Chapel Hill Denham Securities Limited has emerged as the top-performing brokerage firm on the Nigerian Exchange (NGX) for the week ending October 3, 2025, dominating both value and volume of trades, according to a recent NGX Broker Performance Report.
The firm executed transactions worth N53.82 billion and traded 10.97 billion units, accounting for 23.28 percent of the total market value and 65.26 percent of total market volume.
Its performance widened the market share gap with competitors. First Securities Brokers Limited followed with N33.46 billion (14.47%) in trades and 1.57 billion units (9.36%), while Stanbic IBTC Stockbrokers Limited placed third with N30.67 billion (13.27%) and 688 million units (4.09%).
Overall, the top ten brokerage firms handled N172.26 billion in trade value, representing 74.51 percent of the total market. They also executed 88.13 percent of all trades, showing rising concentration within the top tier of market operators.
CardinalStone Securities, Afrinvest Securities, and Morgan Capital Securities also appeared among the top performers by volume, while Arthur Steven Asset Management and Cordros Securities recorded strong showings by value.
Analysts attributed Chapel Hill’s exceptional dominance to large institutional orders from foreign and domestic funds. “The concentration suggests Chapel Hill Denham is executing major mandates, likely from portfolio investors or fund managers,” a Lagos-based analyst said.
The firm’s command of more than half of the total traded units has been described as a rare event in the NGX, reflecting growing institutional confidence in its execution capacity.
As the final quarter of 2025 begins, market watchers are monitoring whether rivals like First Securities Brokers and Stanbic IBTC can narrow the gap. Analysts say firms with solid research, liquidity access, and cross-border capabilities will remain best positioned in Nigeria’s evolving equities market.
