    Listen to the news

    Inspire Medical Systems (INSP) just delivered a quarterly update that combined weaker sales, a swing to losses, and narrowed full year guidance, which has put fresh focus on the stock’s risk profile.

    Despite the earnings setback, the share price of Inspire Medical Systems has already been under pressure, with the stock down 30.66% on a year-to-date basis and the 1-year total shareholder return declining 21.78%, while the 3-year and 5-year total shareholder returns have fallen 49.10% and 77.08% respectively. The 7.13% 90-day share price gain had hinted at a short burst of renewed optimism, but the recent 1-day and 7-day share price returns of down 3.83% and down 6.05% suggest momentum has cooled as investors reassess growth prospects and risk after the latest guidance.
