Warren Buffett's $365 Billion Portfolio Dominated by Singular Stock Investment

Almost half of Warren Buffett-led Berkshire Hathaway's $365 billion portfolio is invested in Apple. Buffett was attracted to Apple due to its strong consumer brand, financial stability, and cheap valuation. However, Apple's current valuation is much higher than when Buffett first invested, and the company may not have the same growth opportunities as before. As a result, it may not be a smart investment at this time.
