Did you watch that Shack video linked above?
Being out of the market for just a few key days in cash can seriously dent your long term wealth; if you are about to retire I can see the value in reducing equity exposure but I believe you are some years away from retiring so meddling as you are will likely damage your long term prospects ... but maybe your market timing moves will work out ... who knows ... all I know is its very difficult to call the markets; full time teams of professionals fail at it so I have given up trying to outsmart them ... I have tried this myself with mixed results ... I called the dot com crash and did well but tried to get smart during the covid crash and was too slow to get back in to some cost ... since then I have vowed to be a passive investor.
