Viewing insider transactions for Plug Power Inc.'s (NASDAQ:PLUG ) over the last year, we see that insiders were net sellers. This means that a larger number of shares were sold by insiders in relation to shares purchased.

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.

Plug Power Insider Transactions Over The Last Year

The Executive VP & GM of Material Handling, Jose Crespo, made the biggest insider sale in the last 12 months. That single transaction was for US$230k worth of shares at a price of US$7.20 each. We generally don't like to see insider selling, but the lower the sale price, the more it concerns us. The silver lining is that this sell-down took place above the latest price (US$2.57). So it may not shed much light on insider confidence at current levels. Jose Crespo was the only individual insider to sell over the last year.
