A multi-billionaire could become super rich mostly because they they have a profitable business or they invest in other people’s profitable business.  Their wealth is growing over the years, some could be as rich as the wealth of a small country.

We may not be able to establish the same business as them but we could make friends with these multi-billionaires by becoming a shareholder of their business.  Alternatively, we could also study their stock portfolio because they also invest in other businesses.

So, what are the billionaire stocks to buy?  The Billionaire Index is a compilation of stocks owned by global billionaire investors

Based on a homework done by Ein55 Graduate, many (but not all) of these stocks by billionaires are strong business. So, it it is critical for us to know what are the truly giant stocks which make these billionaires richer over the time. Even we may not become a billionaire, we could share a profit by becoming a millionaire one day, if we know their investing mindset.  More importantly, many of these stocks are at high price due to high optimism of US market.

We only make friends with these billionaires when their net worth is reduced by more than 20% one day during global financial crisis due to falling down in share prices but the strong business still make money consistently yearly for them and for us.
