Why buy stock of a company instead of the holding company who has more than 99% of the stocks
Also VW has more brands, i.e. is more diversified This isn't necessarily a good thing for investing.  It makes the company less likely to go down, but it limits your portfolio.  For example, say you think that Hyundai is a good alternative to Volkswagen (VW) but really like Audi.  If you buy VW, you get some Audi but a lot more of the rest of VW.  Then if you bought Hyundai, you'd be overrepresented in that segment of the market.   Audi may not be structured uniquely, but it is still the only company selling Audi brand cars.  Perhaps someone thinks that those models will do well.  That person may think that Audi will do exceptionally well in its niche.   Having many brands isn't necessarily great.  General Motors had something like sixteen brands before declaring bankruptcy.  It only has twelve now.   Now, it sounds like you feel the opposite about it.  You don't particularly like Audi as a stock and like VW better.  Your reasons sound perfectly reasonable (I know little about either company).  It may even be that VW is the only one buying Audi stock, because everyone else has the same view as you.
