About PRM insider trading
This page tracks insider transactions for Perimeter Solutions, Inc. (PRM) reported to the U.S. Securities and Exchange Commission on Form 4. Corporate insiders — directors, executive officers and beneficial owners of more than 10% of the stock — must disclose their trades within two business days. Open-market purchases (code P) and sales (code S) made at the insider's discretion are the most-watched opportunistic signals, while awards (A), option exercises (M) and tax-withholding (F) reflect compensation rather than conviction. Trades marked 10b5-1 were made under a pre-arranged plan and are considered routine. A cluster buy — several insiders buying within a short window — is historically a stronger bullish indicator than any single trade.
