What Matters About Market History, and the Worldwide Bull Market

Motley Fool Money · The Motley Fool — Robert Brokamp interviews Ryan Dietrich (Carson Group Chief Market Strategist) · February 28, 2026

Chapter Summaries

Chapter 1: The Worldwide Bull Market — Opening Data 80% of 70 global stock markets tracked by Thomas of Top Down Charts are up at least 20% off their 52-week lows — a reading rarely above 50% over two decades. Previous spikes at this level occurred in 2003, 2009, and 2020, all excellent buying periods. The 2026 US rally is the broadest ever: a record number of individual S&P 500 stocks are outperforming the index. Notably, the Mag-7 (minus Tesla) now trade at a forward P/E below consumer staples, which are up ~15% YTD. Mortgage rates dropped to 6% (lowest since 2022, down 80 bps from a year ago). Home Price Index growth slowing (annualized 1.3% in December). HELOC total reached $434B (up 36% over 4 years). Key stat: the S&P 500 has been profitable or lost less than 10% in 88% of calendar years since 1928. Only 12 years out of ~97 saw 10%+ declines.

Chapter 2: Does Market History Still Matter? Ryan Dietrich (Carson Group) argues: fear and greed never change; what drives markets long-term — earnings, profit margins, the Fed — also hasn’t changed. History is a guide, not gospel. Spurious correlations (e.g., NFC Super Bowl win correlating with S&P returns) are fun but not investable. What matters is the macro backdrop: follow the hard data, not consumer sentiment (which is near pandemic lows even as retail sales and auto sales remain strong). Carson Group has been bullish for three years despite being mocked for it.

Chapter 3: Three Things That Matter Most — Earnings, Breadth, Credit Dietrich’s framework for the market:

  1. Earnings: At record highs. Profit margins at record highs. Q4 2025 revenue is among the best in four years.
  2. Market Breadth (Advance-Decline Lines): S&P 500, NYSE, mid-caps, and small-caps all hit new all-time highs or 52-week highs in their advance-decline lines the week of this episode. In the late 1990s, market breadth peaked and rolled over before the crash — warning signs absent today. This is a healthy, rotating bull market.
  3. Credit Markets: High-yield spreads and investment-grade spreads are calm. Credit markets didn’t stress during the 2023 regional bank crisis, the August 2024 Yen carry trade unwind, or Liberation Day. “The credit markets are the smartest people in the room” — if they’re not worried, the broader picture is likely fine.

Chapter 4: The Global Economy Is Firm Emerging markets and developed international economies are growing. Copper (“Dr. Copper”) is flirting with all-time highs — historically a reliable indicator of global economic health. Business investment is strong. AI capex shows virtually no slowdown. Consumption is solid. Housing has been a drag (negative for GDP 6 of 7 quarters), but the $37-38T US economy has isolated this weakness. The global picture is broadly positive.

Chapter 5: Inflation at 3% — Why That’s Acceptable The Fed’s 2% target is a wink-wink goal; historically, inflation has averaged 3.5% over 150 years. Carson Group has been positioning for a 3% inflation world (not 2%) for years. Core PCE is at ~3% YoY — while this sounds bad given the Fed’s target, the economy and markets are holding up fine. The deflationary anchor: shelter is 42% of core PCE and is running negative year-over-year in private data (Zillow, Apartment List), though government data is delayed. Commodity prices add upward pressure. Net result: inflation likely stays around 3% rather than returning to 2%. Carson’s portfolio adjustment: slightly less bonds, slightly more stocks, with some gold and managed futures for inflation protection.

Chapter 6: Software Stocks — Buying Opportunity? One year ago, DeepSeek dominated headlines; it proved to be a buying opportunity, not a structural threat. Dietrich draws a parallel: current software selloffs are “throwing the baby out with the bathwater.” Software as a sector is the cheapest it’s been relative to the S&P 500 since 2013. Carson Group has been buying broad-based technology ETFs and software ETFs. Their view: in six to nine months, large-cap tech and Mag-7 won’t look dead — this will look like another volatility episode, not a structural collapse. Key caveat: yes, some specific companies/industries are genuinely disrupted by AI (they acknowledge this), but many solid-moat software businesses have been unfairly dragged down.

Chapter 7: Long-Term Investing Discipline For long-term investors, short-term seasonal signals should matter “very little.” The best investors are those who contribute to 401(k)s consistently and look up decades later at wealth. Key mindset: volatility is “the toll we pay to invest.” Historical averages: ~7% pullbacks per year, 10%+ correction once a year, bear market every 3-3.5 years. Planning advice from Eisenhower: “Plans are useless; planning is everything.” Know going in that a 15% peak-to-trough correction is normal. When it happens (and it will), don’t panic. The people who held through April’s 20% drawdown and didn’t sell made the right call.

Chapter 8: Personal Finance Advice — Financial Health Week The Motley Fool runs an annual Financial Health Week where employees use company time to tackle personal finance tasks (budgeting, benefits review, estate planning, insurance, retirement planning). The suggestion: even without a company program, hold your own “financial health day” — block your calendar, limit distractions, and spend a few hours on lingering money tasks. Quote from James Clear: “Your net worth is a lagging measure of your financial habits.”


Summary

Ryan Dietrich of Carson Group presents a data-driven case that the bull market remains healthy and intact, with software stocks representing the most compelling value opportunity since 2013. Despite consumer sentiment near pandemic lows, the underlying hard data — earnings at records, credit markets calm, market breadth at all-time highs globally — supports continued optimism.

Investment advice and actionable insights:

Stay overweight equities. All three of Dietrich’s most important signals are positive simultaneously: record earnings/profit margins, strong advance-decline line breadth (the “life-blood of markets”), and calm credit spreads. This combination has historically indicated a healthy bull market, not a top.

Buy software stocks and broad tech ETFs. Software is the cheapest relative to the S&P 500 since 2013. Carson Group is actively purchasing broad-based technology ETFs and software ETFs. The DeepSeek parallel is instructive: the last major tech fear (a year ago) was an excellent buying opportunity in hindsight. Caveat: some specific companies facing direct AI disruption (e.g., IBM, legacy legal tech) may have structural issues that don’t resolve simply with time.

Position for 3% inflation, not 2%. Slightly reduce bond exposure relative to historical norms. Add gold and managed futures as inflation hedges — these positions have worked well for Carson over the past several years as inflation stayed above target. Don’t assume a return to 2% inflation; shelter data (the biggest component of core PCE) is the key variable to watch.

Monitor copper as a leading global indicator. Copper near all-time highs is a strong signal of global economic health. A sustained copper decline would be an early warning sign worth paying attention to.

Expect and plan for corrections; don’t react to them. A 15% peak-to-trough pullback is the historical average per year since 1980. Know this in advance so you don’t panic-sell when it happens. The April 2025 20% drawdown that resolved itself is the most recent example.

Don’t chase the last three years’ winners. Mag-7 outperformed for three straight years — statistically, the probability of a fourth straight year of leadership is lower. Diversification into other sectors (including international) is warranted.

Personal finance action: Schedule a “financial health day” — block your calendar and work through estate planning, insurance review, beneficiary updates, and retirement account optimization. These tasks compound over decades.
