A quiet period is a time during which a company, its insiders or its underwriters restrict public statements about the company. The term covers two different things: the securities law limits around an offering such as an [IPO](https://www.quantisnow.com/glossary/ipo), and the voluntary blackout many public companies observe before reporting earnings.

## How it works

**Around an IPO.** Securities laws restrict "gun-jumping," meaning communications that could hype a stock before and during a registered offering. From the period before filing through the offering, companies generally avoid new promotional statements outside the prospectus. After the IPO, research analysts at participating [underwriters](https://www.quantisnow.com/glossary/underwriter) are restricted from publishing for a set period under FINRA rules. In practice, a wave of coverage initiations from the underwriting banks commonly arrives around 25 days after the IPO, an event often called the end of the quiet period.

**Before earnings.** Many companies stop meeting with analysts and investors and avoid commenting on results in the weeks before a quarter's numbers are released. This is company policy, not an SEC rule, and helps avoid selective disclosure under [Regulation FD](https://www.quantisnow.com/glossary/regulation-fd).

## Why it matters for traders

The end of the IPO research quiet period is a known catalyst. Underwriting banks typically [initiate coverage](https://www.quantisnow.com/glossary/initiation-of-coverage) with mostly positive ratings, and the stock can move on the cluster of reports. Traders also map it alongside other post-IPO dates: the first earnings report and the [lock-up expiration](https://www.quantisnow.com/glossary/lock-up-period). An earnings quiet period means management silence is not a signal; it is routine.

## Example

Hypothetical Northwind Cloud (NWCL) prices its IPO at $22 on March 3. On the 25th day after the IPO, five underwriting banks initiate coverage: four at buy with price targets between $32 and $38, and one at hold with a $27 target. The stock, which had drifted to $26, rises 6% that day.

## FAQ

### How long is the IPO quiet period?

The post-IPO research blackout varies with the offering and the firm, but coverage from the underwriters commonly begins around 25 days after the IPO.

### Can a company talk during an earnings quiet period?

It can, but most choose not to discuss results or guidance until they report, to avoid selective disclosure.
