Hello, the question itself is very good. The historical returns on the stock markets can also come to an end. Just look at the 60s...70s, sometimes it took 30 years at the peak to get your money back... We are entering a situation with high inflation; interest rates will probably only be able to rise moderately (The means of central banks are limited without plunging entire countries and most companies in the world into the abyss) but nonetheless, we are economically entering a different situation than the last 20 years, so please do not uncritically project the returns of the past into the future!!!! For example, high raw material prices pressure the margins of the much-loved consumer goods stocks, which may eventually no longer be able to pass on their price increases and then have to struggle with declining margins. This can currently be seen nicely in most stock prices, moving sideways and downward while the indices still have record highs. Do not misunderstand, I am significantly invested in the stock market, but one should find a healthy balance and not go all in on stocks as I read here; otherwise, combined with a possibly not-so-rosy real estate market (and inflation is no guarantee that real estate will continue to rise), it could lead to a nasty awakening, although I am optimistic about debt-leveraged tangible assets. I have financed everything only for 5 or 10 years and make sure to fully utilize the special repayments on my owner-occupied house every year. Everything left then actually goes into stocks. However, years before preparing for my own house, I had already started acquiring rental properties that easily finance my own house, so that a mid-four-figure amount remains monthly as cash flow for reserves, investments, and special repayments after all living expenses. A healthy mix makes it, and an important contribution here: listen to your gut feeling... you have to feel comfortable. There is nothing worse than the real estate prices crashing by 30%, your equity in real estate being eaten up, and you can no longer repay the debt portion of your house with a sale, and we have a stock market crash... if it is down 20..30%, inexperienced stock investors are quickly pushed out of the market at the lowest point... do not underestimate the psychology of the stock market!!
