Diversify, Especially If You Don't Know What You Are Doing! 一定要保持多样化，尤其是在你不知道自己在做什么时！ In the words of famed e conomist John Maynard Keynes, diversification is insurance against ignorance. 著名经济学家John Maynard Keynes说过多样化是战胜无知的保证。 He believed that risk could actually be reduced by holding fewer investments and getting to know them extraordinarily well. 他相信少做几种投资并且非常了解这些投资真的能降低风险。 |
