Let's examine two mutual funds. One is an index fund that charges a 0.1% annual management fee. The other is an actively managed fund, that charges a 1% management fee. In addition, relative to the index fund, the active fund incurs an additional 0.5% extra trading costs. 0.2% extra performance loss due to holding a 5% average cash position, and an additional 0.75% tax drag in after-tax net returns for the average investor, due to its high turnover and short term gain capitalization. Under these conditions, by how much must the active fund's raw investment return (before any fees/costs) beat the performance of the benchmark market index, in order for its investors to be at least as well-off investing in the active fund as in the index fund? Enter answer in percents, to two decimal places
