Rate of Change (ROC): A Powerful Tool for Australian Investors in 2025

In the fast-paced world of investing, knowing when to buy, hold, or sell can make or break your portfolio. While there’s no magic crystal ball, smart investors are turning to technical indicators like Rate of Change (ROC) to read the market’s pulse. As 2025 brings new volatility and regulatory shifts in Australia, understanding ROC could be your edge for sharper, more confident decisions.

What Is Rate of Change (ROC) and Why Should You Care?

Rate of Change is a momentum oscillator that measures the percentage change in price between the current value and a previous value over a set period. In plain English, it tells you how fast (and in what direction) a stock, ETF, or index is moving. The ROC can signal when momentum is building, waning, or about to reverse.

• Above zero: Upward momentum – buyers are in control.

• Below zero: Downward momentum – sellers dominate.

• Extreme highs/lows: Potential overbought or oversold signals.

With ASX volatility in 2025, thanks to inflation jitters and ongoing RBA policy shifts, ROC is gaining traction among Aussie retail traders and SMSF managers alike.

How to Use ROC in Your Trading or Investing Strategy

Let’s get practical. Imagine you’re watching shares in an ASX-listed tech company. After a strong run, the ROC spikes above historical highs. Is it time to take profits?

• Entry signals: Some investors use ROC crossovers above zero as a sign to buy, betting on building momentum.

• Exit signals: Others watch for ROC dropping below zero or peaking at extreme levels, suggesting a reversal could be near.

• Divergence: If the price hits new highs but the ROC doesn’t, it could warn of fading momentum – a red flag for cautious investors.

In 2025, this approach is especially valuable as sectors like renewables and lithium mining experience rapid swings tied to global policy and commodity prices. For example, in February 2025, several Aussie battery stocks surged after the Federal Government expanded EV incentives – ROC helped traders spot the initial momentum and manage their exits as the hype faded.

Policy and Market Trends: Why ROC Matters More Than Ever in 2025

Australian investors face a unique landscape this year:

• Superannuation reforms: Changes to contribution caps and tax rules have many SMSFs rebalancing portfolios, increasing market churn.

• Tech-driven trading: More brokers offer ROC and momentum tools within their platforms, making sophisticated analysis accessible to everyday Aussies.

• Heightened market swings: Ongoing RBA rate changes, cost-of-living pressures, and global uncertainty are fueling larger, faster price moves – making momentum tracking like ROC more relevant.

For instance, the March 2025 RBA rate pause saw ROC on major bank stocks flip from negative to positive within days, offering nimble traders a clear read on shifting sentiment.

Limitations and Best Practices for ROC in 2025

Like any tool, ROC isn’t foolproof. It can whipsaw in sideways markets and generate false signals during choppy trading sessions. Combine ROC with other indicators (like moving averages or RSI) and always consider broader fundamentals and news flow.

• Test your ROC strategies with historical ASX data before going live.

• Stay alert to policy updates that can drive sudden momentum shifts.

• Don’t ignore fees and taxes – even the best signals can be undermined by high trading costs.
