Painting the Tape: Market Manipulation Risks for Australian Investors in 2025

When it comes to stock markets, not all trading is as transparent as it seems. One deceptive tactic that’s back in the spotlight for 2025 is ‘painting the tape’. While it sounds like something from an art studio, it’s actually a form of market manipulation that regulators in Australia are watching closely. Here’s what every investor should know about this practice, how to recognise it, and the latest policy moves to crack down on it.

What Is ‘Painting the Tape’?

‘Painting the tape’ refers to a group of traders or entities buying and selling a security among themselves to create artificial trading activity. The goal? To make it look like there’s strong interest in a stock, hoping to lure unwitting investors into jumping on what appears to be momentum. Once the price is inflated, manipulators offload their holdings at a profit, often leaving everyday investors exposed to sudden price drops.

• Example: A penny stock trades at low volume. Suddenly, a series of rapid-fire trades pushes the price up 20% in an hour. Social media buzzes with excitement, but the activity was orchestrated by a handful of accounts.
• ‘Tape’ refers to the old ticker tape machines that reported trades; ‘painting’ is manipulating what investors see.

Why Is It a Hot Topic in 2025?

With digital trading platforms, algorithmic bots, and the rise of retail investing, the Australian Securities and Investments Commission (ASIC) has made market manipulation a priority for 2025. The following trends are bringing ‘painting the tape’ back into focus:

• Increased algorithmic trading: Bots can execute hundreds of trades per second, making it easier to simulate fake demand.
• Social media pump-and-dump groups: Telegram and Discord channels are being used to coordinate suspicious trading patterns.
• ASIC’s crackdown: In early 2025, ASIC launched a new surveillance initiative using AI-driven monitoring to detect abnormal trading spikes. Several high-profile cases have led to fines and trading bans.

According to ASIC’s latest market integrity report, there’s been a 17% rise in suspicious trading alerts linked to small-cap stocks since 2023. This has led to renewed calls for tougher penalties and more investor education campaigns.

How to Spot ‘Painting the Tape’ as an Investor

While it can be tricky to distinguish legitimate momentum from manipulated activity, there are some classic red flags every investor should watch for:

• Unusual volume spikes: Sudden surges in trading volume, especially in thinly traded stocks, without any clear news or announcements.
• Price whipsaws: Rapid swings up and down over a short period, often reversing sharply after a spike.
• Coordinated social media hype: If multiple online accounts are aggressively promoting a stock with little substance, be wary.
• Repeated small trades: A pattern of many small trades at slightly different prices, designed to show a constant stream of activity.

ASIC has published updated investor guidelines in 2025, urging caution around stocks displaying these patterns. They also recommend using official sources—such as the ASX announcements and company filings—rather than relying on social media tips.

What Are the Legal and Financial Risks?

‘Painting the tape’ is illegal in Australia under the Corporations Act 2001, with penalties including substantial fines and potential jail time. ASIC’s enforcement actions in 2025 have already resulted in several bans for individuals and entities caught manipulating the market.

For investors, the risks are equally real. Buying into a stock that’s being manipulated can lead to sudden losses when the artificial price support evaporates. In a recent case, shares of a small-cap tech company soared 40% in a day before dropping 35% the next, after ASIC intervened and suspended trading pending investigation.

Protecting Yourself in 2025’s Market

• Always research the underlying business fundamentals and news before trading on momentum.
• Be cautious of tips from anonymous online sources or chat groups.
• If a price move seems too good to be true, it probably is—especially in illiquid stocks.
• Use limit orders to avoid getting caught in wild price swings.

Australian investors should also keep an eye on ASIC’s market integrity updates and make use of the regulator’s online reporting tools if they spot suspicious activity.
