The Nigerian stock market experienced a dramatic downturn, with investors losing N3.8 trillion in just four trading sessions. This significant loss coincided with a recent visit by President Bola Ahmed Tinubu to the Nigerian Exchange Limited (NGX).

Data from the NGX indicates that the market began to decline sharply from Tuesday to Friday, with a staggering loss of N2.932 trillion recorded on the first two days alone. The downturn continued on Thursday and Friday, with losses of N613 billion and N257 billion, respectively. By the end of the trading week, the market capitalization had fallen to N156.623 trillion, down from N156.880 trillion.

The All-Share Index (ASI) also reflected this bearish trend, dropping 398.18 points or 0.16 percent, to close at 242,619.20. The decline was largely attributed to sell-offs in several key stocks, including Fortis Global Insurance, Omatek Ventures, John Holt, RT Briscoe, and Dangote Sugar, among others. Notably, Fortis Global Insurance led the decline with a 9.31 percent drop.

In contrast, International Energy Insurance emerged as a rare gainer, increasing by 9.92 percent to settle at N5.32. Overall, market activity weakened significantly on Friday, with total trading volume plummeting by 66.64 percent to 1.41 billion shares, valued at N45.31 billion across 39,134 transactions. Fortis Global Insurance dominated trading volume, accounting for 61.83 percent of total shares traded, with 874.08 million shares changing hands. MTN Nigeria topped the value traded, with N31.37 billion, making up 69.24 percent of the total value on that day.

The downturn in the market follows a visit on August 6, 2026, by the NGX Board and Management, led by Chairman Dr. Umaru Kwairanga and Group Managing Director Temi Popoola, to President Tinubu. During this visit, the President praised the ongoing reforms at the NGX and assured stakeholders that the Nigerian National Petroleum Company Limited would be listed on the stock market, a move that was anticipated to boost investor confidence.

However, the immediate aftermath of the visit has raised concerns among investors, as the stock market's performance has not reflected the optimism expected from such high-level engagements. The significant losses over the week have prompted discussions about the underlying factors affecting market stability and investor sentiment in Nigeria.
