The S&P 500 is 60% above its post-World War Two trend line, Jim Paulsen said, and trailing earnings per share are at a record against that same trend.
Most of the argument on Wall Street this summer has been about inflation and what the Federal Reserve does next. Paulsen said the thing that ends the run is the opposite worry, and that a correction by year end is what it looks like.
"And I just think the collision of that is going to lead to some kind of gut check here."
Paulsen was chief investment strategist at the Leuthold Group, writes the Paulsen Perspectives newsletter, and came on with a published call that the S&P could correct by year end, including a bear market in technology.

Key Takeaways
The S&P 500 sits 60% above its post-World War Two trend line Trailing 12-month earnings per share are at a record against that same trend
Record profit margins sit alongside a record low share of the economy going to wages
Households hold the most stock and the least cash on record, so they cannot buy more Sentiment is not euphoric, he said, it is complacent
Nobody has had to price a recession for 16 years
The catalyst he expects is a growth scare rather than an inflation scare Citigroup's economic surprise index has fallen from 63 in June to 17
Two sectors are carrying the entire earnings story Technology and communications estimated earnings are growing at a 90% annualized pace The other seven sectors, about half the market, are growing at 6%
1. September and October
Quintanilla asked what causes the correction, with four months of the year left.
Paulsen started with the calendar, saying the market is heading into what has historically been the worst seasonal part of the year, September and October
The seasonality is not the argument, though. His case is that the market has built up a stack of vulnerabilities that a bad season would expose
He said he does not expect this to settle the direction of the market for long: "I don't think it's a bull market or bear market. And I think that next year we'll have a good one."
2. Records on every measure
The starting point is the level of the index against its own long-run path. "I look at the price of the S&P 500, it's 60% above its historic post-World War Two trendline average."
Earnings per share on a trailing 12-month basis are also at a record high relative to that post-war trend line, he said, which leaves little room for either measure to advance much further without a pause
Corporate profitability is at the same kind of extreme, and it has a mirror image in what workers are paid. "If I look at profit margins, they're at record highs for corporate america." "You look at the same time that labor compensation to GDP is at a record low."
The cost lever is used up too. Net investment by corporations as a percentage of GDP is at a record high, he said, so spending more in order to cut costs has already been done
Valuations are the one measure not at a record, and only just. "Then you look at valuations. They're not at record highs, but they're very close."
3. Investors are all in
Positioning is the part of the argument that does not depend on a forecast. "If you look at investors, they're all in."
The national accounts data is what he pointed at: "I mean, from the national accounts, the households equity holdings as a percent of total financial assets are record highs and their household cash holdings to the market capitalization of the stock market is close to record low." The consequence he drew: "So there's not a lot of room for them to increase their exposure, if you will."
Sentiment is not the extreme, and that is his point about it. "And if I look at sentiment I wouldn't say it's ecstatic or it's extremely pessimistic, but it's certainly complacent." "I think a lot of people think they can continue to buy on the dip." He said they have done it successfully over time
The reason nobody prices a downturn is that most investors have not seen one. "Nobody's worried about recession anymore because we haven't had 1 in 16 years for all practical purposes."
4. The pressures arriving now
Against that stack of vulnerabilities, he listed what is pressing on the market today. "And then we got these vulnerabilities and now we're putting pressure on it with higher oil prices, higher inflation, with higher bond yields, with the hawkish Fed, with real money growth in the last year has been growing at 1.5%." Real money growth is the money supply after inflation. At 1.5% a year, he said, it does not leave much room for the economy itself to grow
The currency is the last of them, and he called it restrictive. "Doesn't leave much room for real GDP growth with the dollar in real terms, that's within 10% of its all time high, a very restrictive force."
His conclusion from the list is a shakeout rather than a regime change. "And I just think the collision of that is going to lead to some kind of gut check here."
5. Recession replaces inflation
Quintanilla put it back as a question about the trigger: the market is near priced to perfection, so what is the catalyst, and does a correction led by technology mean something in the AI build-out has to break first?
Paulsen allowed that as one route but said the real change is in the data underneath. He said everyone is focused on inflation while real economic activity is slowing again
The measure he used to date the slowdown is a surprise index. "Again, the Citigroup economic surprise index was 63 in june. It's now 17." A surprise index tracks whether incoming data is beating or missing forecasts, so a falling reading means the data is coming in short more often
Momentum is coming down in the consumer sector, he said, and named retail sales and housing in particular
He does not accept the official description of the labor market. Paulsen said it is interesting to him that officials keep calling the job market firm, steady and healthy when job growth over the last year has been two tenths of one percent
The catalyst, then, is a change in what investors are afraid of. "I think people are going to get more worried about recession than they are about inflation, and that could be the catalyst."
6. Half the market grows 6%
The second half of his case is that the earnings growth everybody cites belongs to two sectors. "In addition to that, the earnings of the S&P overall are not fantastic. They are in certain segments."
Technology and communications are the segment doing the work. "The tech and communications sector, their estimated earnings this year are up at a 90% annualized pace."
Materials and energy are second, on the oil price. "And materials and energy companies, those estimated earnings are up at a 50% annualized pace tied to what's going on with oil prices."
The other half of the market is growing at a fraction of that. "But the remaining seven sectors of the S&P 500, their estimated earnings market cap weighted, which makes up about half the market. Those earnings are up 6% annualized this year on a forward one year basis." "And if you back out inflation basically they're growing real earnings at about 2.5% pace."
Bonus Insights
The programme's market read immediately before the introduction had West Texas Intermediate crude up about 2.3% on the day at $87.71 a barrel — the same higher oil price Paulsen named minutes later as one of the pressures on stocks
Quintanilla used Paulsen's own label for the sectors at risk, describing a correction led by technology and by what he called the "new era" sectors, communications included
Paulsen's bottom line is that the market has run out of room on its price against trend, on profit margins and on how much stock households can hold, and that what exposes it is a growth scare rather than the inflation everyone is watching.
