Down through the ages people have citied the Bible as license for every action imaginable, you are no different, just don't fool yourself into thinking you are doing God's work.
Besides, greed is good, right?
I did not site the bible as a license for stock market investing. You cited the bible as forbidding it, yet you refuse to provide the appropriate passage. So, please cite the parts of the Bible which you think forbid stock market investing - if you can.
