One Stock Supplied Almost the Whole Gain
Monday's rebound was, in index terms, a single-stock event. Dangote Cement rose ₦128.90 to ₦1,469.90, and with 16.87 billion shares in issue that one move added roughly ₦2.17 trillion of market value, close to the entire ₦2.32 trillion increase in total capitalisation. The cement maker, at ₦24.80 trillion, now accounts for about 15% of the whole exchange, so a near-limit move in the stock sets the direction of the benchmark almost regardless of what the other 145 securities do. The session partly reversed the damage of Thursday and Friday, when the same stock's limit-down fall dragged the index to its weekly loss, and it left the benchmark 0.9% below the 20-session high of 254,762.81 set on November 4.
Support elsewhere was real but much smaller in index weight. Oando gained 8.46% to ₦35.90, Fidelity Bank rose 6.85% to ₦24.95 and Transcorp Power added 5.65% to ₦232.00, while Seplat Energy led trading by value without a price change. None of those moves carries the capitalisation to move the ASI on its own, which is why the headline gain overstates the breadth of buying behind it.
Breadth Tells a Weaker Story Than the Index
The gainers and losers table points the other way. Decliners outnumbered advancers by 34 to 22, a reversal of Friday's 31 gainers against 26 losers, and 90 stocks did not move at all. AXA Mansard topped the gainers at ₦12.95, just ahead of Sovereign Trust Insurance, up 9.74%, and Dangote Cement itself, while Thomas Wyatt, University Press and Fortis Global Insurance fell 9.62%, 8.70% and 7.38% respectively. A market in which the index rises 1.44% while most traded stocks fall is being carried by its largest constituent, and that concentration cuts both ways: the same weight that rebuilt ₦2.32 trillion of value on Monday removed a comparable sum the previous Thursday.
Trading activity at least broadened. Volume rose 21% on Friday to 448.68 million shares, value traded climbed 15% to ₦30.01 billion and deals increased 28% to 41,337, with Chams, Access Holdings and First HoldCo the most traded by volume after Chams. The recovery in turnover suggests investors used the week's opening session to rebuild positions cut during the two-day selloff, rather than the gain resting on a handful of crosses in one heavyweight stock.
The session therefore repaired the index level without repairing market breadth, and the distinction matters for what follows. Until advancers begin to outnumber decliners on up days, rallies of this shape remain hostage to Dangote Cement's next move, in either direction.
