RF Industries is trading at $8.48, up +6.67%, in pre-market, with no clear catalyst identified. - This compares with the October 13 close of $7.95. - The company’s latest earnings and Russell 3000 inclusion news surfaced in September, not as new October 14 developments. - Major indices are only modestly higher, so the gain cannot be confidently attributed to broad-market sentiment; the reason remains unclear.
