Australia Stock Market
P/E Ratio
20.56
15 August 2025

The estimated Price-to-Earnings (P/E) Ratio for Australia Stock Market is 20.56, calculated on 15 August 2025.

Considering the last 5 years, an average P/E interval is [14.80 , 19.11]. For this reason, the current P/E can be considered Overvalued

P/E Ratio is calculated on the EWA Etf, whose benchmark is the Australia Stock Market.

Historical P/E Ratio

When evaluating the P/E Ratio, it's important to not only look at its absolute value but also compare it to the average of previous periods. This allows for a more comprehensive understanding of the index/market valuation.

The following chart shows how the Australia Stock Market P/E Ratio has changed over time. Furthermore, for some trailing timeframes, you can view the average P/E and standard deviation.

Methodology

The Average P/E (μ) and the Standard Deviation (σ) are calculated excluding 20% outliers (i.e. over a range of values excluding 10% of observations from the top and 10% from the bottom of the dataset). Additionally, P/E values greater than 70 or lower than 1 are logarithmically normalized to reduce distortions.

A P/E between (μ - σ) and (μ + σ) is considered "Fair", over a specific timeframe.
A P/E greater than (μ + σ) is defined "Overvalued", greater than (μ + 2σ) is defined "Expensive".
A P/E less than (μ - σ) is defined "Undervalued", less than (μ - 2σ) is defined "Cheap".

Forward Return Evaluation

It is possible to estimate potential future returns using statistical models based on historical data and market patterns.

These forecasts are purely a statistical exercise and should never be relied upon as the basis for defining one’s investment strategy. They serve only as an analytical tool to explore possible scenarios, not as a guarantee of future performance.

Trailing vs Forward Return Model

This chart illustrates the relationship between trailing (past) returns and forward (subsequent) returns across various time ranges. Each point represents a specific period in the past, showing how past performance has (or hasn’t) correlated with future outcomes. By analyzing different time frames, the chart highlights the degree of persistence —or mean reversion— in investment returns over time.

The 200-day moving average is a long-term indicator that takes into account the average price of a stock over the past 200 trading days. It is considered a significant level of support or resistance, meaning that when the stock price is above the 200-day moving average (i.e. margin vs moving average is positive), it is generally viewed as bullish, while when it is below, it is viewed as bearish.
The 50-day moving average, on the other hand, is a shorter-term indicator that measures the average price of a stock over the past 50 trading days. It is also viewed as a significant level of support or resistance and can be used to identify shorter-term trends.
