Hi Traders,

On days when the S&P 500 closed green, more stocks finished red than green. Some sessions ran 350 down against 150 up. On days the index closed red, it flipped: 350 up, 150 down.

That happened over and over for a month. The scoreboard said one thing and the field said the opposite, and it said it almost every single day.

The month-end math tells the same story. The S&P 500 finished July lower while 59 percent of the stocks inside it finished higher, and on July 27 the equal-weighted version of that index, which counts every company the same instead of letting the biggest ones dominate, closed at a record high.

I've been doing this since 2001. I've never watched a month where the index number was a worse description of what actually happened to stocks.

On July 11 I told you I expected the market to broaden away from the AI trade and into the real economy. The size of that broadening surprised me.

Here's the part worth keeping. July didn't produce one misleading number. It produced three. The index, the inflation print and the Fed decision each stood in for a crowd that wasn't doing what the number said.

The Index Turned Into a Semiconductor Quote

Semiconductors did the damage, and semiconductors are where the crowd was positioned.

The VanEck Semiconductor ETF (SMH) dropped more than 19 percent in July, its worst month since 2008. When one crowded group carries that much weight, the index stops measuring the market and starts measuring the group.

So the index turned into a semiconductor quote with 490 other companies stapled to it.

Cboe put a number on it. In the week of July 20, Mandy Xu reported the SMH versus SPX one-month implied volatility spread, the gap between what options say chips will do and what options say the index will do, hit a record 44 percent, more than five standard deviations above average. Five S&P sectors rose that same week while the broad index fell. Here is the report.

That same report has the other half of the picture. Russell 2000 one-month implied volatility rose a single point to 19 percent, and options now price small caps as calmer than large-cap technology. The wild child of the market is currently the safe seat.

Read that again. The options market priced a record disconnect between the index and its own components. Traders paid real money for that disconnect before anybody wrote the story.

The dispersion data says it plainly. Cboe's DSPX index, which measures how differently traders expect individual S&P 500 names to move compared with the index itself, hit a six-year high of 47 percent in the week ending July 10. That beat the peak from the April 2025 selloff, when the VIX touched 60. The VIX during July's reading sat at 15. That digest is here.

The money went somewhere boring. Energy led, and the Energy Select Sector SPDR Fund (XLE) added roughly 15 percent on the month behind crude. Banks, oil, drugs and railroads.

June's Disinflation Came From a Gas Pump

Same lesson, different number.

June's CPI read like a turn. Headline fell to 3.5 percent from 4.2 percent, and core, the version that strips out food and energy, came in flat on the month.

Then read the composition. Energy fell 5.7 percent for the month, its largest one-month drop since April 2020, and was the single largest contributor to the decline, more than offsetting increases in shelter and food. Gasoline alone fell 9.7 percent. The BLS release is here.

That drop followed energy gains of 3.9 percent in May, 3.8 percent in April and 10.9 percent in March. One month of relief inside a rising series isn't a trend. It's a ceasefire.

The same release carries the number almost nobody printed. Over the 12 months through June, energy is still up 15.7 percent and gasoline is up 26.7 percent. The month looked like disinflation. The year looks like an energy shock with one good month buried in it.

Core disinflated too, from 2.9 percent to 2.6 percent, and I'm not going to pretend otherwise. But core excludes energy by construction, so of course it looks clean. Energy doesn't stay outside core forever. Airline fares are up 26.5 percent over the year. That's jet fuel wearing a different jacket.

And the ceasefire didn't hold. On July 29, WTI crude jumped 6.6 percent to settle at $84.46 after Iran targeted American forces in the Middle East.

The Long End Didn't Buy the Hold

The Fed held at 3.50 to 3.75 percent on July 29, the fifth straight hold. The headline says pause.

The vote says something else. Nine to three, with Beth Hammack, Neel Kashkari and Lorie Logan all wanting a hike. That's the most dissents in one direction since September 2016. Chairman Kevin Warsh called it a "good family fight." The statement is here.

Then the bond market split in half.

Short-dated traders read the hold and stood down. The two-year yield fell four basis points to 4.236 percent, and swaps trimmed the odds of a September hike. The long end went the other way entirely.

The 30-year jumped more than 10 basis points to 5.20 percent, touching 5.244 percent intraday, its highest since July 2007. The 10-year climbed to 4.67 percent. One market read the decision. The other read the room.

Those three dissenters don't need a new argument. They need one CPI print with energy back in it, and crude just handed them the setup.

What This Actually Costs You

An index is an average. A CPI print is an average. A Fed decision is a vote count standing in for a room that doesn't agree.

Every one of them is a single number covering for a distribution, and in July every one of them covered badly. If you sized your risk off the index last month, you were sized for a market that didn't exist.

I didn't find the rotation names by reading. I found them on a momentum scanner. JPMorgan Chase (JPM), Bank of America (BAC) and Valero (VLO) all showed up on the scan on , while everyone else was still writing about the semiconductor correction.

The scan doesn't know what the story is supposed to be. It only knows what's moving. That's the whole point: when the average is lying, the distribution is the only honest information left, and something has to read it for you.

Over the next few weeks I’ll tell you more about my various scanners and the option trading service I’m building that takes advantage of them all.

Enjoy the process,
