FormFactor Inc. shares fell roughly 6.0% in mid-day trading, touching $119.02, as a broader semiconductor downturn that started in the prior session carried over. The pullback swept through chip-adjacent stocks after a steep decline at Broadcom set the tone for renewed risk-off sentiment in the group.
The rout was precipitated when Broadcom dropped more than 12% on heavy volume following its fiscal second-quarter results. Investors had been hoping for an upward revision to the company’s 2026 AI semiconductor sales outlook, but Broadcom left that sales forecast unchanged. The lack of a raised target - rather than an explicit negative update - disappointed market participants who had expected AI-related demand to lift the company’s guidance.
While market forces dominated the day, there were company-specific developments for FormFactor that offered a mixed picture. On June 4, 2026, Evercore ISI upgraded FormFactor to Outperform from In Line and set a $155 price target. The firm based that target on a 38x projected 2028 EPS multiple and pointed to AI-driven upside and an anticipated 41% two-year compound annual growth rate in the company’s EPOS business as reasons to support a richer valuation.
Despite that upgrade and FormFactor’s strong first-quarter 2026 results, the positive news could not overcome the broader selloff. The stock’s valuation remained sensitive after a powerful rally in the prior year - the shares have climbed about 293% over the last 12 months - and an insider sale added a modest further headwind. Director Sheri Rhodes disposed of roughly $793,531 worth of FormFactor stock on June 2, 2026, a transaction that reinforced investor concerns about current valuation levels.
Sector indicators reflected the breadth of the weakness. The Philadelphia Semiconductor Index fell by more than 6% during trading, mirroring the steep moves at several large-cap chip names. Broadcom’s downbeat market reaction on June 5 rippled through the industry and weighed particularly heavily on higher-multiple growth-oriented semiconductor names.
At the same time, macroeconomic data compounded pressure on richly valued growth stocks. U.S. non-farm payrolls for May came in at 172,000, well above forecasts of 85,000. The stronger-than-expected jobs print increased speculative pressure that the Federal Reserve could move to tighten policy further, driving up bond yields. Higher yields and a more hawkish macro read tend to hurt long-duration, high-multiple equities, a dynamic that contributed to the selling in FormFactor and peers.
In short, the day’s decline in FormFactor shares reflected a convergence of factors: sector contagion after Broadcom’s guidance disappointed investors’ AI-driven expectations, a firmer economic data set that raised interest-rate concerns, and ongoing valuation sensitivity for a stock that has already posted a substantial rally. Even with favorable company metrics such as strong Q1 2026 results and a recent analyst upgrade, FormFactor was not immune to the broader reassessment of semiconductor valuations.
Contextual takeaway
- Broadcom’s unchanged 2026 AI semiconductor sales forecast was the proximate trigger for the sector-wide decline.
- Stronger-than-expected May U.S. non-farm payrolls heightened rate-hike speculation and pushed bond yields higher, pressuring high-multiple growth names.
- Company-specific positives for FormFactor, including an Evercore ISI upgrade and solid Q1 2026 results, were insufficient to offset market-wide selling and valuation concerns.
