is it correct that if it had not equitized with the futures contracts, the benchmark would be the Rf rate (because the market neutral strategy has no systematic risk?)

jmh530

yes , that is correct , the mean return for a market neutral strategy should be comparable to the risk free rate, generally. Any additional alpha would be the return to the manager's skill
