Here are five key things investors need to know to start the trading day:

Berkshire Hathawayadded $17 billion to itsAlphabetstake in the second quarter, according to a regulatory filing released Friday, making the Google parent thethird largest holdingin the conglomerate's portfolio. That wasn't the only news to come out of Friday's filings.

Barely more than a week after a loss in New Mexico,Metaisheading back to court. Opening arguments begin tomorrow for the case against the Facebook parent being co-led by California Attorney General Rob Bonta.

As CNBC'sJonathan Vanianreports, the group of 29 state attorneys general are pushing a unified case against Meta, alleging that the company violated federal and state laws. "You could wake up with a headline judgment that is, as I've said, astronomical," New Mexico AG Raul Torrez said, fresh off his win against Meta earlier this month.

The wave of legal challenges against Meta represent a "Big Tobacco" moment for social media, according to industry experts. A loss in the company's home state of California — one of the most important and influential jurisdictions in the U.S. — could be particularly staggering.

Champagne makers are experiencing an alcohol-induced headache. But it's not in the way you might expect.

In Europe, hotter summers have made grape harvesting seasons shorter and earlier. The grapes are more sugary as a result, which isposing a dilemmafor producers of the sparkling wine: If they harvest early to reduce the sugar content, winemakers risk not achieving the desired flavor and texture.

On top of extreme heat and freak weather events, European winemakers are also grappling with declining demand, rising costs and the impact of U.S. tariffs.
