What to know about your portfolio: S&P earnings are down, which suggests the large-cap index may fall further. In the meantime, bonds, which have been in a bear market for decades, are flashing much higher yields than a year ago – that’s good news for investors. But you need to think about reallocating, because what worked for the past 10 to 15 years won’t work, going forward. You can no longer just “buy and hold” and hope for the best.
