Stock Market Update

[BRIEFING.COM] The S&P 500 (-0.2%), Nasdaq Composite (-0.6%), and DJIA (+0.1%) are mixed just after midday.

Alphabet (GOOG 397.56, +4.24, +1.08%) is a mega-cap standout today, trading to new all-time highs despite a relative dearth of corporate news.

However, it is worth noting that Berkshire Hathaway Inc. (BRK-B 484.86, +2.16, +0.45%)  disclosed a new position in the company in its 13F filing on Friday.

The stock is the best-performing "magnificent seven" name so far in 2026, rising 26.9% year-to-date. However, May has seen more muted gains, with the stock up 4.2% month-to-date.

The rest of the mega-cap complex is largely under pressure today, with the Vanguard Mega Cap Growth ETF 0.6% lower.
