The Great Valuation Rotation Of The Roaring 2020s

Why It Matters

The rotation reshapes portfolio risk‑return profiles, prompting a shift toward mid‑/small‑caps and international markets, and reduces exposure to a potentially overheated AI‑centric mega‑cap segment.

Key Takeaways

• Large‑cap S&P 500 underperforms SMidCaps in 2023‑24.
• SMidCaps earnings rise, valuations remain attractive.
• US market share of MSCI hits 65%, prompting global shift.
• Magnificent‑7 forward P/E falls from 32 to 25.8.
• Non‑Mag7 S&P 500 P/E stable around 20.

Pulse Analysis

The past two years have seen a pronounced tilt toward large‑cap equities, driven by the pandemic‑induced rally in the S&P 500. As earnings growth for those mega‑caps slowed and valuation multiples stretched, investors began to scout for value elsewhere. Mid‑ and small‑cap stocks, captured by the S&P 400 and 600, posted flat earnings through 2022 but have since turned upward, while their price‑to‑earnings ratios remain comparatively low. This divergence has ignited a valuation rotation, rewarding the SMidCaps with stronger price performance and prompting fund managers to rebalance toward the under‑priced segment.

On the international front, the United States has dominated global equity markets, accounting for a record 65% of MSCI’s market‑cap weighting. Such concentration has heightened concerns about diversification and the risk of a single‑market correction. Consequently, investors are reallocating capital to regions where multiples are more reasonable, seeking both growth potential and a hedge against U.S. market volatility. This global rebalancing is reinforced by the perception that non‑U.S. markets offer a broader range of sectors less exposed to the AI‑centric hype that has propelled the Magnificent‑7.

The Magnificent‑7—Apple, Microsoft, Alphabet, Amazon, Nvidia, Meta, and Tesla—have faced scrutiny over the durability of their AI‑driven earnings surge. Their forward P/E has slipped from near 32 to roughly 25.8, easing fears of an imminent tech bubble reminiscent of the 1999‑2000 era. Meanwhile, the broader S&P 500’s non‑Mag7 constituents have maintained a stable forward P/E around 20, underscoring the relative attractiveness of diversified exposure. For investors, the key takeaway is to balance exposure: retain exposure to high‑quality growth while capitalizing on the emerging value narrative in SMidCaps and international equities.
