$SPX Is Near a Record. This Hasn’t Happened Since 2000

$S&P 500(.SPX)$ is sitting near a record high. But underneath the surface, the market looks very different. Only about 48% of S&P 500 stocks are currently above their 200-day moving averages, meaning roughly 52% are below. The index was just 0.44% from its record close on Tuesday. The last time the S&P 500 was this close to a record while a similar share of its components traded below the 200DMA was March 2000, according to Dow Jones Market Data. That doesn’t tell us what happens next. It does tell us that index strength is being carried by a relatively narrow group of stocks. The headline index can look healthy while the average stock underneath it tells a very different story. That divergence is worth watching. Markets are always mov

The Fed Hikes. P/E Falls. Stocks Can Still Rise.

The Fed starts hiking. Valuation multiples usually compress. That part is pretty consistent. Looking at the last 5 hiking cycles, P/E contracted every single time. 📉 But here’s the part that matters: P/E compression alone didn’t necessarily mean stocks went down. The median $S&P 500(.SPX)$ 12-month return after the first Fed hike was still +6.8%. So what actually determines what happens next? Earnings. 👇 If earnings keep growing fast enough to offset multiple compression, the market can still move higher. If earnings weaken at the same time valuations are contracting, that’s when the setup becomes much tougher. That’s the piece I’d be watching across: $S&P 500(.SPX)$
The Fed Hikes. P/E Falls. Stocks Can Still Rise.

$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.

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).
