Market Warning From a Veteran Volatility Strategist
In a note that traders are watching closely, Cem Karsan, founder of Kai Volatility Advisors, warns that the S&P 500 could repeat a painful era of real-term losses if inflation stays stubborn and policy remains uncertain. The focus isn’t just on selling pressure or valuation gaps, but on the erosion of purchasing power that compounds over time.
Historical memory matters in markets, and Karsan points to a period when the index hardly moved in nominal terms, yet investors technically lost ground once inflation is accounted for. He stresses that real returns mattered more than headline gains for long-term savers and retirees who rely on their capital to keep pace with the cost of living.
“This isn’t about one bad year,” Karsan said during a recent discussion. “If inflation sticks and rates stay elevated longer than expected, the real value of a broad equity stake can shrink even as prices drift higher on the surface.”
The 1968–1982 Reference Point
To illustrate the risk, Karsan revisits a 14-year window in U.S. markets during which the S&P 500 produced little movement in nominal terms. In real terms, the purchasing power of an initial investment fell dramatically, underscoring a stark truth: money can look flat on a chart while households feel a squeeze in everyday goods and services.
During that era, the real value of the market eroded by roughly 40%, a figure that remains a cautionary tale for today’s investors who have not lived through a comparable inflationary regime. The point, Karsan notes, is not that stocks will never go up, but that the real path of wealth accumulation can bend against you for more than a decade if inflation remains above target and growth stalls.
Why The Warning Could Still Be Relevant
Karsan’s framework centers on the forward outlook for returns. He emphasizes that the longer horizon of 10 years tends to reveal the true texture of gains, not just the rate on paper. His takeaway is sobering: nominal outcomes often flirt with modest gains or losses, while real returns—after inflation—can bite much deeper.
- 10-year nominal forward returns have historically hovered near zero during periods of elevated inflation and mixed growth.
- Real forward returns, when inflation is sticky, have shown greater downside risk, raising alarm for long-term savers.
- In a similar cadence to the late 1960s and early 1980s, a regime of higher inflation can translate into a painful real erasure if not paired with durable earnings growth.
“The problem isn’t a one-off drawdown,” he explains. “It’s whether the regime can sustain higher prices without a corresponding lift in real earnings, which would support a lasting real-term recovery.”
Investing Implications For Today
As markets navigate 2026, the macro backdrop has seasoned investors modeling scenarios where inflation runs above central-bank targets for longer than anticipated. Recent data circles around inflation metrics that remain tricky to tame, complicating the fear/greed dynamic that often drives equity flows.
Market strategists are watching inflation indicators closely. The latest readings show a persistent gap between headline numbers and what households actually feel in their wallets. In this environment, the risk that karsan warns lost real could unfold again is a topic of serious discussion among portfolio managers who stress real wealth preservation as a core objective.
Inflation and Policy Context
Macro data in early 2026 painted a cautiously stubborn picture. Pain points for households persist when inflation outpaces wage gains, even as the economy continues to hum along in modest growth. The broader policy environment—comprising fiscal dynamics, debt levels, and central-bank communications—adds a layer of complexity for investors weighing equity exposure against the value of cash and fixed income.
- Headline PCE inflation around 3.5% year over year in March 2026, according to latest government releases.
- Core PCE, which strips out more volatile components, sits at about 3.2%, still above the Federal Reserve’s 2% target.
- Market pricing has shifted toward a careful posture, with investors considering the trade-off between growth, inflation, and the potential for policy shifts later in the year.
These numbers feed into the central question: could a period of real-term losses reappear if earnings growth fails to outpace inflation over a decade or more? That is precisely the line of inquiry Karsan is raising as a risk scenario for cautious long-only investors and those who rely on market-linked wealth to fund retirement plans.
What Investors Can Do Now
With the risk of a renewed real-term squeeze in focus, portfolio construction takes on a more conservative, real-return lens. Here are practical steps from researchers and risk managers who weigh similar scenarios:
- Strengthen the ballast: maintain a core allocation to high-quality, cash-flowing equities with durable franchises and strong balance sheets.
- Preserve purchasing power: diversify across asset classes that historically hedge against inflation, including certain real assets and inflation-linked strategies.
- Embrace a price discipline: be mindful of valuation, but also of earnings quality and the resilience of cash flows under rising price pressure.
- Manage risk calmly: reduce exposure to highly leveraged bets and prepare for periods where real returns lag nominal gains, even when the market holds up on the surface.
- Think in real terms: regularly assess your portfolio’s purchasing power, not just its dollar value, to ensure retirement plans stay on track.
For long-time investors and those near retirement, the warning encapsulated by karsan warns lost real remains a reminder that the cost of living can outpace market gains. The question is not whether stocks will soar, but whether they can deliver real wealth growth when the price level keeps moving higher.
Bottom Line
The phrase karsan warns lost real has become a shorthand for a scenario where inflation and stubborn policy deliver a multi-year headwind to real wealth. While markets may still deliver nominal gains at times, real gains require more favorable inflation dynamics and higher, steadier earnings growth. As of March 2026 data and the unfolding year, investors should remain vigilant about the long arc of purchasing power and the possibility that a renewed real-term squeeze could reappear if conditions worsen.
In an investing climate where the focus is shifting from flashy returns to durable, inflation-adjusted growth, the real-term risk highlighted by Karsan is a frame that many portfolio managers are embracing in their 2026 planning cycles.
