Renowned economist Ed Yardeni is calling for the S&P 500 to hit 11,000 by the end of 2029, betting big on what he's framing as a "Roaring 20s" economic boom ahead. The projection reflects optimism about sustained economic expansion and market momentum over the next few years. For investors across asset classes—including crypto participants tracking macro trends—this kind of bullish longer-term outlook on traditional equities contextualizes the broader sentiment cycle we're in. Whether the rally materializes depends on inflation control, policy decisions, and global economic stability, but the narrative underscores why many see this decade as pivotal for growth positioning.
