Are shares a safe investment?

His is a question that can hardly be answered in a generalized way. An investment in shares that seems safe for one person can mean completely unsafe for another. But what factors determine whether a stock can be considered a safe investment? In principle, there is no absolute certainty, and the future is uncertain. We all know that! Nevertheless, things can be steered to a certain degree with common sense and clever calculation, even for the future. This also applies to investments, which we can control ourselves and make successful with a few basic rules. This also applies to an investment in shares. With a share, one participates in the equity of a company and becomes a co-owner of the company. If the shareholding is to be as secure as possible, then it is crucial that the company survives and does not go bankrupt. Moreover, it would be even better than just safe if the company can increase sales and profits in the future. If this is true, then its shares will also be "safe". Now the big question is: Which companies are these? These are companies that pursue outstanding business models. Business models that are unique and cannot simply be copied. Business models with high market entry barriers for competitors. A company that is very well positioned in this way has pricing power and can achieve high margins in its business. Classic examples of such companies are Google, Microsoft and Apple. All three companies that have dominated the market in their sectors for years or decades and have grown almost magically. And, of course, have given their owners, i.e. shareholders, much pleasure. Now, however, the task is not to identify these companies after the fact, but in advance.
