      $SPX $QQQ $IWM History Says Fed Hikes Hurt More When Inflation Runs Hot

      Not every Fed hiking cycle plays out the same way. History points to two things that matter a lot for equities: 🌡️ Higher inflation when the Fed starts hiking has generally been associated with weaker stock market performance. ⚡ Faster tightening has also tended to create more pressure on equities. That distinction matters for $S&P 500(.SPX)$ $Invesco QQQ(QQQ)$ $iShares Russell 2000 ETF(IWM)$ A slow, measured hiking cycle is one thing. A Fed that has to respond to already-high inflation with aggressive rate increases is a very different setup. The headline may simply be “Fed is hiking.” The market reaction depends heavily on how hot inflation is and how quickly

      $1.3T Just Got Pulled Forward

      🔥 The most important number from tonight’s $NVIDIA(NVDA)$ earnings call wasn’t revenue. It was CapEx. CFO Colette Kress said top-five hyperscaler CapEx could hit nearly $800B in 2026 and $1.3T in 2027. That’s the key takeaway. The market had been looking for $1.3T in 2028. Nvidia just pulled that level forward to 2027. In other words, the AI infrastructure spending cycle isn’t slowing down. It’s accelerating. And that has a much broader read-through: 🔹 $Philadelphia Semiconductor Index(SOX)$ — the semiconductor complex 🔹 $Micron Technology(MU)$ — memory and HBM 🔹 $Lumentum(LITE)$ — optical connectivity 🔹

      Liquidity Is Driving the S&P 500

      It’s not just about AI hype. Liquidity remains a major driver of the market. The $S&P 500(.SPX)$ has been closely tracking Global M2 with an approximately 11-week lag, and that relationship is currently pointing toward a potential 8,200 level for the index. At the same time, the AI infrastructure boom is starting to show up in corporate earnings. Massive spending on data centers, chips, power, networking and related infrastructure is creating a broad earnings tailwind across the market. The combination of expanding liquidity and accelerating AI-driven earnings could provide the S&P 500 with another leg higher.

      $S&P 500(.SPX)$ realized vol dispersion is at levels last seen during the Dot Com Bubble unwind. In other words, individual stocks are diverging wildly from the index itself.

      The Chips Are Down

      We called the $Philadelphia Semiconductor Index(SOX)$ breakdown weeks ago, and it just hit my first downside target. Here's what comes next... When it rains, it pours. The selling pressure is starting to accelerate this week. It started overnight in Korea, where the KOSPI crashed -11% in a single session. Samsung fell -13% and SK Hynix fell -15%. Then the US opened, and it was another bloodbath for AI stocks today. Semis fell -4.5% on the day. At its lows, SOX traded down to $10,799. That was my first downside target. 🎯🎯🎯 I called for a SOX move down to $10.6k-$10.8k ~3 weeks ago (7/7) in “Chip Wrecked” (-11% ago). Today, we tagged my $10.8k target (at lows). Week after week, we have given it to you straight. We told you last Tuesday’s bounce was N
