Even though Warren Buffet's investing reputation has declined in recent years with Berkshire Hathaway's performance, a questionably close relationship with Bill Gates, and the surge of successful retail meme stock and crypto investors - the Oracle of Omaha is still the iconic role model that many investors inspire to be.
When Warren Buffet speaks, the markets react.
Warren Buffet is most known for his value investing strategy - the core concept being a heavy focus on a company's fundamentals, a strong moat or competitive advantage, profitable with straightforward cash flows/growth horizons, long-term intrinsic value, and stable intuitive products.
Berkshire Hathaway's portfolio is filled to the brim with stock of companies that match this strategy such as Apple, Bank of America, Wells Fargo, Kraft, Coke, Verizon, General Motors, IBM, and Intel.
Companies whose products you can understand easily and would safely sell no matter how much the world changes.
You need to put money in a bank.
You need a phone and a data plan.
You don't want soda, you want Coke.
To go anywhere far means taking a plane.
