Substantial doubt about the company's ability to continue as a going concern.
“The Company's liquidity condition raises substantial doubt about the Company's ability to continue as a going concern for one year from issuance of these unaudited condensed financial statements.”
Institutional ownership from SEC Form 13F filings. Investment managers with more than $100 million in U.S. equities must disclose their positions every quarter, within 45 days of quarter-end, so the holdings shown can lag the market by up to a quarter.
The Sep 30, 2026 filing window is
still open — showing the latest known positions. Funds that have not filed yet
carry their prior-quarter positions; a fund that filed without this stock counts
as sold out. Each fund's Change is measured against its own
previous reported quarter, shown in the Reported column. Pick a
completed quarter in the Quarter selector below to put every
fund on one quarter and see the stock-wide activity breakdown.

Each kind of 13F filer's share of the common shares 13F filers report. Holder type comes from regulatory
records, never the filer's name; style, turnover and horizon are measured from each filer's own 13F book.

The Sep 30, 2026 filing window is still open, so its
bar carries the Jun 30, 2026 positions of filers that have not filed yet.
How the mix is measured
Shares are 13F common shares restated to today's split basis; options and principal amounts are left out.
The change compares only filers with a 13F in both quarters and keeps each filer in its bucket of the later
quarter on both sides; a filer that continues under a new CIK is compared through its successor. Holder type
comes from each filer's current regulatory profile; client base and private funds come from the Form ADV roster
current at each quarter end (rosters from December 2019, so an earlier quarter reads Unknown). Style, turnover, horizon and
book size are measured from each filer's 13F book in the newest measured quarter, and Not measured means none
was. Actively managed books are those measured systematic-like, concentrated or diversified active.
Conviction and Crowding
35 13F filers, quarter ended Jun 30, 2026
Measured across every 13F filer's common-share book once the quarter's filing window closed. Crowding counts
filers with high turnover or that advise private funds on Form ADV.

How fund types are measured
Each fund series counts once, with its latest Form N-PORT report dated inside the quarter; only long share
positions count, restated to today's split basis. The fund type is the series' latest Form N-CEN answer on or
before the quarter end (the index-fund box and the exchange-traded flag), never its name. Unclassified funds have
no usable N-CEN; unit investment trusts are among them, so index ownership is a floor. Funds sit inside their
advisers' 13F reports, so these shares overlap the 13F figures and are never added to them.
