ADS market

"ADS, each representing eight ordinary shares"

Ads are paid promotional messages a company places across media — online, on TV, in print, or on social platforms — to attract customers, explain products, or shape public perception. For investors, ads matter because they drive sales growth, affect how much a company must spend to win customers, and influence brand strength and long-term value. Ads can also create regulatory or reputational risk if claims are misleading, which can affect profits and stock price.
