What is the market telling us
PubMatic’s shares are very volatile and have had 24 moves greater than 5% over the last year. But moves this big are rare even for PubMatic and indicate this news significantly impacted the market’s perception of the business.
The previous big move we wrote about was 27 days ago when the stock dropped 2.7% on the news that the major indices pulled back as the Bureau of Labor Statistics reported a hotter-than-expected September inflation print, pushing Treasury yields higher.
The consumer price index rose 3.7% year-over-year in September, topping the 3.6% estimate from economists polled by Dow Jones. Core inflation, which excludes volatile food and energy costs, climbed 2.6% annually against expectations of 2.5%. Following the print, the 10-year Treasury yield climbed over six basis points to 5.278%, while the 30-year yield advanced past 5.59%, per CNBC market data. Rising yields intensify pressure on equity valuations as third-quarter corporate earnings get underway.
In remarks carried by CNBC, Franklin Templeton Institute head investment strategist Jeff Schulze noted that pressure across the long end of the curve acts as a valuation headwind for risk assets. Higher benchmark yields mechanically elevate the discount rate applied to corporate earnings, compressing the multiples investors are willing to pay for equities. When sticky inflation dampens expectations for monetary easing, the repricing falls heaviest on high-multiple growth sectors whose projected cash flows sit furthest in the future.
PubMatic is up 99% since the beginning of the year, but at $17.10 per share, it is still trading 10.9% below its 52-week high of $19.18 from September 2026. Despite the year-to-date gain, investors who bought $1,000 worth of PubMatic’s shares 5 years ago would now be looking at only $488.01.
