What are people doing as far as cash positions? Are you fully invested? Raising cash, and if so how much (5%, 10%, 20%, more)?

The buffet indicator (normally he sells at 120%) is now at 220%. Berkshire has $320 billion in cash and has been a net seller over the last 2 years. Should we all be raising cash for whatever correction is coming? Especially if you are 10 or less years from retirement.
