I can reply based on my reasons to buy stocks: brazilian Central Bank went on proceeding with savage cuts on interest rates, following the USA Central Bank. So conservatives investments, until 2015 counting on 15% of interests, making savings the best favourite brazilian investments, are now generating crumbs, very low than the current inflation. One of the ways to not lose money due to inflation is stock investments. Well, I talked about losing money due to the current conservative investments: the reality it not exactly losing money literally, but devaluation, depreciation. This is the reason this year I began to invest in stocks. In any way, I had a good training about commerce, business, dividends and economy during my first degree, so it's not complicated for me to rekindle these subjects and deepen knowledge. This doesn't mean knowledge set us completely out of risks (remembering each investment owns a percentage of risk -no risk investments simply don't exist- and stocks own high risk rate), but helps. I advice to study the subjects related to stocks, remembering we also need to invest based to our country reality. I invest based on latin american reality.
