Most folk complicate buying shares.
If you just want a nice comfortable retirement and not expecting to become rich in six months:
1. Start as soon as possible
2. Don't sell, just buy every month
3. Spread across different industries
4. Enjoy an average 10% gain boom or bust
@baltizar33@konstructivizm Calm down. It's all to do with size and how much light it reflects. Some of these distant nebulas are light years across in size. Stars themselves produce enough light to be seen thousands of light years away. Comets are tiny things in comparison.
