Since last report
split — not comparable
As of 15 September 2026, 31,544,237 Amphenol Corporation shares were held short — the total across every reporting firm, not one fund's position. The share count was restated by a stock split in this report, so it cannot be compared with the previous one — the filing carries a change figure, but it measures the split, not shorts being opened or covered. We leave that comparison out rather than tell you a story the data does not support. At the average daily volume of 11,480,110 shares, that position represents 2.75 days of trading — what the filing calls days to cover.
This is the most recent figure that exists, and it is 17 days old. FINRA collects short interest twice a month, on a settlement date, and publishes it about eight business days later. So nobody has a live short-interest number for APH — not us, and not anyone quoting one. We print the settlement date on the figure so you always know which day you are looking at.
We are not showing a longer trend for APH: a stock split inside this window restated the share count, and comparing figures across it would be comparing two different things.

- What is APH's short interest?
- 31,544,237 shares, as of the 15 September 2026 settlement date. That is the figure FINRA published, unadjusted.
- What percentage of the float is short?
- We do not publish that, because FINRA does not publish float. The regulator reports the number of shares held short; turning it into a percentage needs a share count from somewhere else, and different sources disagree about what counts as float. We would rather give you the number that was actually filed than a percentage built on an assumption.
- How current is this?
- It is 17 days old, and that is as fresh as short interest gets. FINRA measures it twice a month and publishes it seven business days after the settlement date. Any site showing you a "live" short interest figure is showing you something else.
- What does days to cover mean?
- It is the short position divided by average daily trading volume — here, 2.75. It describes how many days of ordinary trading the position is equivalent to. It is arithmetic from the filing, not a prediction about what will happen.
- Where does this come from?
- FINRA's consolidated short interest file, which is public. We read it directly and store it unchanged, except that we blank the days-to-cover placeholder FINRA writes when a stock has almost no volume.
