Article contentWe are not calling for the demise of Nvidia Corp., the current AI star. However Alphabet Inc. has exposure to AI, but also to many other high-growth areas such as cloud computing, quantum computing, YouTube, Waymo, SpaceX and so on. Nvidia, despite its attractions, is still essentially tied completely to AI. Alphabet shares rose about 60 per cent so far this year and Nvidia is up about 25-30 per cent. Nvidia’s market cap is about US$4.3 trillion, and Alphabet is at about US$3.7 trillion. Alph ...

Let me preface any discussion by noting that I'm a long-term investor at heart. The overwhelming majority of the three dozen securities in my portfolio (35 stocks and one exchange-traded fund) have been held for at least one year, with a couple of positions surpassing the decade mark. My investment philosophy is modeled after that of the soon-to-be-retired CEO of Berkshire Hathaway , Warren Buffett.With an understanding that pricier stock markets come with the heightened risk of weaker annualized returns an ...
