1) We are short Jin Medical International Ltd $ZJYL, a China Hustle-style charade. Jin sells wheelchairs and parts in China. In 2022, its revenues fell 8% to just $19M. $ZJYL trades at ~45x revenues. At reasonable "peer" levels of 1-6x sales, $ZJYL shares fall 90% or more.
2) $ZJYL went public in March 2023, underwritten by China-focused chop shop, Prime Number Capital. Prime Number is headquartered in a Long Beach home and has already been sued by investors at least twice for alleged roles in other China frauds. Their track record is horrific.
3) In Sept 2023, $ZJYL faced a NASDAQ delisting notice as it fell under the 300 shareholder threshold required for continued listing. On October 24, $ZJYL CEO Erqi Wang filed a Form 144 to sell 545,893 shares. Then $ZJYL fired its auditor, MarcumAsia, and hired DNTW Toronto.
4) Current $ZJYL auditor DNTW appears to have been previously shut down and its partners charged by the SEC for its role in another China fraud, Subaye, which claimed to be running a cloud business that didn't exist. We think the $ZJYL story will end similarly...
5) We think $ZJYL's recent announcements coinciding with the stock's 10x rise are likely conjured up solely to pump shares and avoid pending delisting. We uncovered that each of Jin's December 11 and December 14 "deals" are with related parties - namely CEO Erqi Wang himself.
6) On December 11, $ZJYL claimed it won a 66M RMB ($9M USD) order to sell oxygen chambers to "Conlo Industrial Development." However, Conlo's records show that Conlo is majority-owned by $ZJYL CEO Wang, while records also name $ZJYL CFO Ziqiang Wang and an $ZJYL email address.
7) Similarly, on December 14, $ZJYL claimed to enter an MOU to acquire all or a part of Juangsu Zhongjin Kanglu Information Tech Co. ("Kanglu"). Yet again, Kanglu is controlled by $ZJYL CEO Erqi Wang, and Kanglu owes $4.8M to $ZJYL. In this light, the "MOU" looks like a bailout.
8) $ZJYL hasn't filed results since 3/31 and reported material weaknesses in each 2020, 2021, and 2022. $ZJYL makes related party loans to its CEO Erqi Wang and guarantees loans to Wang's outside entities. To us, $ZJYL's public listing looks like an insider enrichment scheme.
9) On December 26, $ZYJL disclosed that its audit committee chair, Jing Chen, resigned. Chen's resignation is especially concerning given Chen previously served numerous other China frauds. $ZJYL must be especially spoiled if Chen can no longer stand the stench.
10) $ZJYL cleverly reassured investors that Chen's resignation was not due to "disagreement with the Company's accounting policies," but $ZJYL has yet to file financials since the bogus deals, and the notice excludes standard language covering general business disagreements.
11/11) $ZJYL has an appeal hearing set with the NASDAQ for March 14 to stave off delisting. We see no reason that $ZJYL ought to continue trading. We think that NASDAQ and the SEC ought to halt shares to protect investors from yet another obvious China-based con. @NasdaqExchange @Nasdaq

NEW: We are short Nvidia $NVDA. We believe Nvidia has a significant China problem. Please see our full report and disclosures now available on our website, link in bio.
2) $NVDA claims its China business went to "zero" after April 2025 U.S. trade restrictions. We believe that in reality, over 20% of Nvidia's FY 2026 compute revenues remained driven by China via illegal GPU diversion and Southeast Asian intermediaries.
3) $NVDA vouches for Megaspeed - its largest SEA chip buyer, under U.S. and Singapore investigation - as having no Chinese ownership and free of diversion concerns. We uncovered documents, however, that suggest Megaspeed was financed by Alibaba through a Singapore shell company.
NEW: We are short ADMA Biologics $ADMA. We believe the ASCENIV growth story is in reality a story of channel stuffing and an undisclosed related party distributor. Real revenues declined 3% in 2025 vs. 20% reported growth. It's already over. Full report available on our website.
2) $ADMA recognizes revenues upon delivery to distributors, who then sell onto end customers (infusion clinics, pharmacies, healthcare providers) and ultimately patients. In 2025, two $ADMA distributors drove 73% of revenues and represented 87% of receivables at year-end.
3) $ADMA generates 75%+ of revenues from ASCENIV, a 10% IVIG priced at 6-10x standard IVIGs despite carrying a standard PI label. As such, payors put up prior auths, step therapy, and outright denials. When providers don't get paid, they stop ordering from distributors.
NEW: We are short Ether $ETH, and ETH-linked securities, incl. $BMNR.
We think ETH tokenomics are impaired following the December 2025 Fusaka upgrade. Vitalik knows it and is selling, while $ETH's most ardent bull, Tom Lee, is throwing good money after bad.
$ETH is going lower.
2) Tom Lee's $BMNR defends $ETH by claiming "ETH is not in a death spiral because utility is going up." Lee cites post-Fusaka spikes in $ETH active address and transaction counts as evidence of supposed "strengthening fundamentals" and institutional adoption. Lee is clueless.
3) By Lee's own logic, if $ETH activity does NOT reflect increased utility and strengthening fundamentals, then $ETH would be in a death spiral.
Our research says this is exactly what's happening.

We are again short Archer Aviation $ACHR. We have not commented publicly on Archer for some time, but we believe the Company continues to mislead investors, and may also now have Reg FD problems… We have 3 simple questions for CEO Goldstein.
2) On $ACHR's November 6, 2025 conf. call, CTO Muniz said "our first TIA campaign with the FAA…could happen as soon as the end of this year." CEO Goldstein said "we're now nearing completion of the piloted CTOL flight regime" and that piloted VTOL testing would be next.
3) Yet flight logs suggest $ACHR has not engaged in a single ground or air test for the past 3 months. Further, $ACHR doesn't appear to have obtained an airworthiness certificate for N704AX - they couldn't fly it even if they wanted to.
NEW: We are short T1 Energy $TE: The “American Made” Charade Masking Chinese Supply and Control Built to Reap 45X Credits and Evade Tariffs at U.S. Taxpayers’ Expense.
Days ago, T1 was sued by RWE Clean Energy – its largest independent offtake customer and the group that CEO Barcelo previously called, “the focus of our commercial strategy.” RWE cancelled its offtake agreement on December 19, 2025. T1 has not publicly disclosed either the cancellation or the lawsuit to our knowledge.
RWE alleges that $TE lied about the existence of other non-Trina customers, failed to provide audit reports of module raw material and conversion costs, failed to deliver modules meeting the agreed-upon specifications, and breached confidentiality.
1) We are short Praxis Precision Medicines $PRAX: Mined the Gap - How PRAX Twisted Dropouts into a Phase 3 “Win” with Make-Believe Data and Half-Baked Analysis. Our full report is now available at our website, culperresearch.com
2) One month ago, $PRAX touted "positive" Phase 3 results for ulixacaltamide ("ulixa") in essential tremor. Shares rallied 185%. We think $PRAX gamed the readout via a last-minute unapproved endpoint change, imputation of make-believe data, and half-baked tipping point analysis.
3) $PRAX bought ulixa for just $1M in 2018. The Company then ran a Phase 2 trial for ulixa in ET, which failed (p=0.126). $PRAX pushed onto a Phase 3 anyway. Three other drugs with ulixa's MoA have also failed early trials in ET - the drug repeatedly shows no efficacy.
