How to Interpret $STRL Trades

Not every insider transaction in STERLING INFRASTRUCTURE, INC. is a signal for immediate action. Professional investors look for "cluster buying"—when multiple executives simultaneously purchase $STRL shares on the open market. It is crucial to distinguish between scheduled sales (under Rule 10b5-1) and voluntary increases in ownership, which demonstrate management’s true conviction that the stock is undervalued.

Data Source & Accuracy for STRL

Insider activity data for STERLING INFRASTRUCTURE, INC. is streamed in real-time directly from the SEC EDGAR system. We analyze raw Form 4 filings, filtering out technical adjustments and complex derivative transactions. This provides a transparent view of how ownership structure is evolving in $STRL, allowing you to follow the capital of those with the most intimate knowledge of the company.

UNDERSTANDING THE DATA

FILING DATE: The date and time when the transaction was reported to the SEC. This is when the public first receives the information.

TRADE DATE: The actual day the insider executed the purchase or sale in the market.

INDUSTRY: The specific market sector the company operates in. Useful for identifying broader institutional capital flows across sectors.

OWNED AFTER: The total number of shares held by the insider following the transaction. This highlights the insider's remaining conviction in the company.
