Dividend yield measures the annual dividend income from a share relative to its current market price. It is calculated as annual dividend per share divided by share price and is usually expressed as a percentage. The purpose is to provide an income-based return metric that allows investors to compare shares, funds, or sectors on a like-for-like basis in terms of dividend income generated per unit of price paid. This is particularly relevant for income-focused investors assessing whether a share offers attractive income relative to alternatives, while recognising that dividend yield is not the same as total return because it excludes capital gains or losses. Option A relates more to retention and reinvestment, which is assessed using payout ratios and earnings coverage rather than dividend yield alone. Option B is tax-planning related and not the core purpose of the metric. Option D is not what dividend yield measures; a high yield can reflect a falling share price or expectations of dividend cuts as well as growth. The key exam point is comparability of dividend income return.

* Modern Portfolio Theory (MPT) and the Efficient Frontier
* The efficient frontier represents portfolios that offer the highest return for a given level of risk.
* Portfolios below the frontier are inefficient because they provide lower returns for the same level of risk or higher risk for the same level of return.
* Why the Answer is D
* Portfolios below the efficient frontier are suboptimal; the investor is not maximizing return relative to the risk taken.

Commodities (e.g., gold, oil, agricultural products) are not covered by insider dealing regulations, as they are physical assets rather than securities.
Why Are Commodities Exempt?
Insider trading laws apply to securities markets, not physical goods.
Price movements in commodities are driven by supply and demand, not company disclosures.
Regulation of Commodities:
While insider trading rules don't apply, market manipulation laws still govern commodities (e.g., FCA MAR rules).
