Insiders Who Sold US$839k Of Clean Energy Fuels Made The Right Call

Simply Wall St

While it’s been a great week for Clean Energy Fuels Corp. (NASDAQ:CLNE) shareholders after stock gained 10%, they should consider it with a grain of salt. Although prices were relatively low, insiders chose to sell US$839k worth of stock in the past 12 months. This could be a sign of impending weakness.

Although we don't think shareholders should simply follow insider transactions, we do think it is perfectly logical to keep tabs on what insiders are doing.

Clean Energy Fuels Insider Transactions Over The Last Year

Over the last year, we can see that the biggest insider sale was by the Co-Founder, Andrew Littlefair, for US$563k worth of shares, at about US$2.25 per share. So it's clear an insider wanted to take some cash off the table, even below the current price of US$2.65. We generally consider it a negative if insiders have been selling, especially if they did so below the current price, because it implies that they considered a lower price to be reasonable. While insider selling is not a positive sign, we can't be sure if it does mean insiders think the shares are fully valued, so it's only a weak sign. We note that the biggest single sale was only 18% of Andrew Littlefair's holding.

In total, Clean Energy Fuels insiders sold more than they bought over the last year. You can see a visual depiction of insider transactions (by companies and individuals) over the last 12 months, below. If you want to know exactly who sold, for how much, and when, simply click on the graph below!

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. We usually like to see fairly high levels of insider ownership. Clean Energy Fuels insiders own about US$11m worth of shares. That equates to 1.8% of the company. This level of insider ownership is good but just short of being particularly stand-out. It certainly does suggest a reasonable degree of alignment.
