Retail sales are falling, CEOs across a range of sectors are warning of macro headwinds, and the Federal Reserve expects to continue raising interest rates next year to bring inflation under control. If you're looking to take advantage of the sell-off, there are some gems in Berkshire's recent purchases (like TSMC and RH), and some other Buffett stocks are on sale as well, like Amazon -- which is as cheap as it's been in eight years on a price-to-sales basis. If there's a recession coming next year, somebody forgot to tell Warren Buffett.
