"Usually when people plan to invest, they only think about profit and they don't think that loss's possible", says Harold Evensky, the President of the financial management company Evensky & Katz. He said that sometimes people do not do basic mathematical calculations.
For example, forgetting that if in one year they lost 50%, and the following year they received 50% of the profits, they did not return to the starting point, and lost 25% savings. Therefore, think about the consequences. Get ready to any options. And of course, it would be wiser to invest in several different investment objects.
