Stock Market Update

[BRIEFING.COM] The stock market opened in a mixed fashion this morning, though a significant gain in Alphabet (GOOG 293.09, +16.11, +5.82%) keeps the Nasdaq Composite (+0.4%) and S&P 500 (+0.2%) above their baselines, while broader-market weakness keeps the DJIA (-0.1%) slightly lower. 

Only four S&P 500 sectors trade higher, with Alphabet's gain putting the communication services sector (+2.9%) far ahead this morning. Alphabet's gain comes after Berkshire Hathaway Inc. (BRK-B 507.63, -1.31, -0.26%) revealed a new $4.9 billion stake in the company. 

Meanwhile, the utilities sector (+0.8%) holds a solid gain, while the health care sector (+0.3%) looks to continue an impressive run this month. 

Early strength in Tesla (TSLA 415.81, +11.46, +2.83%) nudged the consumer discretionary sector (+0.1%) into positive territory after opening with a loss. 

Losses are modest, with several sectors now sitting on their flat lines. Only the energy sector (-0.6%) holds a loss of 0.5% or wider.
