Reply To: jury duty or "just following orders"

Joseph, that is a big discussion about which much ink has been spilled. If you want to be machmir you cannot own shares in any corporation that operate on Shabbat or pays or receives interest. If you own shares in a corporation that owns chametz you must include them in your pre-Pesach sale. Non-kosher food is also a problem as one may not conduct business with them on a regular basis. Meat cooked in milk is completely out. If you want to be really machmir you will not invest in a pension fund or insurance policy where the fund invests in such companies.
