There will be no stimulus deal before the election- Pelosi won't hand that card on a golden plate to Trump before the election, period!
Nov 3rd:
If Trump wins- continuation of bubble to a new ATH
If Biden wins- election will be contested due to mail-in voting fraud and riots will engulf everywhere until the situation gets under control.
This is only one of the possible scenarios, take your own decision and risks or stay in cash until it's clear.
