Should the company management and majority owners choose, they can pay one or more dividends per year to stockholders.

Example: 15% financial income tax. You cash out 10000 EUR, you get taxed 15% on this.
Dollar-cost average: This sounds complicated, but it’s not. Dollar-cost averaging means investing a set amount of money at regular intervals, such as once per week or month.

Some online brokerage firms let investors set up an automated investing schedule.
