Portfolio Building

Last December we published Riding the Wave: The Anatomy of Booms & Bubbles. In it, we argued that the AI spending boom would continue through 2026 without tipping into ‘bubble’ mania, and that the right posture was to stay overweight stocks while favoring US assets. Nine months on, we think that call has aged well.

With so much attention focused on what the Fed might do at its policy meeting this week, it’s a good time to look back at history to get a sense of how stocks might respond should policymakers hike rates as the market now expects. LPL Research had been characterizing the rate decision as a coin flip until Fed Chair Kevin Warsh’s hawkish comments at the Jackson Hole meeting and the strong August jobs report.

AI-driven healthcare innovation is creating strong investment opportunities by improving efficiency, expanding access, and delivering better patient outcomes.

A week of rising oil prices and higher interest rates sent stocks lower across the board as investors increasingly priced in the likelihood that the Federal Reserve (Fed) will begin a rate-hiking cycle at its September 16 meeting. Following the August Consumer Price Index (CPI) report, futures markets implied an 88 percent probability that the Fed will, or at least should, raise rates at next week's meeting.

Chris Galipeau discusses high-conviction insights that go beyond media headlines.

Demand for fixed income ETFs hit a historic high-water mark in September. Investors and advisors turned to fixed income ETFs at a record-breaking pace, driving 2026 net inflows of $446 billion past all-time levels with months to spare. The massive tide of capital arrives at a critical juncture.

In our final chapter for this series, we will dig into that exact question. Unfortunately, there is good and bad news, and it can be summed up in a single sentence.

Is the AI infrastructure buildout one big trade in credit? So far, the market seems to think so. Spread dispersion – differences in borrowing costs among issuers – across the financing chain remains limited despite sharp differences in underlying risk. This contrasts with equities, where performance has become increasingly differentiated.

As policymakers adapt to new leadership, navigate a challenging geopolitical backdrop and contend with meaningful internal debate over the path of interest rates, the stakes remain high. Below, we discuss what to expect from next week’s Federal Reserve (Fed) meeting and provide perspective on the recent rise of Treasury yields to multi-year highs.

Attractive yields and resilient credit conditions are creating opportunities across fixed income, but uncertainty around inflation and interest rates makes flexibility, selectivity and disciplined risk management especially important.

In Part III, the focus will center on practical applications of this discipline. In particular, how advisors can integrate the methodology into modern asset allocation, and why it offers an evolutionary leap for passive investing that’s available through exchange-traded funds (ETFs).

For many investors, a 401(k) is simply a retirement savings account. For high-net-worth families, however, it can become a sophisticated planning tool that supports tax efficiency, wealth accumulation, and long-term legacy objectives.

Equity markets generally moved lower as rising yields and energy prices created a more challenging backdrop. Higher yields can be particularly difficult for long-duration equities, where a greater share of expected cash flows sits further into the future.

The recent employment report provided reassurance that the US labor market remains resilient. The economy added 162,000 jobs in August; the previous two months’ gains were revised higher by a combined 55,000, and the unemployment rate held steady at 4.1%.

One or a few high-performing stocks can provide a big boost to portfolio values. But they’re hard to come by and often struggle to maintain their momentum over time. Because these stocks increase portfolio concentration, investors must balance the risk of overexposure against the tax cost of diversifying. A thoughtful, tax-aware plan may help bring portfolios back in line.

History suggests slower Fed tightening tends to support stronger market returns and firmer economic growth, while faster hikes typically deepen drawdowns.

While the name is new, Syzygy is not. Syzygy, formerly Research Affiliates, will extend our multi-decade sub-advisory relationships in asset allocation and long-only active equities and expand into other active diversification strategies in the coming quarters.

Portfolio Managers Jonathan Coleman and Aaron Schaechterle outline why they believe momentum in small-cap stocks relative to large caps can continue, highlighting favorable earnings growth prospects, appealing relative valuations, and other structural tailwinds.

2026 began with 10-year Treasuries right around 4%, which many viewed as a comfortable place. The comfort came from some simple math—2 plus 2 equals 4. The long-term real yield on the 10-year Treasury was around 2% and the Fed’s inflation target is 2%.

Market volatility persisted in August as investors were again forced to reassess escalating tensions and an exchange of military strikes in the Middle East, while softer labor-market data was countered by mixed inflation readings.

With so much attention focused on what the Federal Reserve (Fed) might do at its policy meeting next week, it’s a good time to look back at history to get a sense of how stocks might respond should the Fed hike rates as the market (barely) expects.

Benchmark-Free has been a flagship strategy for half of GMO's history. As we approach our 50th anniversary in 2027, Ben Inker reflects on our first 25 years of Benchmark-Free investing.

Elevated interest rates have investors scrambling for yield, and munis have been ready to answer the call with tax-exempt income.

For much of the past decade and a half, investors saw little reason to favor bonds over equities. Yields were low and returns were muted, especially in passive strategies. Equities seemed to offer a much clearer path to long-term capital appreciation. For many investors, bonds were, at best, ballast: a dull but generally stable component of a broader portfolio. Then the experience of 2022 had investors questioning even that view, as areas of high quality fixed income generated equity-like losses that eroded much of the prior decade’s real return.

As students get closer to making a final college decision, the last two years of high school are particularly important. Parents will want to review their financial strategy to meet the costs of college, including a review of current savings, financial and merit aid, scholarships and loan options.

On Friday, the August U.S. employment report surprised to the upside, with 162,000 jobs added during the month. Year to date, the labor market has shown impressive resilience, with hiring also becoming more balanced across sectors than in previous years.

When markets become volatile, many investors gravitate toward assets they perceive as “safe.” Cash, certificates of deposit (CDs), money market funds, U.S. Treasury securities, and high-quality bonds can all play an important role in a diversified portfolio. But “safe” doesn’t necessarily mean “risk-free.”

LPL Research analyzes rising U.S. debt, Treasury yields, and fiscal trends, highlighting implications for markets and investors.

Target-date funds have become a staple qualified default investment alternative (QDIA) because they help participants invest appropriately without requiring them to act. But as retirement nears, income needs become more pressing and financial situations diverge—a situation dynamic defaults seek to address.

Chapter 3 of this series ended with a simple question. If the math so plainly says avoid big losses, respect valuations, and mind your timing, why does so much of the industry preach the opposite?

Equity markets can be as difficult to forecast as the weather, yet investors often assume future return patterns will predictably follow recent trends. In today’s turbulent market climate, we think fundamental research can help investors build conviction in long-term company forecasts that may be obscured by the AI-driven cloud cover.

Labor Day signals more than summer’s end. It marks a return of focus to the economic and market forces that will shape the remainder of the year. From resilient earnings and record AI spending to rising bond yields and the midterm elections, there is no shortage of forces shaping the market outlook.

To kick off our fourth season of the Alternative Allocations podcast series, I sat down with John Bowman, CEO of CAIA Association, to explore the massive changes underway across our industry. John and I discussed CAIA’s seminal paper “The World Rewired,” and the implications for private markets.

The U.S. ETF market reached $16.4 trillion in AUM in August 2026, driven by record product launches and a defensive shift to Treasuries.

Chris Galipeau discusses high-conviction insights that go beyond media headlines.

If you look deeply into a speculative bubble, you can already see the collapse. If you look deeply into a market collapse, you can already see the bull market. The road up and the road down are the very same road. Even so, aside from knowing that our investment position presently requires a safety net regardless of shorter-term conditions – we have utterly no opinions, preferences, or scenarios about the market outlook even a month or a quarter from now.

It's been 40 years since I began my career on Wall Street and the lessons I learned along the way from some all-time investment greats always hold true.

After a week of traveling abroad to meet with clients and discuss our outlook for the US economy and financial markets, we returned feeling the need to address a growing misconception, both in the United States and overseas, regarding the differences between the US and Chinese economies.

The “K-shaped” divide endures even as it evolves. Higher-income households keep benefiting from equity gains, home price appreciation, and solid earnings, while lower-income households face mounting pressure from elevated costs and tighter credit. But recent data suggest the story is becoming more nuanced.

Cerulli projects a $2 trillion surge in advisor-held alternatives over five years, as interval funds reshape how RIAs access private markets.

After several challenging years, important parts of the health care sector appear to be reaching an inflection point. Policy uncertainty has weighed on pharmaceutical companies, constrained biotech funding has pressured the drug-development ecosystem and the normalization of pandemic-era has challenged select tool and device companies. More recently, however, several of these headwinds have begun to moderate.

For many investors, years of disciplined saving, equity compensation, business ownership, or a handful of exceptional investments can produce a portfolio that grows faster than expected. While that may sound like an ideal outcome, it can also create what we often think of as a wealth overhang: a situation in which the complexity of your wealth begins to outpace the financial plan supporting it.

Emerging-market (EM) equities have benefited enormously from the global AI investment boom. But headline market gains show that EM leadership has become concentrated in a handful of mega-cap technology stocks. In our view, today’s EM benchmark is far less diversified than many investors assume, creating opportunities to seek differentiated sources of return.

Famous market bubbles share some characteristics, but it's nearly impossible to predict how big a bubble might get and when one is about to burst.

Global fixed income and equity ETF strategies posted gains and saw inflows surge in August, even amid ongoing macroeconomic turbulence and elevated long-term borrowing costs. International equities maintained their year-to-date lead over U.S. stocks throughout the month, led by notable strength in emerging markets.

Stocks have enjoyed a powerful run off the spring lows and have largely shrugged off concerns around growth, inflation, higher interest rates, the effects of artificial intelligence (AI), geopolitics, and policy uncertainty. As the calendar turns to September, however, they are entering what has historically been, from a seasonality perspective, the most challenging month of the year for equities.

Kevin Warsh's Jackson Hole speech struck a decidedly hawkish tone and was arguably the clearest signal yet that the Federal Reserve is actively considering additional tightening. Markets responded by raising the probability of a September hike to roughly 60% and pricing approximately 60 basis points of cumulative tightening through the middle of next year.

With recent data weakening the case for an immediate increase in rates, markets have sharply pared expectations for near-term tightening, with a hike no longer fully priced before early 2027.³ This moderation in rate-hike fears has been supportive for gold.

Anchoring is one of the most powerful—and underestimated—forces in financial decision‑making. Once an emotional label attaches itself to an idea, it becomes the lens through which people interpret everything that follows.

House poised to pass bill to avoid government shutdown, two new members set to join the House, Fed chair speech boosts rate hike possibility, and national debt hits $40 trillion.

Geopolitical headlines can quickly move markets, but investors do not need to predict every headline to identify potential opportunity. The more useful question is what governments, businesses and consumers are doing in response to a changing strategic environment, and which companies may benefit.

The month of August reminded many investors that the markets rarely move in a straight line. A combination of encouraging economic fundamentals, uncertainty in the bond market and renewed geopolitical turmoil led to increased volatility and shifting market leadership. But the underlying backdrop reinforced that the US economy continues to expand at a sustainable pace.

US Treasury Secretary Scott Bessent made waves with his recent announcement that the Treasury would at least double the size of its buybacks of long-term debt in the coming months. He argues that long-term yields do not reflect fundamentals, suggesting that the Treasury's intervention is aimed to restore proper market functioning.

August was a good month in financial markets, with the S&P 500 up around 2.7%. The market leaders came from the commodity complex, with gold and bitcoin (not sure how this should be classified) being the two top performers.

This summer has delivered "blockbuster" returns, both positive and negative, while the possibility of quick and seemingly easy gains continues to draw investors toward speculative areas of the market. In his latest insight, Richard Bernstein, Global Head of Macro & Customized Investing, shares five charts that cut through the noise and highlight important shifts in credit creation, inflation, global growth, market leadership, and asset class performance.

Record fixed income ETF inflows in August pushed year-to-date ETF totals past $1.4 trillion, with short-term bonds leading the surge.

Highly concentrated US equity markets have been a consistent theme in recent years. Now, after the latest reconstitution of a major US equity benchmark, concentration is taking on a new form, with the Magnificent Seven’s grip loosening and semiconductor stocks gaining more influence. In essence, millions of passive investors received a new portfolio without making a single decision.

AI-driven scarcity is allowing companies perceived as lower quality to post the revenue growth, margin expansion and rising returns that investors associate with quality, lifting estimates, multiples and stock prices.

The high-yield market appears expensive at first glance. Spreads sit near the tight end of their historical range, which implies limited compensation for credit risk. However, spreads relative to their historical levels do not capture the full opportunity set of the asset class. Corporate fundamentals remain healthy, defaults are low, and the quality of today’s high-yield universe is higher than its long-standing reputation might suggest.

The backup in global yields since late February has reignited the debate over the potential knock-on effects for corporate borrowers, particularly through higher refinancing costs and weaker debt-servicing capacity.

Should the recent value rotation be viewed as a regime shift-driven change in market preference, or a simple reversal trade? We think there is a compelling case to be made for the former. In a regime of higher interest rates and stubbornly above-target inflation, the market is increasingly focused on capex intensity, free cash flow conversion, and the cost of capital.

State Street’s top inflows for its SPDR ETFs during the year-to-date period and the past four weeks suggest that while investors have confidence in U.S. large caps, they’re still looking to hedge their bets by allocating to gold.

Despite ongoing geopolitical tensions, growing questions about the scale of AI-related spending and steadily rising bond yields, market volatility remained remarkably subdued this summer.
