Oil majors lose ground

Reuters said on September 21, 2026, that BP and Shell each dipped near 1 percent as oil prices retreated, giving investors a clear same-day trading cue for the London-listed oil major.

Trading Economics showed BP among the biggest losers in the FTSE 100 on September 21, 2026, with a decline of 1.74 percent, while the index itself was higher on the session.

Valuation stays central

Yahoo Finance put BP's previous close at USD 45.42, so the September 18, 2026 close of USD 44.58 was USD 0.84 lower and equal to a 1.85 percent drop. The same quote page also listed intraday volume at 11,215,670 shares and an intraday market cap of USD 114.812 billion.

For investors, the numbers keep the focus on cash flow and commodity sensitivity rather than a new corporate event: the stock was still trading near the middle of its 52-week band, not at the low end and not near the peak.
