How Did the CAC 40 Perform Today?

The CAC 40 gained 0.71% to close at 7,753 points on Tuesday, August 13, 2025, erasing Monday’s dip with interest. Trading volumes stayed thin—typical for August, when half-year earnings season winds down and traders hit the beach. It’s like the market’s running on autopilot, but hey, at least it’s moving in the right direction.

What Drove the Market’s Optimism?

Two key factors:and. The U.S. and China extended their tariff ceasefire for 90 days, avoiding a fresh round of 100%+ duties. Over in Washington, July’s CPI data landed as expected (up 0.2% monthly, 2.7% yearly), easing fears of runaway inflation. Core CPI—excluding food and energy—rose 0.3% from June and 3.1% year-over-year. Not exactly fireworks, but in this economy, boring is beautiful.

Which Stocks Were the Biggest Movers?

stole the show, rocketing 9% after reporting a 37.8% jump in H1 revenue to €97.6M, fueled by its Ixiaro/Jespect vaccine. Despite a net loss of €20.8M (vs. a €34M profit in H1 2024), the company slashed operating cash burn by 84% and reaffirmed its 2025 targets. Other standouts:

What About Macro Trends?

The euro edged up to 1.17/$, Brent crude held above $66, and bitcoin lingered below $120K—no record breaks, but no meltdowns either. All eyes now turn to Friday’s Trump-Putin summit in Alaska, though hopes for a Ukraine breakthrough dimmed after Trump’s recent cautious remarks. As one BTCC analyst quipped, "It’s less ‘peace in our time’ and more ‘let’s not start WWIII before lunch.’"

Why Does Summer Trading Matter?

Thin volumes amplify moves—like shouting in an empty stadium. With earnings season over, markets latch onto macro cues (hence the CPI/Tariff reactions). Historical data from TradingView shows August volatility typically dips 15-20%, but 2025’s geopolitical spice rack could rewrite the script.

What’s Next for Investors?

Watch three catalysts: (1)in November, (2)after soft employment data, and (3)in October. For crypto traders on BTCC, Bitcoin’s $120K resistance remains the line in the sand. This article does not constitute investment advice.
