Oh, mine! I've JOMOed a lot if I looked at it now, both in trades and investments. It's a great feeling to have if one had once experienced it. I'm cocksure every active trader and investor would've encountered such moments where they were extremely happy they stayed off a trade or investment that later went sour. Nothing beats that happiness and chest beating with a knowing smile that one was sagacious enough to have listened to an inner voice.
i mean when you buy because for you it's the right time of course there's a joy and fear at the same time. Lol
If you experience fear after buying in, it's called doubt. Fear before buying in is quite understandable but fear after buying in isn't a good sign.
