I have more than once bought straddles and profited from this. More than a double on August’s earnings. Even if it opens flat you can get out with a small loss or breakeven. However, I’m seeing today’s straddle is going for about 6.00, which is over a dollar more than I paid in August. I’ll be considering it at day’s end.
