證券投資風險性排列

這裏隻講投資，期權期貨等投機產品不在範圍中。證券投資按風險從大到小的排列是

1. Common stock - 股價波動大，風險高。

2. Common stock dividend - 當公司經營變壞，現金緊張時，會最先 cut common stock dividend

3. Preferred stock and its' dividend: 當公司經營更差時瀕臨破產時會停止支付 preferred stock dividend, Preferred stock price will eventually go worthless.

4. Corp Bond: 公司破產時會停止支付利息， bond price will decrease significantly. 但是在破產清算時， bond holder had priortity over preferrred stock holder. Bond holder may get something back from their investment.

5. 國債，違約可能極小，但也看那個國家，阿根廷國債曾多次違約，但投資人拿回的錢比公司債多。

6. Certificate deposit， FDIC insured up to $250,000 per account. 基本無風險。
