Schwab’s chief investment strategist urged advisors to pair optimism with discipline, warning that speculation, data gaps, and overreliance on megacaps could test investors’ resolve in a K-shaped economy.

Optimism must coexist with caution. Optimism is the prevailing sentiment at the Schwab IMPACT 2025 conference — markets have held up, investors are engaged, and the conversation around innovation and AI persists. But for Liz Ann Sonders, Schwab’s chief investment strategist, there must be a balance between the two forces. Sonders unpacked the complex crosscurrents defining today’s economy with InvestmentNews during the conference. 

The K-Shaped Reality


Sonders describes today’s economy as one of extremes, what is known as a "K-shaped" recovery. “K-shape is a way to think about all the bifurcations that exist in the economy and in the market,” she said. “From upper-income consumers versus lower-income, asset owners versus non-owners, AI-related versus non-AI industries — there are wide spreads everywhere.”

That unevenness extends to markets, where the so-called “Magnificent Seven” dominate the indexes. “It’s great when those stocks are doing well,” Sonders said, “but if you allow your portfolio to get overly concentrated, it’s more painful when the inevitable pullback comes.”

She pointed out that while Nvidia, for example, has been the top contributor to S&P 500 gains, it actually ranks 40th in price performance this year. “People underestimate the multiplier effect of size,” she said. “There are plenty of opportunities outside the big names.” Her message to investors: keep in mind cap size multipliers when measuring portfolio performance, and there are "plenty of opportunities to do well, other than massively concentrating" in the Mag Seven.

Dancing in the dark
 

When Sonders refers to investors “dancing in the dark,” it’s not just a nod to Bruce Springsteen. It’s her metaphor for an era of imperfect information. “We’re in a data desert right now,” she said, citing government shutdowns, low survey response rates, and political tensions undermining confidence in official statistics.

Even when federal data flows again, Sonders expects investors to rely more heavily on private sources such as the ADP payroll reports, PMI surveys, and Federal Reserve regional outlooks. “I think you’re going to see more parallel analysis — a check and balance against government-issued data,” she said. She agrees with the phrase canonized by statistician George Box that “all models are wrong, but some are useful.”

Under-appreciated risk
 

Asked about the biggest under-appreciated macro risk, Sonders pointed to market speculation, drawing the distinction between investing and gambling. “There’s too much of a gambling mentality that’s become pervasive — in markets and in culture,” she said. “We’re certainly trying to reinforce that gambling and investing are not the same.”

That mindset, she added, often emerges late in market cycles. “Those periods of extreme speculation and froth eventually don’t [last] very long,” she said. “We may see some pain inflicted on retail traders who are just going out into this world without a plan.”

For Sonders, discipline still trumps timing. “Neither ‘get in’ nor ‘get out’ is an investing strategy,” she said. “Diversification and periodic rebalancing may not sound exciting, but that’s how you ride through extremes.”

Promise and peril of AI
 

Few topics stir as much debate today as artificial intelligence. Sonders recently co-authored a report weighing its duality — “not a bull versus bear case,” she said, “but the balance between the enthusiasts and the skeptics.”

While she acknowledges the risk of “circular financing” and speculation reminiscent of the late 1990s, she sees legitimate promise in AI’s capacity to boost productivity and margins. “The companies that turn away from AI are more at risk than those that bring it into their business,” she said. “AI won’t replace creativity, context, culture, or community — and that’s what humans still bring.”

Sonders believes the next few years will reveal which companies truly harness AI rather than just market it. “We’re finally starting to see real use cases — that’s where my enthusiasm lies,” she said.

Market resilience
 

Despite the noise, Sonders sees the market as resilient — though appearances can be deceiving. “An index like the S&P 500 looks healthy because it’s cap-weighted and dominated by the megacaps,” she said. “But the fuller story is told under the surface, where there’s been churn, rotation, and weakness.”

Looking ahead, she’s watching inflation closely. “A meaningful move back up in inflation — or even inflation staying sticky above target — could put the Fed in a pickle,” she said. “A stagflationary backdrop would make it hard to balance the dual mandate.”

Still, her advice to investors remains steady: “It’s not what we know that matters — it’s what we do along the way that matters.”

In other words, even in a bifurcated economy, an imperfect data landscape, and a speculative market, discipline — not darkness — will ultimately guide investors through.
