Tyler Technologies is selling off in after-hours trading following a regular session that saw the stock under mild pressure. While the company recently secured contract expansions with the South Carolina DMV and received an upgrade to a Buy rating on October 1, these positive developments have been overshadowed by the significant downward momentum. Given that no new earnings or material filings were released after the close to justify this move, the stock appears to be reacting to technical selling pressure or broader market volatility rather than company-specific news.
