Investors often look at insider buying and selling for clues during turbulent markets. These trades, made by company executives and directors, are usually seen as signs of confidence or concern. But new research released this week shows these signals become much less reliable when volatility rises. In fast-changing markets, insiders seem no better than anyone else at spotting turning points. Their trades can even mislead investors who hope for clear answers.
The findings come at a difficult time for global markets. The FTSE 100 has swung sharply this autumn as expectations for Bank of England rate cuts shift. Concerns about slowing global growth and stubborn inflation add further pressure. In this environment, investors turn to insider activity for guidance, believing it reveals what leaders really think.

New Research Challenges Old Assumptions
The study looked at thousands of insider trades made during big market swings. It found that investors often give these trades too much importance when markets are unstable. Insider buying is usually seen as a strong sign of confidence, but during volatile periods it was much less useful. Executives faced the same uncertainty as everyone else. Many bought shares without knowing how long the downturn would last or how bad it might get.
Insider selling also increased, but mostly for normal personal reasons. Some executives needed cash, some had tax bills to pay, and others were simply rebalancing their portfolios. Many sales came from automatic trading plans that were set up long before market conditions changed. These trades did not reveal much about the company’s future.
Analysts say this pattern is similar to what happened during the pandemic. Insider buying jumped when share prices fell, but many of those trades were based on hope rather than clear insight. Some worked out well, but many did not. The study also noted that insiders must follow strict trading rules, which makes their decisions harder to interpret during volatile times.
Another issue is timing. Insider trades are often reported days after they happen. By the time the public sees the filing, the share price and market conditions may have already changed. This delay can lead investors to react to signals that no longer match reality.
All these factors show why insider activity becomes a weaker indicator during market shocks and why relying on it alone can lead to poor decisions.
Why Insider Signals Break Down During Shocks
Several reasons weaken insider signals during volatile periods. Executives often react emotionally. They may buy shares to show confidence or because prices look cheap. This does not mean they know how the company will perform later. They also face strict rules on when they can trade. These windows can cause trades to cluster at times that do not reflect wider market conditions.
Volatility also creates a lot of noise. Sharp price drops can hide whether a company is truly weakening or simply caught in panic selling. Even insiders struggle to tell the difference. Analysts warn that during these periods, it is easy to mistake emotion for insight.
Where Insider Data Still Helps
Insider activity can still be helpful when it shows clear patterns. If several insiders buy shares at the same time, it can signal they believe the stock is too cheap. This is especially useful in smaller companies, where executives often know more about demand, new contracts, and financial strength.
Insider buying that continues after a long decline can also suggest growing confidence in a recovery. These signals matter most when the company’s results improve at the same time, such as rising sales or stronger cash flow.
Analysts say insider data tends to work best in calmer markets, when decisions reflect long-term planning rather than short-term stress.
Signals That Mislead More Than They Inform
Insider selling often creates confusion. Executives sell shares for many personal reasons that have nothing to do with the company. They may diversify their investments, pay bills, or meet tax requirements. Automatic selling plans also weaken the message, as these trades happen at set times and do not reflect real-time decisions.
In volatile markets, investors may misread routine sales as warnings. Some even chase insider patterns across several companies. Economists caution that during fearful periods, people look for simple explanations, but these signals are least reliable when panic sets in.
How Investors Can Use Insider Information More Wisely
Insider trades should support an investment decision, not guide it on their own. These trades can show how confident executives feel, but investors need to compare them with real evidence. This includes company results, market sentiment, earnings trends, and what is happening across the sector.
For ISA or pension investors, insider buying is more meaningful when the business is already improving. Rising sales, better cash flow, or lower debt make insider confidence easier to trust. If the company is moving in the right direction, insider buying may point to further progress, not just a short-term reaction to market swings.
Professional investors often compare insider activity with analyst upgrades and trading trends. They pay attention when executives buy shares at the same time analysts raise forecasts or when liquidity improves. This can show that insiders expect a real change, not a brief bounce.
Private investors can use the same approach. One insider trade rarely says much. What matters is whether insider behaviour matches real developments, such as new contracts, a stronger order book, or steadier profit margins. When these signs line up, insider activity becomes more reliable.
A Tool That Needs Care In Turbulent Markets
Insider data will remain a common part of market research. It offers a look at how leaders act when their own money is at risk. But high volatility reduces the value of these signals. Investors who rely too much on insider buying or selling may end up mistaking emotion for insight.
As markets react to shifting interest rates and uneven global growth, stronger guidance will come from a mix of fundamentals and behaviour. Insider trades will still matter, but they work best when they support a wider view, not replace it. Future market shocks will test how well investors understand the limits of insider activity in uncertain times.
