About Co-Diagnostics – Medical Devices

Co-Diagnostics, Inc. makes tests that can detect diseases by analyzing DNA and RNA, which are the genetic building blocks found in humans, animals, plants, and germs. The company makes money by developing and selling these tests, known as PCR tests, around the world.

Co-Diagnostics is known for making tests for diseases such as COVID-19, tuberculosis, and hepatitis. PCR is a method that copies small pieces of genetic material many times over, making it easier to detect diseases or specific traits, even in very small samples.

The company also offers tests that can identify genetic traits in plants and animals. This can be useful, for example, for farmers or breeders who want to check for certain characteristics.

In addition, Co-Diagnostics is developing a small, portable PCR device. The goal is to make testing possible outside of laboratories, including in patients' homes, rather than requiring a hospital or lab visit.

Co-Diagnostics was founded in 2013. The company operates in the United States and internationally. It plans to soon start selling diagnostic equipment made by other companies as well, offered together as complete, ready-to-use laboratory solutions.

What does the trend tell you?
Short interest is falling. It is down 1.5 percentage points over the last month and now stands at 4.4%. The peak was 9.8% on Jun 11, 2026, so it is now 5.4 percentage points lower. This is how shorting works: whoever shorts has borrowed the share and sold it, and to close the position again they must buy the share back. Falling short interest therefore means shares are being bought back in Co-Diagnostics right now.

Many investors watch for exactly this: short interest that has been high and starts falling back. The professionals who bet on a falling price are closing down. That is not in itself a signal about what the price will do — we cannot predict the market, and short interest is only one number among many. But it does say something about what the large players are doing.
The stock has a moderate share of short selling. Between 2-5% of the freely traded shares are sold short, which is within the normal range for most stocks.

Short interest comes from our data provider EODHD. The figure is reported about twice a month; we check it every trading day.
