The Stock Market Has Done This Only 2 Times Since 1871 — and Both Times Ended Badly. Could Trump’s Policies Raise the Risk of Another Market Meltdown?

The S&P 500 Shiller CAPE ratio is slightly above 41—only the dot-com era (late 1999/early 2000) and 2021 previously topped 35—raising the risk of another major downturn if history rhymes. The article links this to Trump-era policy pressures including steep tariffs (widely cited as lifting near-term inflation) and the Iran conflict driving oil higher, while CME FedWatch shows an 87% odds of a Fed hike by year-end. It flags a key offset: robust earnings growth is pushing the forward earnings multiple down rather than up, which could weaken the CAPE signal’s predictive power.

Analysis

Elevated market valuation is not, by itself, a timing signal; it mainly means the market has less room to absorb a rate shock. The immediate vulnerability is in the highest-duration parts of the index: if inflation expectations or real yields move even modestly higher, multiple compression can hit QQQ and SPY faster than fundamentals deteriorate. That makes the next 1-3 months a discount-rate story, not an earnings story.

The cleaner relative winner is CME, because policy uncertainty, tariff pass-through, and yield volatility should support options and futures activity. A second-order effect is that passive, cap-weighted exposure becomes more fragile when a handful of mega-caps stop masking weakness elsewhere; that broadens downside even if index earnings are still growing. Small caps and levered balance sheets are also exposed to higher refinancing costs if the market starts repricing the Fed path.

The contrarian view is that the consensus may be overpricing the speed of any drawdown. Strong earnings revision breadth and buybacks can keep forward multiples from contracting immediately, which means the setup is more likely a grind higher in volatility than an abrupt crash. What would falsify the bearish tape-risk thesis is a benign CPI/PCE sequence, stable 10-year yields, and continued upward EPS revisions over the next quarter.

Key Decisions for Investors

• Long CME vs. short QQQ on any yield spike or tariff headline: express as a 1-3 month pair trade; thesis is that higher policy volatility monetizes at CME faster than it hurts index multiples.
• Buy 3-6 month SPY or QQQ put spreads only if the 10-year yield breaks higher and Fed cut odds are repriced down again; this is a defined-risk way to play valuation compression without needing a crash.
• Avoid adding to high-duration growth exposure until inflation data confirms disinflation; if forced to express the view, prefer a temporary underweight to NVDA/NFLX-like long-duration names versus equal-weight or value baskets.
• Set an alert on the next two core inflation prints and the 10-year yield regime; if yields stay contained and earnings revisions remain positive, cover any defensive hedges because the valuation signal is likely to be early, not wrong.
