"my only regret is i did not buy more when siaf was below 20 nok. my avg. buying price is ca. 25 - 26 nok. is it a good idea to buy more at the current price 2.85 usd?" Nobody can answer to your question behalf of your self. You should not invest in anything more than you are willing to loose. That amount is up to you, nobody else can tell you that. Put your money in as much you want. Most in here thinks that fair price of this company/stock is more than 4X the current value. Wish you best luck!
