FOMO, YOLO, RINO: The quirkiest catchphrases explaining the surprising buoyancy of the stock market and economy

• Experts have struggled to find textbook explanations for the surprising economic buoyancy and stock-market rally of 2023. 
• Many commentators have instead turned to trendy catchphrases – such as FOMO and YOLO – to describe the behavior of investors and consumers. 
• Here’s a roundup of the quirkiest buzzwords used to comment on US equities and the economy.
