$Amazon(AMZN.US) options have been worn out for more than a month, and I can only sell them to stop the loss. I bought them before the earnings report was released, made 3 to 4 times the profit, but due to my own greed, I didn't sell them and failed to take profits properly, turning what was originally a big gain into a loss. Fortunately, I strictly controlled the position size, but it still turned from a profit of 15k to a loss of several thousand. No matter how bullish you are on a stock, you still need to be cautious when buying options and must set proper profit-taking and stop-loss points. The underlying stock can still be held, and I remain bullish. The market is currently dominated by volatility, so I won't trade any options.
