Bond Yields Storm September as AI Capex Carries the Tape

Andrew@CANSLIM RESEARCH

The Bond Market Is Now the Only Story That Matters

September has arrived with a familiar but dangerous setup. Rising global bond yields, fresh Middle East tensions, and higher oil prices are all hitting the tape at once. The U.S. 10-year yield sits at its highest level since early 2025. This move is not isolated. Yields are climbing in Japan, the U.K., Germany, and Europe as traders reprice inflation and policy risk. For growth investors, this is the primary threat. Higher discount rates hit long-duration names first, and chip stocks are especially vulnerable. The market’s focus has shifted sharply from the AI narrative to the bond market. Global social sentiment confirms this, with users posting screenshots of the 10-year approaching 4.8% and the 30-year “going vertical.”

Oil Shock Rekindles Inflation Fears Across the Globe

The catalyst for the yield spike is geopolitical. Two supertankers were attacked in the Strait of Hormuz on Monday night. One was Saudi-owned, the other South Korean-financed. This re-escalates the six-month U.S.-Iran conflict and puts the crude oil risk premium back into prices. Energy is one of the few sectors bucking the trend. USO closed at 133.72 (+3.10%), while XLE finished at 63.93 (+2.03%). Higher oil feeds directly into inflation expectations. That makes central banks less likely to sound dovish. The online crowd sees a clear chain: tanker attacks, higher oil, sticky inflation, hawkish central banks, and crushed valuations. The fear is palpable, but actual panic indicators are absent. The VIX has failed to rise above 16, which the community mocks as “a VIX for ants.”

AI Capex Is Propping Up a Narrow and Fragile Growth Story

Under the surface, the growth story is still powered by AI infrastructure spending. One analysis argues AI-related spending may have accounted for a very large share of Q1 GDP growth. The Fed itself says most of the recent strength in business investment is tied to AI infrastructure. This helps explain why the economy can look stronger than the rest of the market feels. Growth is supported by a narrow but huge capex boom, while the broader tape is fragile. The GDP picture may be flatter than the headline suggests if AI capex is carrying such a heavy load. This is a double-edged sword. It keeps the economy afloat, but it also means a slowdown in AI spending would hit both growth and earnings simultaneously.

The Online Crowd Smells a Bull Trap in Tech’s Late Rally

Monday’s close planted land mines for today. SPY fell -0.31% to 766.87, and IWM dropped -0.63% to 293.89. But QQQ barely closed flat at 716.69 (+0.03%) after a late-session rally. Global social sentiment called that final green candle a “textbook bull trap.” The divergence is telling. The broad market is weak, but a few large tech names are holding up. This is not healthy breadth. It is concentration. Meanwhile, GOOGL fell -2.15%, and MRVL dropped -2.27%. The only bright spots were TSLA (+5.50%), MU (+2.76%), and SNDK (+5.65%). But the featured chart for SNDK shows the weakest technical pattern of the group. That is a warning sign for momentum traders.

Retail Sentiment Is Fearful but Greedy at the Same Time

The community atmosphere is extremely pessimistic but charged with self-deprecating excitement. “SeptemBEAR” is flooding the boards. Many are shouting “panic-sell everything” while simultaneously discussing which dip to buy at the open. The estimated fear level is around 75/100. But this is a strange form of fear. One user posted, “My portfolio fell from 440,000 to 210,000,” while another said, “90% fear, 95% greed; this isn’t zero-sum.” The real divide is not between bulls and bears. It is over whether “this time there is finally no TACO.” Most acknowledge that interest rates and oil prices cannot be fixed by a single post. The market makers are keeping the VIX suppressed, but the underlying tension is real.

The Path Forward Depends on Yields, Oil, and Earnings Growth

The near-term driver remains the bond market. The question is how far yields extend and whether oil holds these gains. A minority offers a constructive path: Bessent’s strategy is to push debt toward the short end, wait for a recession, and then switch back into long maturities. But the broader view is that limited ammunition cannot hold back the global bond market. For growth investors, the key is to watch whether AI spending keeps propping up growth enough to offset tighter financial conditions. If earnings grow faster than bond yields, valuations can hold. If earnings slow, the market has a problem. The setup is fragile, and the tape is narrow. Leaders like SNDK are showing technical weakness. That is not the time to add risk. It is the time to respect the bond market and wait for clarity.
