Understanding Wash Trading
The discrepancy between substantial trading activity and unchanged share registry records for specific participants can be attributed to:
- Nominee Accounts and Custodial Holdings:Trading within these structures leads to changes in beneficial ownership without affecting the registered holdings.
- Derivatives and Alternative Instruments:High volumes in these markets impact perceptions and prices but do not require share transfers reflected on the registry.
- Wash Trading (Market Manipulation):Illegal practices create artificial activity without genuine ownership changes, leaving registry records untouched.
Understanding these factors is crucial for interpreting market activity accurately.Investors and market observers should consider that not all trading activity directly translates to changes in share ownership recorded on the registry.
The chart you’ve provided shows the
2-hour timeframefor
OncoSil Medical Ltd (ASX: OSL), which gives a medium-term perspective on the stock’s price action and volume dynamics. Given your question about
share washing, let's analyse the current price and volume behaviour to see if any signs point toward possible
wash trading.
Understanding Share Washing (Wash Trading)
- Share washing, also known aswash trading, is a form of market manipulation where the same party simultaneously buys and sells the same security to create artificial trading volume and misleading market activity.
- The primary goal of wash trading is toinflate trading volumes,create false liquidity, andmislead other investorsabout the actual demand or supply of the stock. It’s illegal in most markets and is closely monitored by regulators.
Analysis of the Chart
Here are the observations from the chart and how they might relate to wash trading:
1. Volume Spikes and Price Movement
- Volume Surges:The chart shows a few isolated volume spikes, especially during periods of sharp declines. In legitimate trading, these spikes typically align with significant news or major events, but if they occur without corresponding news, it could indicateartificial trading activity.
- Price Impact:Despite the volume spikes, the price continues to decline or remains relatively flat. This pattern can be suspicious because normal buying interest should, in theory, provide some level of price support.
- If the volume is significantly high but fails to move the price upwards or stabilize it, it could suggest that the trades are not genuine transactions aimed at changing ownership but rather wash trades designed to inflate volume.
2. Repeated Round-Trip Trades
- Round-Trip Transactions:In potential wash trading, you might observe repetitive buying and selling patterns, often within short intervals. If similar buy and sell volumes are recorded over a short period (e.g., within a few 2-hour candles), it could be indicative of wash trading.
- The chart appears to show erratic but consistent volume spikes without meaningful directional price movement. This could be a sign of round-trip trades where the same volume enters and exits the market quickly to create an illusion of activity.
3. Money Flow Index (MFI) Insights
- TheMFI (14)is currently at15.50, indicating anoversold condition, which generally suggests that sellers are dominant. However, the MFI's decline alone cannot confirm wash trading.
- In a wash trading scenario, the MFI may remain oversold if the artificial trading is primarily aimed at maintaining low prices, potentially to accumulate shares at lower levels or manipulate perceptions of demand.
- The oversold MFI, combined with high volumes and persistent downward pressure, raises concerns about whether genuine buying interest is absent or suppressed.
4. Consistent Downtrend Despite Volume
- The sustained decline in share price, despite occasional volume spikes, may indicateartificial selling pressure. Wash trading can be employed tosuppress the price deliberatelyby maintaining apparent selling pressure.
- If entities engage in wash trading to keep the price low, it could align with strategic motives, such as deterring new buyers or creating a perception of weak demand, potentially for takeover positioning or accumulation at lower levels.
5. Lack of Positive Follow-Through
- Generally, when legitimate buying occurs on high volume, some follow-through is expected in the subsequent candles (e.g., price support or upward movement).
- In the chart, the absence of any meaningful price recovery, even after high-volume candles, suggests that the trades may not reflect genuine investor demand but could be part of manipulative activity aimed atvolume creationrather than price discovery.
Could It Be Wash Trading?
Based on the observations above,it is possiblethat the unusual volume patterns, lack of positive price reaction, and persistent downtrend in the face of high volume could be indicative of wash trading. However, this is speculative and requires more detailed trade data to confirm, as wash trading is generally detected through specific patterns such as:
- Rapid buy-sell transactions between the same counterparties.
- Simultaneous orders that match at similar prices.
- Minimal changes in beneficial ownership despite high volume.
Regulatory Considerations
- Wash trading is illegal in most markets, including the ASX, and is considered a severe violation of securities law. Regulators, such as the Australian Securities and Investments Commission (ASIC), monitor trading activity for signs of manipulation.
- If wash trading is suspected, regulators can investigate by examining trade data, broker records, and account activities to determine if any manipulation has occurred.
Conclusion
While the chart shows some characteristics that could align with wash trading, more concrete data, such as order book analysis, trade timestamps, and counterparty details, would be needed to definitively identify wash trading. The current analysis indicates unusual trading behaviour, but without direct evidence, it remains speculative.
If you are concerned about potential market manipulation, it may be worth reporting the activity to regulators or consulting with market surveillance professionals who can access detailed trade-level data for a more thorough investigation.

Understanding the Discrepancy Between High Trading Volumes and Unchanged Share Registry Records
When a company experiences significant trading activity following positive news and a capital raise, but the share registry does not reflect changes in holdings for certain participants, several factors could explain this phenomenon. Focusing on the use of nominee accounts, trading through derivatives, and potential market manipulation practices like wash trading, we can explore why the trading volumes are not mirrored in the share registry.
1. Use of Nominee Accounts and Custodial Holdings
One plausible explanation is that shares are being traded through nominee accounts or custodial holdings, which can obscure the actual changes in beneficial ownership on the share registry.
Impact:
- Unchanged Registry Records:Despite significant trading activity, the share registry shows no change for specific participants because the trades occur within the nominee structure.
- Hidden Beneficial Ownership Changes:The actual shifts in ownership happen behind the scenes, not immediately visible to the public or reflected in the registry.
2. Trading Through Derivatives and Alternative Financial Instruments
Another reason could be that investors are engaging in trading activities involving derivatives or alternative instruments that do not necessitate changes in the share registry.
Impact:
- High Market Activity Without Registry Changes:Significant trading in derivatives can influence the stock's price and trading volumes without altering the actual ownership records.
- Market Perception vs. Registry Data:The market may perceive high activity due to derivative trading, but the share registry remains unaffected because no shares have changed hands.
3. Wash Trading and Market Manipulation
A less likely but possible explanation involves wash trading, where artificial trading activity is created to mislead market participants.
Definition of Wash Trading:
- Simultaneous Buying and Selling:An entity buys and sells the same financial instruments simultaneously, creating the illusion of market activity.
- No Change in Beneficial Ownership:Since the same party controls both sides of the trade, there is no real transfer of ownership, leaving the share registry unchanged.
Motivations Behind Wash Trading:
- Price Manipulation:To artificially inflate or suppress the stock price for strategic purposes, such as influencing a capital raise or a takeover bid.
- Volume Inflation:To create a perception of liquidity or heightened interest in the stock, potentially attracting other investors.
Legal and Ethical Considerations:
- Illegality:Wash trading is illegal in most jurisdictions as it distorts market realities and undermines market integrity.
- Regulatory Scrutiny:Regulators actively monitor for such activities, and entities caught engaging in wash trading face severe penalties.
Impact:
- Misleading Trading Volumes:High trading volumes are recorded, but they do not represent genuine market interest or changes in ownership.
- Unchanged Share Registry:Because ownership doesn't change, the share registry for particular participants remains the same despite apparent market activity.
Conclusion
The discrepancy between substantial trading activity and unchanged share registry records for specific participants can be attributed to:
- Nominee Accounts and Custodial Holdings:Trading within these structures leads to changes in beneficial ownership without affecting the registered holdings.
- Derivatives and Alternative Instruments:High volumes in these markets impact perceptions and prices but do not require share transfers reflected on the registry.
- Wash Trading (Market Manipulation):Illegal practices create artificial activity without genuine ownership changes, leaving registry records untouched.
Understanding these factors is crucial for interpreting market activity accurately.Investors and market observers should consider that not all trading activity directly translates to changes in share ownership recorded on the registry.
Recommendations
Enhanced Transparency:
- Regulatory Oversight:Regulators should ensure that nominee and custodial holdings are transparent enough to prevent misuse while respecting privacy laws.
- Reporting Requirements:Strengthening reporting standards for derivatives and custodial holdings can improve market clarity.
Investor Vigilance:
- Due Diligence:Investors should look beyond trading volumes and consider underlying factors such as ownership structures and the nature of trading activities.
- Awareness of Market Manipulation:Being informed about practices like wash trading can help investors make better decisions and report suspicious activities.
Company Communication:
- Regular Updates:Companies should provide timely updates on significant changes in shareholdings, especially after events like capital raises.
- Engagement with Shareholders:Open communication can help alleviate concerns arising from discrepancies between trading activity and share registry records.
By focusing on these explanations, we gain a comprehensive understanding of why significant trading volumes may not be reflected in changes on the share registry for particular participants. Recognizing the roles of nominee accounts, derivatives trading, and the potential for market manipulation provides valuable insights into the complexities of modern financial markets.
