Your have the following data on different rates for the same maturity of 1.5 years. However the rates are quoted on different basis and compounding frequencies:

• Continuously compounded rate: 2% per annum (i.e. annualized)
• Continuously compounded rate: 3% over the holding period (i.e. over 1.5 years)
• Annually compounded rate: 2.1% per annum
• semi-annually compounded rate: 2.01% per annum

You are looking for an arbitrage opportunity. Is there any mis-pricing here and if so how would you execute the arbitrage?
