It is not uncommon to see companies perform well in the years after insiders buy shares. Unfortunately, there are also plenty of examples of share prices declining precipitously after insiders have sold shares. So we'll take a look at whether insiders have been buying or selling shares in Protagonist Therapeutics, Inc. (NASDAQ:PTGX).

Do Insider Transactions Matter?

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, most countries require that the company discloses such transactions to the market.

We don't think shareholders should simply follow insider transactions. 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'.

Protagonist Therapeutics Insider Transactions Over The Last Year

Over the last year, we can see that the biggest insider purchase was by Independent Chairman Harold Selick for US$80k worth of shares, at about US$6.70 per share. We do like to see buying, but this purchase was made at well below the current price of US$19.69. Because the shares were purchased at a lower price, this particular buy doesn't tell us much about how insiders feel about the current share price.

Does Protagonist Therapeutics Boast High Insider Ownership?

Another way to test the alignment between the leaders of a company and other shareholders is to look at how many shares they own. Usually, the higher the insider ownership, the more likely it is that insiders will be incentivised to build the company for the long term. Insiders own 1.2% of Protagonist Therapeutics shares, worth about US$10m. This level of insider ownership is good but just short of being particularly stand-out. It certainly does suggest a reasonable degree of alignment.

What Might The Insider Transactions At Protagonist Therapeutics Tell Us?

The fact that there have been no Protagonist Therapeutics insider transactions recently certainly doesn't bother us. But insiders have shown more of an appetite for the stock, over the last year. Overall we don't see anything to make us think Protagonist Therapeutics insiders are doubting the company, and they do own shares. So these insider transactions can help us build a thesis about the stock, but it's also worthwhile knowing the risks facing this company. For example, Protagonist Therapeutics has 3 warning signs (and 1 which shouldn't be ignored) we think you should know about.
