NGX launches new thresholds for share price changes
The Nigerian Exchange Limited (NGX) has introduced new rules that will significantly alter how share prices move on the exchange by setting minimum trading volume thresholds before prices can change\.
The effective date is also expected to be communicated by the exchange in due course.
Confirming the changes via its new Rulebook seen by Nairametrics, the NGX stated: “Price Movements: the minimum quantity of equities traded that will change the published price of an equity security shall be as follows: (A) Group A: Ten Thousand (10,000) units; (B) Group B: Fifty Thousand (50,000) units and (C) Group C: One Hundred Thousand (100,000) units.”
Under the new rules: stocks trading at N1,000 and above will require a minimum of 10,000 shares to be traded before a price movement can occur.
Stocks trading at N500 and below N1,000 will require a minimum of 50,000 shares to trigger a price change.
Stocks trading at below N500 will require a minimum of 100,000 shares to move the market price.
The development marks a significant shift in the exchange’s price discovery mechanism and is expected to affect trading strategies, particularly in stocks where relatively small volumes have historically been sufficient to move prices.
Market participants say the move could help improve price stability and reduce the impact of low-volume transactions on share prices, especially in highly priced equities. However, some traders are already expressing concerns that the new thresholds could reduce price responsiveness in less liquid stocks.
The policy comes amid heightened regulatory attention on market integrity, liquidity, and price formation as the Nigerian capital market continues to attract increased retail and institutional participation.
The reform comes amid broader discussions around market liquidity, free-float requirements, investor participation, and efforts to align the Nigerian capital market with evolving global standards.
The proposed amendments form part of changes to Part XI of the NGX Trading License Holders’ Rules dealing with pricing methodology and price movements.
The framework introduces a three-tier classification system for equities based on share prices and establishes corresponding minimum trading quantities required before market prices can change.
Market operators expect the changes to improve liquidity and price responsiveness in high-priced equities while supporting more efficient valuation across the Exchange.
The NGX is yet to formally communicate the implementation date, although market participants expect further guidance and operational details to be released in the coming days.
As stakeholders await formal implementation, attention will remain focused on whether the new pricing methodology succeeds in improving market efficiency without compromising stability or investor confidence.
