Southern Co stock (US8425871071): Insider sale and price drop put focus on recent volatility

Southern Co shares on the NYSE have come under pressure after a 3.3% decline to around USD 89, just as a company comptroller reported a small insider share sale, keeping attention on the U.S. utility's near-term dynamics.

Southern Co shares on the New York Stock Exchange traded around the high-USD 80s after falling 3.3% to USD 89.03 on 06/01/2026, according to GuruFocus citing market data as of that date, keeping the Atlanta-based U.S. utility in focus for its recent price volatility.

On the same day, a Form 4 filing with the U.S. Securities and Exchange Commission reported that Southern Company comptroller Matthew M. Kim completed an open-market sale of 100 common shares at USD 91.16 per share on 06/01/2026, a modest transaction relative to his remaining stake.

The filing shows that after the sale Kim directly held 6,688 Southern Company shares and indirectly owned 1,212.1903 shares through a 401(k) plan, suggesting the move represented portfolio fine-tuning rather than a substantial change in exposure to the U.S. electric and gas utility.

Southern Co, which is a component of major U.S. utility benchmarks and trades under ticker SO on the NYSE, continues to attract attention from domestic investors given its role in the regulated power markets of the United States and the visibility of its dividend track record.

The stock traded at USD 89.03 on 06/01/2026 on the NYSE, according to GuruFocus as of 06/01/2026, after the latest daily move highlighted how interest-rate expectations and sector sentiment continue to influence U.S. regulated utilities.
