The Nigerian stock market recorded a gain of N3.2 trillion for investors during the week, attributed to renewed interest in sectors such as banking, telecommunications, and oil and gas, according to Premium Times Business.

In June 2026, the market capitalization of Nigeria's largest listed companies, categorized as SWOOT (Stocks Worth Over One Trillion Naira), decreased by N11.97 trillion month-on-month. This decline was attributed to profit-taking and foreign exchange pressures, leading to a significant sell-off in the stock market, according to Nairametrics.

Foreign investors' transactions on the Nigerian Exchange (NGX) fell by 25.90% month-on-month in May 2026, totaling N183.61 billion, down from N247.78 billion in April. This decline marks the worst performance for foreign investor participation in 2026, despite overall market activity reaching its highest monthly level of the year, according to Nairametrics.

On June 24, 2026, the Nigerian equities market experienced its largest single-day decline of the year, with a loss of N3.64 trillion in investor wealth. This drop was primarily driven by profit-taking in major cement and power stocks, including BUA Cement, Dangote Cement, and Geregu, which overshadowed the previous days' buying momentum and halted the market's recovery efforts.

The Nigerian stock market experienced a decline of N3.6 trillion, reversing two consecutive days of gains. This drop was attributed to widespread profit-taking activities, particularly in BUA Cement, which saw a 10 percent decrease in its stock value. Additionally, 37 other stocks were affected, contributing to the overall market downturn, according to ThisDay Live.

The naira experienced its most significant daily decline since April, closing at N1,389 per dollar in the official foreign exchange market on June 24, 2026, according to Nairametrics.
