Which statement best describes pure arbitrage in financial markets?

Pure arbitrage is earning a risk-free profit with no net outlay by exploiting a price difference between equivalent assets. Other strategies like speculation, short selling on a view, or borrowing to buy riskier assets all carry risk, so they are not arbitrage.

  3. CHolding a diversified portfolio to eliminate specific risk
  4. DBorrowing at a low rate to invest in a higher-yielding but riskier bond
