所以呢， Option是股市中有用的工具（否则它为什么可以一直存在，还变化无穷），用来避险，并不会增加额外风险， 避险做好了，盈利就会出现 – 时间，场合，对象。。。
“Options are another asset class, and when used correctly, they offer many advantages that trading stocks and ETFs alone cannot“.
“ Options are powerful because they can enhance an individual’s portfolio. They do this through added income, protection, and even leverage. Depending on the situation, there is usually an option scenario appropriate for an investor’s goal. A popular example would be using options as an effective hedge against a declining stock market to limit downside losses. Options can also be used to generate recurring income. Additionally, they are often used for speculative purposes such as wagering on the direction of a stock“
“ Options traders can profit by being an option buyer or an option writer. Options allow for potential profit during both volatile times, and when the market is quiet or less volatile.“
Option好处之一还有：完全不必分牛市熊市，同样可以操作，不需要等到牛市才装神作仙
