(Reuters) -Shares of U.S. medical device makers rose on Monday as a potential hit from the cardiac benefits of Novo Nordisk (NYSE:)’s weight-loss drug Wegovy was seen as more moderate for the battered sector than initially feared by investors.

To be sure, the full results presented on Saturday at a major medical meeting gave analysts even more confidence in the heart protective benefits of the hugely popular drug.

“We believe key findings could be seen as a marginal positive for some, but not all, verticals within MedTech, especially given currently depressed sentiment,” said Baird analyst Jeff Johnson.

The data, for instance, showed the reduction in risk of non-fatal stroke was not statistically significant over the length of the trial.

That lifted shares of Penumbra (NYSE:), which makes devices used in surgeries for stroke patients, 13% in morning trading.

Its shares have tumbled about 28% as of last close since Novo in August said Wegovy had also shown a clear cardiovascular benefit.

The $4.64 billion iShares US Medical Devices ETF rose 2.3% on Monday, eyeing its biggest one-day percentage gain since April. The ETF is down about 13% this year, through Friday’s close.

Shares of diabetes care device makers Abbott Laboratories (NYSE:), Dexcom (NASDAQ:), Insulet (NASDAQ:), Tandem and Medtronic (NYSE:) gained between 2% and 8%.

Monday’s moves are the latest sign that investors across industries are closely looking at developments with the popular new class of weight-loss and diabetes drugs called GLP-1s such as Wegovy and Eli Lilly (NYSE:)’s Mounjaro and Zepbound.

“The full detailed results … do not shift our outlook that MedTech device stocks appear broadly oversold,” said Leerink analyst Mike Kratky.
