投机 (tóu jī) — to speculate (on financial markets); opportunistic; (of conversation or interaction) congenial, agreeable

Two unrelated senses: financial 'to speculate / opportunistic' (contrast with 推测 'to infer from evidence', and 炒股 'speculate in stocks' which is stock-specific) — and in conversation, 'congenial, hitting it off' (no sibling matches this sense).
