Just finished watching Wolf of Wall Street, eh?
Sure, there's an inherent risk with investing...NO ONE can predict what will happen tomorrow, next week, next month, ad infinitum. However, by investing in companies with solid fundamentals, good leadership, good projected growth, a great service/product, etc, you can mitigate some of that risk. I don't think anyone is advocating putting your nest egg in Herbalife. But owning a small amount of HLF along with a balanced, conservative portfolio is not a terrible thing...diversification is key, and it doesn't just include stocks/bonds.
