What is happening

Recent company-specific developments and publisher coverage.

July 17, 2026William Blair Small-Mid Cap Growth Fund declined modestly, closing down about 1%, as a tech-led selloff weighed on growth-oriented small- and mid-cap equities. The Nasdaq fell sharply on the session amid a semiconductor-driven rout—triggered by TSMC's spending forecast and reports of China's new AI developments—which disproportionately pressured growth funds with tech exposure. Meanwhile, the broader financial services sector (XLF) held up relatively better, buoyed by a strong Q2 earnings season from major Wall Street banks, though Morningstar flagged ongoing concerns around AI disruption risks and private credit cracks as headwinds for the asset management industry.

July 15, 2026William Blair Small-Mid Cap Growth Fund (WSMDX) edged lower, dipping modestly as the broader financial services sector navigated a mixed backdrop. While large-cap financials surged on blowout Q2 earnings from Goldman Sachs, BlackRock, Morgan Stanley, and BNY — with record trading revenues and surging M&A fees — asset management sentiment faced headwinds from Morningstar's caution on AI disruption risks and cracks in private credit. Growth-oriented small- and mid-cap strategies also contended with elevated valuations, geopolitical uncertainty from renewed US-Iran tensions, and residual rotation away from higher-multiple growth names despite a softer-than-expected June CPI reading.

-0.8054

July 14, 2026William Blair Small-Mid Cap Growth Fund closed modestly lower as the broader financial services sector faced crosscurrents on July 14. A softer-than-expected June CPI print (3.5% headline) initially lifted equities, but lingering US-Iran tensions, rising oil prices, and renewed Fed rate hike concerns tempered gains for growth-oriented small- and mid-cap strategies. Morningstar noted financial stocks have lagged the broader market, citing AI disruption fears and cracks in private credit as headwinds for asset managers.

-0.6121

July 13, 2026William Blair Small-Mid Cap Growth Fund (WSMDX) declined notably as broad U.S. equities faced headwinds from renewed U.S.-Iran military strikes, which sent oil prices surging over 4% and stoked inflation concerns. The risk-off mood weighed particularly on growth-oriented small- and mid-cap holdings, with Nasdaq futures sliding ~1% amid a semiconductor selloff in Asia and investor caution ahead of a packed Q2 earnings season beginning with major banks on July 14.

-1.7937

July 9, 2026William Blair Small-Mid Cap Growth Fund (WSMDX) edged higher, outperforming the financial services sector as the XLF ETF held relatively flat in after-hours. The fund's small- and mid-cap growth focus benefited from a market narrative increasingly favorable to cyclical and growth-oriented smaller companies, with Edward Jones mid-year guidance noting that U.S. small- and mid-cap stocks claimed June's top performance spot. The broader backdrop remains complex—renewed U.S.-Iran military exchanges have reignited oil price and inflation concerns, while Q2 earnings season approaches with S&P 500 profits expected to rise ~24% year-over-year, setting a high bar for portfolio holdings.

0.905

July 8, 2026William Blair Small-Mid Cap Growth Fund (WSMDX) closed down 2.38%, pressured by a broad risk-off session as escalating U.S.-Iran tensions sent oil surging over 5% and rattled equity markets. A chip-driven tech selloff—sparked by disappointing Samsung semiconductor earnings—hit growth-oriented small- and mid-cap names particularly hard, while rising Treasury yields and geopolitical uncertainty dampened appetite for higher-risk, growth-focused funds. The financial sector ETF (XLF) also pulled back amid the macro turbulence, reflecting broad defensive positioning as investors awaited Fed minutes and monitored the fragile Middle East situation.

-2.3847

July 2, 2026William Blair Small-Mid Cap Growth Fund (WSMDX) declined nearly 2% as broader market headwinds weighed on small- and mid-cap growth equities. Chip stocks led the selloff after reports that Meta is building a cloud business to monetize excess AI computing capacity, raising concerns about future semiconductor demand. Meanwhile, investors remain cautious ahead of the June nonfarm payrolls report, with softer-than-expected private payrolls data fueling uncertainty around Fed rate policy — a particularly significant overhang for growth-oriented funds sensitive to interest rate expectations.

-1.8945

June 29, 2026William Blair Small-Mid Cap Growth Fund edged up modestly, touching a new 52-week high, as broader market sentiment improved on reports that the U.S. and Iran agreed to halt tit-for-tat strikes in the Strait of Hormuz, easing geopolitical risk that had rattled equities the prior week. The backdrop for small- and mid-cap growth stocks has grown more constructive as AI sentiment softness and tech mega-cap weakness—Nasdaq fell 4.5% last week—has spurred a rotation toward broader market segments, with analysts noting that 'money is being liberated to shift into more neglected areas.' William Blair's own market commentary highlighted resilient equities supported by strong earnings and business investment, even as rising bond yields and persistent inflation keep the macro picture mixed.
