Lower Yields Leave Economic Risks Unresolved
Rates fell, and investors bought semiconductor stocks. The bigger economic problems are still there.

The Mispricing
Rates fell yesterday, prompting investors to buy AI and semiconductor stocks. Credit looked fine, long-term bonds stabilized, and small caps rose too. But the strongest buying was still in semiconductors and AI infrastructure.
That matters because strong rallies usually spread across more sectors while volatility falls. This rally was different: semiconductors jumped, defensive sectors lagged, and VIX rose. The move was bullish, but the setup was fragile.
Market Moves: Indexes Rose, Semis Led
From the May 22 close to the May 26 close, the indexes looked fine: SPY +0.7%, QQQ +1.8%, IWM +1.9%. Equal-weight stocks also rose, but less. Semiconductors led.
What Lagged
The rest of the market was less exciting. Energy, staples, healthcare, and financials lagged or fell. The sector split shows stronger demand for AI growth shares, without confirming an improvement across the economy.
Energy stocks fell even with geopolitical risk still unresolved.
Defensive stocks did not confirm a broad rally.
Healthcare lagged the high-growth trade.
Banks barely moved.
Rates and Credit Improved
The drop helped bonds and growth stocks.
The 30Y yield fell, but it is still high.
Long-term bonds stabilized, but did not break out.
Credit looked fine. No clear stress signal.
This is the key point: falling yields are not always bullish. Yields are still high, and they may be falling because growth is slowing. Yesterday’s rates move helped stocks. It did not establish that growth and inflation risks were resolved.
Inflation Expectations Are Still Too High
University of Michigan final May sentiment fell to 44.8, below the June 2022 trough. Year-ahead inflation expectations rose to 4.8%, and long-run expectations rose to 3.9%. That makes it harder for the Fed to ignore inflation and cut rates.
The Fed May Be Slow to Cut Rates
Waller said the Fed could remove its easing bias, and that the next move could be either a hike or a cut depending on the data. Slower growth does not guarantee rate cuts if inflation expectations keep rising.
Growth Data Are Softening
The PMI data still point to slower activity, softer hiring, and high cost pressure. That is why one day of lower yields helps, but does not fix the problem. Stocks can still rise despite these economic risks.
Crowded Buying
The semiconductor move was not random. The market has a simple playbook now: if rates stop rising and AI demand still looks strong, buy the next bottleneck. That can create sharp upside when fund managers and options traders chase the same stocks.
- Semis led the move: SMH +4.5%, SOXX +6.1%.
- Memory and AI infrastructure were still the cleanest AI trades.
- The Market Ear described semiconductor stocks as being in “full squeeze mode”: dips were bought quickly, and traders paid up for upside options.
- VIX rose even though SPY was up. That is not what a calm rally usually looks like.
Why This Is Fragile
Strong AI fundamentals can still produce bad entry points when buying is crowded. Crowded buying raises the risk of entering after most of the gains.
- Long-term yields fell, but they are still high enough to pressure growth-stock valuations.
- Inflation expectations are rising.
- Fed cuts remain uncertain.
- Leadership is narrow. If semiconductor stocks reverse, the index can fall too.
How to Trade It
For longs
Stay positive on AI infrastructure, but trim names that have risen sharply. Prefer lagging beneficiaries with real revenue exposure over the most crowded stocks.
For options
If upside options are expensive, call spreads limit risk compared with naked shorts. Put spreads get better after momentum breaks; before that, they can lose money while the rally continues.
For macro risk
Watch for the 10Y yield moving back above 4.56%, VIX rising on up days, semiconductor stocks losing leadership, and Michigan long-run inflation expectations staying near 4%.
