As Nigeria's stock market enters the second half of 2026 in the grip of a sharp pullback that has stripped more than 16,500 points off the All-Share Index since its record high in May, new NGX figures lay bare which sectors have actually built wealth for investors.
NGX data as of the close of trading on Friday, June 19, puts the benchmark All-Share Index at a year-to-date return of +51.62%, a showing that stands out by any global yardstick.
Yet that headline number hides a dramatic split beneath the surface. Oil & Gas and Industrial Goods have handed investors returns that more than double the market average, while Banking and Insurance have lagged well behind.
What the data is saying
Ranking every NGX sectoral and key index by year-to-date performance as at June 19, 2026 lays out a clearly divided market: the outperformers and the underperformers.
Outperformers: year-to-date returns above the ASI benchmark of +51.62%
Heading the table is the NGX Oil/Gas Index, up +111.13% so far this year, a return so far ahead of the benchmark that it sits in a league of its own.
Two oil majors, Aradel Holdings Plc and Seplat Energy Plc, did most of the heavy lifting behind that performance, with Geregu Power standing out as the sole laggard.
Next in line is the NGX Industrial Goods Index at +95.79%, nearly doubling investor money in less than six months. Cement giants and manufacturing names powered the gain, lifted by expectations of higher infrastructure spending and the slow steadying of input costs.
The NGX Premium Index at +70.32% captures the year's flight to quality. The exchange's biggest and most liquid stocks, the ones that clear the tougher Premium Board listing standards, beat the ASI by close to 19 percentage points.
This is the index institutional investors at home and abroad watch most closely, and its strength confirms that the year's rally was no mere speculation. It was rooted in the market's most fundamentally solid names.
The NGX Lotus II Index at +85.15%, which tracks Sharia-compliant equities, completes the leading pack. Its return, comfortably above the benchmark, owes much to its overlap with the energy and commodity-linked stocks that fuelled the wider rally.
Filling out the outperformer bracket, the NGX Commodity Index at +61.29%, NGX Pension Index at +59.57%, NGX Pension Broad Index at +59.06%, and NGX Growth Index at +55.07% all finished ahead of the ASI benchmark.
More insights
With the standout gains from Aradel Holdings (+161%) and Seplat Energy (+95.6%), the sector's strength turns out to be heavily concentrated in just two stocks.
Aradel Holdings' remarkable run has been the chief engine of the sector's performance, with Seplat Energy Plc close behind.
Aradel closed last Friday, June 19, 2026 at N1,750.00 per share, a 4.8% rise on its previous close of N1,670.00. Having opened the year at N670.00, the stock has since added 161%, placing it eighth on the NGX for year-to-date performance.
Seplat ended last Friday at N11,363.90 per share. From a year-opening price of N5,809.00, it has gained 95.6%, ranking 29th on the NGX year-to-date.
Conoil Plc closed last Friday at N210.00 per share, up from its opening price of N187.20, a 12.2% year-to-date gain that ranks it 74th on the NGX.
Oando Plc finished last Friday at N46.00 per share, up from N40.20 at the start of the year, a 14.4% gain that places it 73rd on the NGX year-to-date.
Eterna Oil closed last Friday at N30.80 per share, up from its opening price of N28.50, an 8.07% year-to-date gain that ranks it 81st on the NGX.
Geregu is the lone underperformer in the sector, shedding 10.7% from its N1,141.50 year-opening price to last trade at N1,019.30 per share, ranking 118th on the NGX year-to-date.
An average investor holding an equally weighted basket of the six oil and gas stocks from the start of 2026 would have pocketed a return of roughly 46.8% by June 19, 2026.
What you should know
Banking and consumer goods have both fallen short over the review period.
The NGX Banking Index at +35.77% trailed the ASI by about 16 percentage points, a glaring shortfall for a sector that leads NGX trading volumes and features in nearly every investor's portfolio.
The banking sector's lag behind the broader market ranks among the most surprising twists of 2026, especially given that FUGAZ earnings have largely held up well.
Part of the answer lies in valuation, with banks already priced for hefty growth coming into the year, and part lies in the CBN's fresh regulatory stance, which set off June's correction alongside a wave of profit-taking.
Value-leaning banking names and high-dividend payers, captured by the NGX AFR Bank Value Index at +41.65% and the NGX AFR Dividend Yield Index at +40.33%, both finished below the benchmark.
The NGX CG Index at +40.80% and the NGX Consumer Goods Index at +18.14% round out the underperformers among the productive-sector indices. Consumer goods firms have wrestled with squeezed margins, high input costs, and weak household spending power right through 2026.
At +18.14%, consumer goods investors have earned less than a third of what oil and gas investors banked on the same exchange over the same stretch. That 93-percentage-point gulf between the two sectors stands as one of the defining features of Nigeria's investment landscape in H1 2026.
The NGX Insurance Index at -1.75% year-to-date is the only major productive-sector index sitting in negative price-return territory in 2026. Insurance investors have done worse than simply trail the field. On a price-return basis, they have lost money in a year when the benchmark is up more than 50%.
Slim underwriting margins, low premium penetration, ongoing capital adequacy strains, and a sector still digesting the new IFRS 17 accounting standard have kept institutional money largely away from insurance stocks.
As the market closes in on the midpoint of 2026, the central question for sector positioning is whether the Oil & Gas and Industrial Goods lead can hold, or whether mean reversion, already showing up in the June correction, will close the gap with the trailing sectors.
