According to @StockMKTNewz, U.S. 18-29-year-olds are the least likely to own a credit card and the least likely to carry a month-to-month credit card balance, highlighting a weaker participation of the youngest cohort in revolving credit (source: @StockMKTNewz). For traders, this cohort profile points to lower revolving-credit participation and interest income contribution from younger consumers relative to older groups, an input for modeling revenue mix at credit card issuers and networks (source: @StockMKTNewz). Equity watch: Visa (V), Mastercard (MA), American Express (AXP), Capital One (COF), and Discover (DFS) exposure to U.S. youth revolving balances should reflect the lower card ownership and balance-carrying rates cited for ages 18-29 (source: @StockMKTNewz).

According to @StockMKTNewz, Berkshire Hathaway’s top holdings in Q2 2015 were Wells Fargo (WFC) 24.1%, Coca-Cola (KO) 14.3%, and IBM 11.8%, highlighting a bank and consumer-staples tilt at that time, source: @StockMKTNewz. By Q2 2025, the top three shifted to Apple (AAPL) 22.3%, American Express (AXP) 18.8%, and Bank of America (BAC) 11.1%, concentrating exposure in mega-cap tech and financials, source: @StockMKTNewz. This reweighting makes Berkshire’s public-equity performance more sensitive to AAPL, AXP, and BAC price action than a decade ago, a concentration dynamic derived from the stated position sizes, source: @StockMKTNewz. For crypto traders, IMF research documents that BTC’s correlation with U.S. equities increased notably post-2020, making AAPL-led risk sentiment a relevant input for digital-asset beta monitoring, source: International Monetary Fund 2022.
