BILLIONAIRE investor Warren Buffett had to significantly scale down Berkshire Hathaway's annual shareholder meeting - held on May 2 - to avoid the risk of his hometown of Omaha becoming a Covid-19 hotspot.

Yet, there has probably never been a more crucial moment to observe Mr Buffett's insight and wisdom. In particular, the owner-oriented philosophy that Mr Buffett applies in stock investing as well as in running Berkshire could help investors get to grips with the growing number of companies that are slashing or cancelling their dividends.

The key point that Mr Buffett constantly emphasises is that investors should not think of shares issued by a company as mere pieces of paper with a quoted market price, but an entitlement to a slice of the company's business and assets. Mr Buffett applies this principle consistently whether he is discussing the affairs of Berkshire itself, or the many US-listed companies in which Berkshire holds major stakes, which include Apple, Coca-Cola and Bank of America.
