Temptation is getting higher

Temptation is getting higher. Non fundamental stocks are going up. I would be cautions and will not compromise my principles of fundamental investing. It's better to pass up some good opportunities to make "easy" money rather than get addicted and losses everything at the end. I have seen it, making sizable return based on sound investing over a long period of time but losses it within 3 days when got sucked into the black hole.
