BP stock ends the day 3.06 percent lower at the close on the NYSE

At the close on September 21, 2026, BP stock finished down 3.06 percent on the NYSE, underperforming the broader energy sector. The move came as oil prices retreated and UK energy shares weakened, with BP also falling in London trading earlier in the day.

BP stock closed at USD 43.20 on the NYSE on September 21, 2026, a decline of 3.06 percent from the prior close in regular trading. Compared with the broader Energy - Fossil Fuels sector, which fell about 2.13 percent the same day, BP underperformed its sector benchmark.

September 21, 2026 in numbers

BP p.l.c. (ISIN GB0007980591, NYSE: BP) opened the session at around USD 44.60 on the NYSE before slipping through the day to an intraday low near USD 43.00, with the closing price of USD 43.20 sitting toward the lower end of the daily range. The shares ended the session more than USD 5 below their 52-week high of roughly USD 48.27, leaving BP further off its recent peak. In London, BP’s home-market listing declined about 2.8 percent by the close at roughly 11:35 a.m. ET, while Shell fell 1.4 percent over the same period, a move that Reuters linked to retreating oil prices.

As TradingKey reported in its market-movers summary for September 21, 2026, BP’s 3.06 percent drop came against a weaker backdrop for fossil-fuel energy stocks overall. Per NYSE data reproduced by major quote services, BP’s U.S.-listed shares traded several million shares during the session, broadly in line with recent averages, indicating the decline occurred on normal liquidity rather than an exceptional volume spike.

After the bell and the next session

After the close on September 21, 2026, BP’s ADRs showed only modest price indications in early after-hours trading on the NYSE, with no clearly substantiated extended-hours print standing out by 4:30 p.m. ET. A broader UK market report from Reuters highlighted that energy stocks weakened as oil prices retreated, a theme that may continue to influence BP shares after the bell. The next U.S. trading day falls on September 22, 2026, when investors will watch crude benchmarks and sector peers for further signals, as well as any new company or regulatory developments affecting large integrated oil groups.
