May a Christian speculate in the stock market or in Internet stocks?
A Christian can speculate in the stock market or in Internet stocks, as long as he does so within the parameters of normal business practices for prudently investing one’s own or someone else’s money and does not thereby break any other commandments. Speculating in stocks becomes immoral when dishonest means are used (for instance, insider information); when the transaction puts one’s own or another’s life savings at risk instead of insuring an income; when such speculation becomes an addiction, as with games of chance.

May a Christian make bets and play games of chance?
Betting and gambling are immoral and dangerous when the gambler risks his livelihood. It becomes even worse if he risks the livelihood of other people, especially of those who are entrusted to his care. Morally speaking, it is a highly dubious practice to wager large sums on a game of chance while others lack the bare necessities of life. Betting and gambling, furthermore, can be addictive and enslave people.
