What is an active market?

Explanation of an active market

The concept matters mainly in financial reporting, where it determines how readily an asset or liability can be measured at fair value. When a market is active, recent transaction prices reflect what buyers and sellers are actually willing to exchange, so those prices can be used with little adjustment.

Active markets are central to the fair value framework in UK-adopted international accounting standards and in FRS 102. Under this framework, a quoted price in an active market for an identical item gives the most reliable evidence of fair value and sits at the top of the fair value hierarchy. Preparers of statutory accounts, auditors and valuers all rely on this distinction.

Whether a market is active is a matter of judgement based on observable activity, not on the type of asset alone. The same instrument may trade in an active market during normal conditions and in a less active one when trading falls away.

Key characteristics of an active market

Key characteristics of an active market include:

• Transactions occur frequently enough for prices to be observed on a continuing basis.
• Trading volume is high enough for individual deals to reflect genuine market conditions.
• Price information is publicly available and updated close to real time.
• The items traded are homogeneous, so quoted prices relate to identical or near-identical assets or liabilities.
• Willing buyers and sellers can normally be found at any point during trading.

How an active market works

Activity is assessed by looking at how often and how much of an asset or liability changes hands, and whether that trading produces prices that are current and accessible. A recognised stock exchange for widely held shares is a common example, because many buyers and sellers transact throughout each trading day.

When these conditions hold, an observed quoted price can be taken as fair value without significant adjustment. When frequency or volume falls, the market may become inactive, and prices from the few transactions that occur may no longer represent orderly dealings. In that situation, valuation techniques and other inputs are used instead of a direct quoted price. The classification is therefore dynamic and depends on conditions at the measurement date.

Example of an active market in practice

Ordinary shares in a large company listed on the London Stock Exchange trade many times each day between numerous participants, with prices published continuously. This is an active market, so the closing quoted price gives a direct measure of fair value. By contrast, shares in a small unlisted company that changes hands only rarely would not meet the frequency and volume conditions, and its value would need to be estimated using a valuation technique.

Common misconceptions about an active market

An active market does not mean prices are high or rising. It describes the level of trading activity, not the direction of value.

An active market is not the same as a market with a single large transaction. Frequency and volume both matter, so one significant deal does not make a market active.

A fall in trading does not automatically make a market inactive. The assessment depends on whether current pricing information remains available at the measurement date.

Questions about active markets

What is the difference between an active market and an inactive market?

An active market produces frequent, high-volume transactions and current, accessible prices. An inactive market shows a significant fall in trading activity, so recent prices may be scarce or unrepresentative and fair value usually has to be estimated using a valuation technique.

How does an active market affect fair value measurement?

A quoted price in an active market for an identical asset or liability is treated as the most reliable evidence of fair value and ranks highest in the fair value hierarchy. It can generally be used without adjustment at the measurement date.

Is a stock exchange always an active market?

Not necessarily. A recognised exchange is often active for widely traded shares, but thinly traded securities on the same exchange may not meet the frequency and volume conditions. Activity is assessed for each specific asset or liability, not the venue as a whole.

Which accounting standards refer to an active market?

The term is used in the fair value requirements of FRS 102 and UK-adopted international accounting standards, including IFRS 13. Both use the concept to identify when a directly observable quoted price is available for measuring fair value.
