Kommaditgesellschaft is the direct swiss/german equivalent of anglosaxon limited partnerships. Be careful with what you wish for however, in such a partnership the general partner (you) has unlimited personal liability
AG or GmbH. The big disadvantage is that they have a legal personality (that’s a plus but:) and you’d suddenly start owing corporate taxes on all profits and capital gains and when you pay dividends out, the investors get double taxed on them too, so that’s why they’re rather unpopular as a vehicle to invest some wealth
For institutional investors, yes

Before you go all crazy and gamble other people’s money, have you even tried to beat the market yourself and survived different market conditions? It’s not 1960’s anymore. Investment landscape is vastly different and much more competitive. Most people are better off just sticking to the indexes. That’s what Buffet’s saying these days too. Don’t be stuck in the 1960’s and read some of his modern pieces.
