💎 The Casablanca Stock Exchange has announced its annual revision of the MASI20 index, the benchmark for Morocco’s most liquid blue-chip stocks. Effective October 7, 2025, four new companies will join the index:

• Crédit du Maroc

• CMGP Group

• Jet Contractors

• Sonasid

These entries will replace Managem, Mutandis, CIH Bank, and HPS, in line with the index methodology, which prioritizes free-float market capitalization and trading liquidity.

🔎 What is the MASI20?

The MASI20, launched in December 2019, is designed as a barometer of the Moroccan equity market. It reflects the performance of the 20 largest and most liquid listed companies and serves as a benchmark for both domestic and international institutional investors. Selection is based on:

• An initial universe of 40 major free-float companies

• Criteria of liquidity (trading volumes and frequency)

• A prudential capping mechanism aligned with international standards and UCITS (OPCVM) requirements

📈 Why this matters for investors:

• The revision ensures that the index remains representative of Morocco’s market structure, covering major sectors of the economy.

• For foreign investors, the MASI20 is often the entry point for exposure to Moroccan equities, as it offers:

• Liquidity (ease of entering/exiting positions)

• Diversification across leading sectors (banking, telecoms, construction, energy, industry)

• Transparency, since revisions are systematic and aligned with global best practices

• Funds and ETFs benchmarked to the MASI20 will rebalance accordingly, which could generate short-term flows into the newly added stocks.

⸻

👉 In short: The MASI20 acts as Morocco’s blue-chip index, and its revision strengthens market efficiency, enhances Morocco’s appeal for international capital, and provides foreign investors with a more accurate benchmark for allocating funds to Casablanca-listed equities.
