Seplat Energy Plc started the week strongly as excitement swept through the Nigerian Exchange (NGX) on Monday, October 6.

Seplat Shares Soar
By midday, the stock surged 10 % to ₦5,917.20, jumping from ₦5,379.30, signalling renewed investor confidence.
Investors poured roughly ₦1.62 billion into Seplat shares, pushing it to the top of the NGX gainers’ chart.
London Listing Gap
Meanwhile, London attention focused on Seplat’s shares, which opened at £3.09, about ₦6,084, higher than the Nigerian price.
This difference created a potential arbitrage opportunity for traders operating across both markets.

Cross-listed stocks often experience such gaps as investors respond differently to liquidity, sentiment, and currency changes in each market.
As trading continued, Seplat’s London price slipped 3.55 % to £2.98, narrowing the gap and briefly turning it negative.
Analysts said the movement reflected typical trading behaviour rather than any mispricing between the two exchanges.
Settlement Differences Matter
Differences in settlement cycles added to the short-term gap: NGX clears on T+3, while LSE operates on T+2.
Seplat’s sharp NGX rally highlighted how local investor enthusiasm can ripple across global markets, connecting Lagos and London.
