Caught the French market getting hammered on geopolitical concerns. The CAC 40 was down hard on Monday, sliding 1.63% to close around 8,440 points after dipping nearly 2.2% earlier in the session. Pretty brutal across the board.

The main culprit? Middle East tensions ramping up after coordinated US-Israel strikes on Iran and Tehran's retaliatory hits on bases in the region. When geopolitics flare up like that, you see immediate selling pressure everywhere. But here's what really caught attention - Brent crude spiked over 10% on supply disruption fears, hitting levels not seen since early 2025. That's the kind of move that gets inflation concerns back in the headlines real quick.

Sectorwise, it was a tale of two markets. Banking, luxury, and auto stocks got absolutely crushed - Accor down 8.6%, LVMH and Kering off 3-5%, Renault and Stellantis in similar territory. Even the big names like BNP Paribas and Societe Generale couldn't escape the selling. Meanwhile, defense plays like Thales were actually up 3.6% - makes sense when tensions spike. TotalEnergies managed a 4.3% gain riding the oil move higher.

On the economic side, France's manufacturing PMI came in at 50.1 for February, down from 51.2 in January. Basically signaling the sector is just treading water - no real momentum either direction. Combined with the geopolitical uncertainty, you can see why the CAC 40 was getting pressured pretty hard that day.

This is the kind of volatility that reminds you why watching macro conditions and geopolitical risk matters just as much as individual stock picks. Markets don't like uncertainty, and that's exactly what was priced in.
