How Much Are Sienna Cancer Diagnostics Limited (ASX:SDX) Insiders Spending On Buying Shares?

We often see insiders buying up shares in companies that perform well over the long term. The flip side of that is that there are more than a few examples of insiders dumping stock prior to a period of weak performance. So shareholders might well want to know whether insiders have been buying or selling shares in Sienna Cancer Diagnostics Limited (ASX:SDX).

Do Insider Transactions Matter?

It’s quite normal to see company insiders, such as board members, trading in company stock, from time to time. 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 equally, we would consider it foolish to ignore insider transactions altogether. 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’.

While this is a strong but not outstanding level of insider ownership, it’s enough to indicate some alignment between management and smaller shareholders.
