Executives of ASX shares often signal confidence—or concern—about the future of their organisations through their buying and selling actions.

Over the past week or so, there's been some notable trading activity among directors of Incitec Pivot Ltd (ASX: IPL), Bendigo and Adelaide Bank Ltd (ASX: BEN), Aussie Broadband Ltd (ASX: ABB), and REA Group Ltd (ASX: REA).

Here's a rundown of recent director transactions.

Which ASX 300 shares were bought?

One ASX 300 share that's seen some heavy-duty buying activity from insiders this month is Incitec Pivot.

Director John Ho made a significant purchase of the company's common stock on 12 November, acquiring 1.6 million shares on-market at an average price of $3.01 per share.

This brings his total holding to 174.66 million shares. Some might argue such a large purchase from someone with skin in the game suggests strong confidence in Incitec's growth prospects.

Which directors are selling down?

Meanwhile, Owen Wilson, CEO of REA Group, sold down some of his shares in the ASX 300 digital advertising company.

His disposal of 15,000 ordinary shares last week was valued at over $3.5 million, according to filings.

Bendigo Bank director Richard Allan Fennell sold 25,000 ordinary shares last week, reducing his direct stake in the company to 43,541 shares.

The bank's shares have caught a bid alongside the broader sector in recent months, and have nudged to 52-week highs in the days following the sales.

At the bank's current share price, Allan Fennell's position is worth over $584,000.

Finally, Aussie Broadband director Michael Omeros offloaded 200,000 shares at $3.75 per share, representing a value of $750,000.

While his sale decreases his direct holding to 415,181 shares, he retains substantial indirect holdings as well through restricted stock units and performance rights with the company's long-term incentive plan.
