Aspen Aerogels Stock Slides -58% With A 7-Day Losing Spree
Aspen Aerogels (ASPN) stock hit day 7 of a continuous streak of days with losses, with cumulative losses over this period amounting to a -58% return. The company has lost about $357 Mil in value over the last 7 days, with its current market capitalization at about $254 Mil. The stock remains 74.1% below its value at the end of 2024. This compares with year-to-date returns of 14.5% for the S&P 500.
Aspen Aerogels’ recent streak reflects a brutal EV market reset, as Q3 earnings missed estimates and full-year guidance plunged to $270-280M amid significant impairment charges. This sparked sharp analyst downgrades, highlighting investor jitters over the company’s critical EV segment.
What is the point? Sustained weakness can be more than noise. It often signals shifting sentiment or deeper concerns. A multi-day losing streak may warn of further downside, or present an opportunity to buy if fundamentals are intact. Our take: There are several things to fear in ASPN stock given its overall Weak operating performance and financial condition. In addition, keeping in mind its High valuation, we think that the stock is Unattractive (see Buy or Sell ASPN). Nevertheless, smart investing isn’t about stock picking or prediction, it’s about asset allocation. See how Trefis’ Boston-based, wealth management partner does it. It has included High Quality Portfolio as part of its asset allocation strategy.
