with less risk. I have even contacted him with a couple of questions and was pleased with his prompt and courteous response. Thank you Steve for sharing your success with everyone. In your next book, please remember that all "advisors" are not "sharks", some of us do put our clients first.
