I think there could be two reasons behind this. One is some great policies framed by the existing government because they wanted to clean the slate before the US Election in coming November. There was immediate action upon policies to boost economy. Second is that everything could merely be framed. Fed might have ensured that there is enough money in the market until end of the year and once elections are done Economy would show it's real colors. Because no one can digest the fact that the world is under a complete lockdown and we haven't had another black Monday until now.
