Wall Street heads into Wednesday with buyout talk, earnings paradoxes and defence strength setting the tone — plus a fresh set of disclosed insider trades for investors to parse.

Qiagen climbed about 7 per cent on reports of advanced buyout talks with private equity firm EQT, a sign that private equity is still hunting life-sciences assets. BlackBerry rose about 8 per cent on a strong backlog for its QNX embedded software, as the company's pivot away from handsets continues to gain traction. In the earnings paradox of the season, General Motors and GE Aerospace both beat expectations and raised guidance — and both stocks fell anyway, a reminder that “sell the news” is alive and well. Defence names stayed quietly strong, with Northrop Grumman and RTX posting solid results, while Alpha Teknova plunged about 22 per cent after hours on a dilutive public offering.

On the insider tape, filings show Parex Resources insider Michael Kruchten sold 21,382 shares. Parex, the Calgary-headquartered oil and gas producer focused on Colombia, carries a consensus “Hold” rating and an average price target of C$26.62, according to MarketBeat data. Insider transactions are disclosed for many reasons — including pre-arranged trading plans — and are reported here as market news only.

The backdrop remains dominated by the quarter's biggest story: SpaceX's first earnings as a public company, with third-quarter revenue surging, ignited a broad rally in AI and chip stocks this week. Nothing in this report is a recommendation or advice to trade.
