FYI: Investors often hear that they should be buyers in periods of market weakness, but that can be psychologically difficult to do in practice. What, they wonder, if the bad news that precipitated the decline keeps on coming, or gets even worse? The ability to stay disciplined during volatile markets is one of the best rationales for holding mutual funds rather than overseeing your own basket of securities.
