Nigerian equities closed Friday at ₦162.16 trillion.

The All-Share Index rose 1.42%.

Trading volume declined 52.18% from the previous session.

The market-value increase does not represent fresh cash invested.
September 19, (THEWILL) – Nigerian stocks added ₦2.27 trillion in market value on Friday, September 18, even as trading volume fell by more than half, giving investors two different readings of the same session.
Equity market capitalisation increased from ₦159.89 trillion to ₦162.16 trillion, while the All-Share Index advanced 1.42% to 249,804.56 points, according to Nairametrics’ closing-market report.
Share prices rose overall, but the amount of trading behind those prices declined. For investors assessing the rally, both measures deserve attention.
Prices Rose as Fewer Shares Changed Hands
Approximately 526 million shares were traded, down 52.18% from the preceding session. The number of deals also declined, falling 18.11% to 44,239.
MTN Nigeria gained 9.20% to close at ₦890, while Wema Bank rose 9.03% to ₦32. Across the exchange, 36 securities advanced and 22 declined.
Those gains were sufficient to lift the overall market despite losses elsewhere. However, they do not establish that investors bought more shares or that every portfolio increased in value.
Market capitalisation reflects the prevailing price of outstanding shares, including shares that did not trade during the session.
A price increase can therefore add substantially to a company’s market value without an equivalent amount of money changing hands.

Friday’s increase should not be described as fresh deposits into the exchange or money raised by listed companies.
It represents a change in the value assigned to their equity.
Similarly, lower trading volume does not, on its own, establish declining investor confidence. The closing figures show what traded and at what prices, rather than why individual buyers and sellers acted.
For shareholders, the practical consideration extends beyond a rising index to how readily they can trade their particular holdings. A market can gain value while activity remains uneven across its constituent stocks.
Subsequent sessions will show if price gains spread to more companies and attract greater trading activity. Until then, Friday’s result establishes stronger equity valuations alongside a quieter trading session.
