Factor-Based Investing

Vigilante movies have always been popular with audiences. From Clint Eastwood (Dirty Harry) to Halle Berry (Catwoman) to Denzel Washington (The Equalizer), characters that take justice into their own hands when systems fail are seen as heroes.

VettaFi has experienced strong growth as a differentiated index provider in 2026. This momentum continues with today’s acquisition of The SPADE® Defense Index. The deal adds a popular, high-conviction thematic sector strategy to a global platform. More than $260 billion in index-based assets is tied to VettaFi.

Fixed-income investors are being paid more to take risk than they have been in years, but not all opportunities are created equal. Higher yield levels, heightened volatility and growing differences across countries, sectors, industries and issuers are expanding the opportunity set. Dispersion is the raw material from which active returns are generated. Below are four ways investors can capitalize on it.

AI could be a transformative force for the Fed’s policy framework. Elevated investment demand – now coupled with positive wealth effects that are necessitating tighter financial conditions – could eventually give way to a positive supply impact from higher productivity growth that could allow for easier financial conditions without inflationary implications.

Assessing the wall of worry. Here, we assess the market's growing wall of worry, explain why these worries warrant attention, and justify our continued constructive intermediate-to-long-term stock market outlook.

Economic data from last week continued to paint a picture of a robust U.S. economy with an accelerating pace of growth. After a strong durable goods report showed business fixed investment continuing to rise on the back of ongoing AI data center buildouts, the Atlanta Fed’s GDP Now estimate for third-quarter real economic growth remained at an elevated 5 percent.

From social media and AI tools to financial professionals and workplace resources, defined contribution (DC) plan participants are drawing retirement insights from an expanding portfolio of sources, according to our latest survey. But more content doesn’t necessarily mean better outcomes. We think plan sponsors are well positioned to help participants cut through the noise.

It’s a complicated economic environment to retire in, with high costs and significant geopolitical and policy uncertainty. Still, people want and often may need to retire. However, thanks to innovation in the asset management world, investors have an increasing array of options.

Before evaluating whether a long-short strategy belongs in a portfolio, we think it helps to understand what's actually happening under the hood. Let's start at the beginning.

The BlackRock Model Portfolio Solutions team made significant allocation shifts during the week ended September 24, 2026. The team recently managed over $300 billion and often causes shockwaves in the ETF industry.

The rise in Treasury yields has prompted a familiar set of explanations. Some investors have pointed to government borrowing and persistent inflation, while others have focused on the possibility that artificial intelligence will lift economic growth and interest rates.

Looking ahead, markets are priced for additional hikes. And our base case is that the FOMC will likely deliver one or two more 25-bp rate hikes through this year and into early next. However, looking further out, anticipating appropriate Fed policy through a financial-conditions-targeting framework has its own limitations. Hence, a neutral rate anchor is still useful.

LPL Research analyzes S&P 500 margin expansion, assessing how much is structural versus cyclical and what that means for future earnings forecasts.

Global growth remains resilient but uneven. In the United States, expansion is supported by private demand, a stable labor market and AI investment, while Europe and Japan continue to show surprising strength despite ongoing risks.

For many advisory firms, portfolio management creates a practical tension. Standardized models can simplify implementation and support scale, yet they may not reflect a firm's investment philosophy, tax realities, legacy holdings or preferred managers. Building every portfolio internally preserves control, but it also demands time, systems and ongoing investment oversight.

The week began with calls for a potential slowdown in AI spending amid growing safety concerns and included a midweek Fed rate hike for the first time since 2023. The S&P 500 finished slightly lower for the second week in a row despite continuing signs that economic growth is strong. Shorter-term bond yields pushed higher as investors priced in the potential for additional rate hikes, both in the U.S. and abroad.

Every runner has a natural pace: the speed that we maintain under optimal conditions like flat terrain, cool temperatures and a good night of sleep. Runners can train to speed up to meet a target time, or slow down for endurance.

A popular narrative for the rise in bond yields over the past few months is that the debt-funded AI capital expenditure cycle is crowding out the Treasury market. The crowding-out argument can appear compelling: AI companies are expected to continue to issue unprecedented amounts of debt at a time when Treasury supply remains elevated. Because both ultimately draw from the same pool of investor capital, yields must rise to clear the market.

The K-shaped economy is real, and it is old. What changed isn’t the shape of the economy; it’s just that the media found a narrative that gets lots of clicks and views, and we let headlines do our thinking for us.

Throughout this Indexing Redefined series, we explored how traditional market-capitalization indexing ties portfolio weights directly to stock prices, creating hidden concentration risks. Furthermore, we discussed how fundamental indexing offers a disciplined alternative by weighting companies according to their real-world economic footprint. In this final installment, we address the dilemma investors face in highly concentrated equity markets.

We are never going to get rid of the FOMC for political and practical reasons. For those of us who would like to see the market set rates without an FOMC intervening, this is as good as it’s going to get.

Open any market commentary today and the conversation is dominated by giants. Mega-cap technology companies command outsized shares of major indexes, and the private markets tell a similar story, as we watch companies increasingly staying private well past the point where they once would have gone public.

In an environment marked by the Fed’s first rate hike in three years and ongoing market uncertainty, income-focused investors face a unique dilemma. While cash alternatives offer attractive yields in the short-term horizon, they leave portfolios vulnerable to reinvestment risk should the

Municipal bonds might still offer attractive tax-advantaged income and relatively stable credit quality for investors who understand the risks.

Janus Henderson launched a new international equity ETF on Wednesday, according to a Janus Henderson press release. The Janus Henderson International Core Alpha ETF (JINT) seeks long-term growth of capital across developed markets outside the U.S.

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.

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.

On September 2, TMX VettaFi Head of Research Todd Rosenbluth appeared on the Schwab Network to discuss ETF inflows nearing record highs in 2026 and the 50th anniversary of the first-ever index fund, the Vanguard 500 Index Fund. The fund’s ETF share class, which trades under the ticker VOO, is a bit newer, having launched in 2010.

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).

Some investors are questioning how much further this year’s rally can run with the S&P 500 Index up 12.3% through the first eight months of the year. Encouragingly, history suggests that strong starts tend to persist; when the S&P 500 has gained more than 10% through August it has advanced from September through December in 25 of 28 instances, an 89% positive hit rate.

There is so much going on, it is hard to know where to begin. The data is all over the place. I had a long and epic dinner in New York with David Bahnsen, Rene Aninao, and Brian Syztel which has my mind buzzing with ideas and new concepts.

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.

In this article, Russ Koesterich argues that momentum remains supported by strong earnings growth, making the factor attractive despite market risks.

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.

Before I discuss why I disagree with the “AI bears,” I want to state that I respect their opinions, have evaluated their concerns, and have simply derived a different set of conclusions. That is an important statement, because this particular group of “AI bears” includes some of the sharpest risk minds in the business, and they have been early to almost every warning that later mattered.

My goal with this letter will be to not interrupt your long weekend too much. But there are some things that are happening that are important. My basic thesis for quite some time has been that we are in a Muddle Through Economy, which I’ve always meant that to me the GDP will grow slightly south of 2% over time.

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

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.

By enhancing the input that goes into so much of what we do—intelligence—AI’s potential to drive higher economic growth is enormous. But with fears of the technology's unintended consequences affecting the pace and depth of adoption, the promise of long-term gains must be set against more immediate risks.

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.

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.

In Part I of Indexing Redefined, the foundational strategies comprising Research Affiliates’ fundamental indexing methodology (RAFI) were introduced. With the baseline premise established, there is one myth to debunk: Some detractors may assume that RAFI is merely a niche value strategy.

For an asset often designated as a store of value, gold volatility has been especially apparent this year. After starting off the year with a high-paced record-setting run that lifted the metal to nearly $5,600 an ounce, including a 13% rally in January alone, momentum quickly faded as tensions with Iran ratcheted higher.

Markets are largely reducing expectations for a near-term U.S. Federal Reserve (Fed) rate hike, and we agree. July’s weak jobs report, the underwhelming retail sales report, and continued softening of the monthly inflation figures give the Fed room to stay patient in the coming months.

U.S. labor force participation is declining due to an aging population, slowing immigration, and other factors. This could impact economic growth and earnings moving forward.

Earnings have built a strong foundation. As we wrote earlier this month, earnings have provided a strong foundation for stocks this year. With second quarter earnings growth for the S&P 500 on track to exceed 30% (excluding private investment mark-ups) and analysts continuing to raise estimates, it's safe to say this season strengthened the fundamental case for equities.

European equities have long been written off as the ultimate value trap — a sleepy, slow-growth market living in the shadow of Wall Street’s tech-fueled mega-rally. But a massive shift in market dynamics is unfolding across the Atlantic.

Equity markets stumbled this week despite an economic backdrop that continues to show signs of broadening. While concerns about consumer strain are mounting, those worries have so far been offset by ongoing strength in business investment, particularly spending tied to artificial intelligence (AI).

U.S.-listed ETFs pulled in a record $193.42 billion in July, pushing year-to-date net inflows to $1.23 trillion. That total is the strongest seven-month haul on record, according to ETFGI’s July 2026 U.S. ETF industry report.

When it comes to equities exposure, investors typically gravitate toward a passive, market-cap-weighted index as the default strategy. These strategies are often billed as an efficient, low-cost method to capture broad market returns. As such, cap-weighted funds that track the S&P 500 or MSCI World have taken in trillions of dollars in global capital. However, within these market-cap-weighted indexes, a structural flaw exists.

GMO’s liquid alternatives are hedge fund strategies (e.g., equity long-short, global macro, event-driven) managed with an emphasis on risk control and liquidity. The GMO Alternative Allocation Strategy (“ALTA”) is a liquid alternative solution combining several underlying strategies; ALTA is available in a mutual fund with daily liquidity.

For years, Russell index reconstitutions have been treated as a routine maintenance event. Thousands of stocks are ranked, memberships are adjusted, and markets move on

High-yield municipal bonds are one of the best performing asset classes this year but that doesn't mean we think all investors should consider adding them to their portfolio.

Global business activity is showing signs of stabilization, but beneath the surface, the world economy remains divided. Growth momentum has improved in several major developed economies, led by a stronger U.S. expansion and a tentative recovery in parts of Europe.
