The short answer
Orin Hirschman filed a Schedule 13G on Oct 19, 2026, reporting 7,150,126 shares, or 8.6% of the class of Aspen Aerogels (ASPN). The filing came 55 days after the company’s Aug 6, 2026 results announcement. It reports ownership, not when shares were bought, and does not explain the share-price moves recorded around the filing date.
What did Orin Hirschman report?
The SEC Schedule 13G filed by Orin Hirschman on Oct 19, 2026 reports 7,150,126 shares, 8.6% of the class of Aspen Aerogels (ASPN).
A Schedule 13G is an ownership filing. The information in the pack does not identify when shares were bought.
When was the filing made?
The filing was made 55 days after Aspen Aerogels announced results on Aug 6, 2026. The results announcement was reported on an 8-K Item 2.02.
The timing places the filing after that announcement, but does not establish a connection between the results and the reported ownership.
What other ownership and short-interest records are available?
FINRA short interest for ASPN on the settlement date of Sep 30, 2026 was 6,101,632 shares, down −32.69% on the previous report, and about 5.24 days of average volume.
In 13F filings for the quarter ended Jun 30, 2026, the largest positions that grew included Jacobs Levy Equity Management, Inc, which increased its position to 839,304 shares, and Royce & Associates LP, which increased its position to 336,705 shares. Cannell & Spears LLC was the largest position that shrank and sold out.
A 13F is a quarter-end snapshot with no trade date. These records do not establish when those reported positions changed.
What coverage and share-price context was recorded?
Finnhub listed the headline “What Aspen Aerogels Bears Saw Before The Fall” from Yahoo, Oct 19, 2026, and “Aspen Aerogels Q2 2026 Earnings Call Transcript” from Benzinga, Oct 6, 2026. OQRO has not checked the headlines and does not summarize the articles.
ASPN closed at $5.48 on Sep 30, 2026, the last session on or before the filing date. From Aug 31, 2026 to Sep 30, 2026, the close moved from $4.93 to $5.48, a change of +11.2%. From Sep 30, 2026 to Oct 19, 2026, the close moved from $5.48 to $5.32, a change of −2.9%. More company context is available on Aspen Aerogels on OQRO.
What this does not tell you?
A Schedule 13D or 13G is an ownership filing, not a trade; it does not say when shares were bought. The filing does not explain the share-price moves, and other news can move a price.
Press headlines are listed as published by the outlets; OQRO has not checked them and does not summarize the articles. Share-price moves are included as context only. This describes public filings and is not investment advice.
