A share of the fund is the weight its issuer published, as of the Holdings filed date. Shares, preferred shares and debt are told by each fund\u2019s N-PORT asset type. A fund holding only the company\u2019s debt or preferred shares is listed under them, not counted as holding its shares. Options, swaps, futures and cash do not count as holding a company: a call option on a share is not the share. Funds whose book is gross exposure, not a portfolio, are left out.\n Each row shows the date the fund last filed.\n Look up another company .\n Questions people ask\n Which ETFs hold Aspen Aerogels Inc? 35 thematic and core ETFs hold Aspen Aerogels Inc, by holdings dated Jun 30, 2026 to Nov 4, 2026.
