Hello,
A problem was introduced in March where special dividends that have the same ex-date and pay-date are never added to the cash affecting overall performance. These type of dividends are used by S&P with mergers for example. On the day after the last day of trading a special dividend is paid that represents what you got for your shares (usually cash or the market value of the acquirer’s stock).
Depending on your system this can severely understate your simulation results. We’ll have a fix shortly
Sorry about this.
