Added an option for setting the long-term performance of global stocks.
Since the majority of an insurance company’s incomes are from investment gains in global stocks, the presence of this option allows the user to tailor the profitability of insurance companies.
We have also improved the simulation model - global stock returns will decrease over time, especially when a company’s market cap has grown to a very large size, to reflect the fact that it is increasingly difficult to make profits as markets become saturated.
