Question:
Can I invest in a stock fund on Thursday night when the trading would go into shabbos
Answer:
Hello,
Yes, you may invest in a stock fund, even though the value of the stock will go up on Shabbos. The stock that you own doesn’t do any “work” for you, even though this is the advertising term used, that “your money is hard at work for you”. the money merely increases in value because of the rule of supply and demand, but no action is being done, therefore it is permitted.
Best wishes
