债券价格怎么算？How is a bond priced?
价格 = 各期票息的现值之和 + 到期面值的现值，用市场收益率按付息期折现。市场收益率高于票面利率时折价，低于时溢价。Price = present value of every coupon + present value of the face value, discounted at the market yield per coupon period. A yield above the coupon gives a discount; below, a premium.
久期是什么意思？What does duration mean?
麦考利久期是现金流的加权平均回收时间；修正久期 ≈ 收益率每变化 1 个百分点时价格变化的百分比。例如修正久期 7.7，收益率上升 1% 时价格约下跌 7.7%（实际跌幅略小，因为有凸性）。Macaulay duration is the weighted average time to receive the cash flows; modified duration ≈ the percentage price change for a 1-point change in yield. With 7.7, a 1-point rise means roughly a 7.7% drop (a little less in reality, because of convexity).
