Filings SEC · Quote Yahoo cited a paper published in Diabetes Care in its regulatory filing with the U.S. Securities and Exchange CommissionU.S. Securities and Exchange Commission
Regulator · Website. The company read the way it wrote the paper and the actual scope of the paper in order. It described where the stock price movement over the following month compared to past similar cases. This is a hindsight judgment written after knowing the results. The paper was read only up to the abstract.
The disclosure is written in the press release as follows:
A spontaneous report submitted to the U.S. Securities and Exchange Commission when a listed company has something to inform shareholders is called 8-K. The item number of the document filed by Xeris Biopharma on 2025-06-03 was 7.01 Reg FD Disclosure · 9.01 Financial Statements and Exhibits. The company cited a paper published in Diabetes Care in the press release attached to it. If the sentence citing the paper is translated verbatim, it reads as follows.
Diabetes Care 2025; dc242841. https://doi.org/10.2337/dc24-2841 14. Recorlev [prescribing information].
The reader should first check where the company placed the paper in the press release. Next, they should determine whether the paper supports the company's entire claim or only a part of it. To answer the latter question, one must read the full paper. This article, which only read the abstract, cannot provide an answer.
The scope of the paper discussed in the abstract is limited to this.
The paper's title is Prevalence of Hypercortisolism in Difficult-to-Control Type 2 Diabetes and it was published in Diabetes Care on 2025-04-18. The authors are affiliated with University of North Carolina at Chapel Hill · University of Washington · VA Puget Sound Health Care System · Brigham and Women's Hospital. The summary at the beginning of the paper is called abstract. This article only read up to that point. The paragraph was written by a person after filtering out a draft written by a machine by comparing numbers, so it is of a different grade than a full reading of the paper.
This is a prospective observational study examining how common excessive cortisol production is among type 2 diabetes patients whose blood sugar remains uncontrolled despite using multiple medications. Dexamethasone suppression tests were conducted on individuals with high glycated hemoglobin and those using two or more blood sugar medications, excluding common causes of false positives. The primary outcome was the proportion of individuals diagnosed with this condition. Since it is an observational study, this paper does not address whether treating this condition would control blood sugar.
What the abstract does not answer remains in the full paper and its appendices. This article, which did not go beyond the abstract, leaves the blanks as they are. Readers should compare the two citations above to determine which sentence in the abstract corresponds to the excerpt cited by the company.
One month later, the stock price was within the middle half of the sample.
The remaining return after subtracting the portion that moves with the overall market is called excess return. The date is written as trading day, counting only the days the stock market is open. In terms of the calendar, 20 trading days are about a month. The excess return for the day of the regulatory filing and the following month are listed in the table below.
| Period | Excess return relative to the market | Meaning |
|---|---|---|
| Five trading days before the filing | +2.8% | The extent of movement before the filing |
| On the day of the filing | −9.3% | On the filing day or the first trading day after |
| Accumulated over +1 to +5 trading days | −14.3% | One week |
| +1~+20 trading day cumulative | −4.1% | One month |
A bundle of past cases of the same type is called a sample. The position counted from the bottom is expressed as a percentile. The one-month excess return of −4.1% in this case is within the bottom 57% of the 142 cases in the sample, placing it in the lower half.
| Sample scale (20 trading days) | Tenth from the bottom | Fourth from the bottom | median | top 25% | top 10% | This case |
|---|---|---|---|---|---|---|
| Excess return | −31.9% | −20.1% | −7.4% | +5.5% | +19.5% | −4.1% |
Half of the sample falls between the two marks in the middle of the table. One checks from the table whether this case is inside or outside. The sample collects cases where U.S. listed companies wrote papers in 8-K over the past ten years. The company itself is excluded from the sample. The numbers written here are past facts, not rules to be applied to the next case.
After the disclosure, the company issued such documents
After the disclosure date, the company issued three 8-K filings. Only the item numbers are listed. In 8-K filings without titles, the item number indicates the type of content. One can determine whether it was an earnings announcement or a contract based on that number. What exactly happened is read in the original text of each link.
