      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

      If the S&P Rolls Over, Chips Could Feel More Pain

      We are seeing what a crowded trade unwind looks like. Semi ETF inflows went parabolic this year with $46B coming in <7 months YTD. This is more than the previous 9 years COMBINED. Now, it’s unwinding. $iShares Semiconductor ETF(SOXX)$ $VanEck Semiconductor ETF(SMH)$ $Roundhill Memory ETF(DRAM)$ $Philadelphia Semiconductor Index(SOX)$ “Trump has to do something soon” Trump doesn’t care about AI Bubble stocks getting torched. The SPX is down ~2.4%. CTAs haven’t even started selling yet. If the $S&P 500(.SPX)$ starts to roll over, this will become another big headwind for stoc

      Tuesday was the 11th time since 1999 that High Beta Momentum gained 7%+ while above its 200 DMA. 4 of those 11 have happened in 2026‼️ 3 came in early 2021. 3 came in early 2000.
