Engineering Services - Insider Trading Data

Insiders are officers, directors, or significant investors. This page shows insider sentiment and transactions for the Engineering industry. Research shows that insider trades are predictive of future stock returns. By examining insider trades for an industry, we can understand what well-informed people think of the overall future industry prospects.

Engineering Services - Insider Buy/Sell Ratio

Insider selling and buying is a useful indicator for analyzing the market because it serves as a proxy for their optimism or pessimism in their own companies. By looking at ratio of total selling and buying across the entire market, we might be able to draw some conclusions about the future market.

We offer two charts here. The first one shows the total dollar volume of buying and selling by insiders. The second chart shows the ratio of the number of insiders selling, vs. the number of insiders buying. In both charts, we filter out trades made by indirect holders (such as trusts), and 10% owners (who, although considered an 'insider' by the SEC, do not actually manage the companies in which they are considered insiders).
