Option 最容易赚钱的策略就是赚取 time decay. 你正好想反了。time decay 应该当 成朋友,而不是敌人。你可以先试一下卖指数的 put, 比buy and hold 风险小,风险 主要来自于 leverage, 因为option很容易用上leverage。
兄弟,送你一首诺贝尔民谣歌手的歌吧: How many roads must a man walk down Before you call him a man? How many seas must a white dove sail Before she sleeps in the sand? Yes, and how many times must the cannon balls fly Before they're forever banned? The answer, my friend, is blowin' in the wind The answer is blowin' in the wind
