Read This Before Buying Power Integrations, Inc. (NASDAQ:POWI) Shares

Simply Wall St

We often see insiders buying up shares in companies that perform well over the long term. 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 Power Integrations, Inc. (NASDAQ:POWI).

What Is Insider Selling?

It is perfectly legal for company insiders, including board members, to buy and sell stock in a company. However, such insiders must disclose their trading activities, and not trade on inside information.

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 Harvard University study found that 'insider purchases earn abnormal returns of more than 6% per year.'

Power Integrations Insider Transactions Over The Last Year

Over the last year, we can see that the biggest insider sale was by the CFO & VP of Finance, Sandeep Nayyar, for US$1.8m worth of shares, at about US$90.50 per share. So it's clear an insider wanted to take some cash off the table, even slightly below the current price of US$91.62. When an insider sells below the current price, it suggests that they considered that lower price to be fair. That makes us wonder what they think of the (higher) recent valuation. However, while insider selling is sometimes discouraging, it's only a weak signal. This single sale was just 25.8% of Sandeep Nayyar's stake.

Over the last year we saw more insider selling of Power Integrations shares, than buying. The average sell price was around US$75.81. It's not too encouraging to see that insiders have sold at below the current price. But we wouldn't put too much weight on the insider selling.

Power Integrations Insiders Are Selling The Stock

Over the last three months, we've seen significant insider selling at Power Integrations. In total, insiders dumped US$4.1m worth of shares in that time, and we didn't record any purchases whatsoever. This may suggest that some insiders think that the shares are not cheap.

Insider Ownership

Many investors like to check how much of a company is owned by insiders. Usually, the higher the insider ownership, the more likely it is that insiders will be incentivised to build the company for the long term. Power Integrations insiders own 3.8% of the company, currently worth about US$103m based on the recent share price. I like to see this level of insider ownership, because it increases the chances that management are thinking about the best interests of shareholders.

So What Do The Power Integrations Insider Transactions Indicate?

Insiders sold stock recently, but they haven't been buying. Zooming out, the longer term picture doesn't give us much comfort. But since Power Integrations is profitable and growing, we're not too worried by this. The company boasts high insider ownership, but we're a little hesitant, given the history of share sales.
