Have Insiders Been Buying Sienna Cancer Diagnostics Limited (ASX:SDX) Shares?

Simply Wall St

We often see insiders buying up shares in companies that perform well over the long term. On the other hand, we'd be remiss not to mention that insider sales have been known to precede tough periods for a business. So shareholders might well want to know whether insiders have been buying or selling shares in Sienna Cancer Diagnostics Limited (ASX:SDX).

What Is Insider Buying?

Most investors know that it is quite permissible for company leaders, such as directors of the board, to buy and sell stock in the company. However, rules govern insider transactions, and certain disclosures are required.

We would never suggest that investors should base their decisions solely on what the directors of a company have been doing. But it is perfectly logical to keep tabs on what insiders are doing. For example, a Columbia University study found that 'insiders are more likely to engage in open market purchases of their own company’s stock when the firm is about to reveal new agreements with customers and suppliers'.
