The chairman of Capital Market Board (SPK), Vahdettin Ertaş, said that about 87 or 88 out of every 100 investors trading at Forex are losing, and therefore the SPK will be introducing additional measures to protect small-scale investors.On the draft about extending the withholding tax for five years, markets have been waiting intensely for some time now, but Ertaş said that there is nothing for investors to worry about.On whether the new regulations will amend the procedure in practice, Ertaş said that he cannot say anything for sure until the draft is approved by Parliament, yet he added that the recent explanations indicated that practices are not to change.Replying to a question about Forex transactions, Ertaş said that the leverage ratio on these transactions are high and while it is possible to earn TL 100 ($33.80) by investing TL 1, it is also possible to lose all money invested with a 1 percent change in the prices. He warned investors who are not familiar with Forex, not to invest large sums at first, work with few intermediary firms and not to trust deceptive advertisements.He announced that the additional measures to be taken to protect small-scale investors against big losses in Forex will come into force as of Jan 1, 2016.
