OP - do you have other sources of income for retirement? If so, what percentage of your expenses do you cover with those?
Another key question - what's your NEED to take that level of risk? Do you need to take on that much risk to meet your retirement goals, legacy goals, etc?
If you're not close to 100% coverage on your expenses, there is no way on earth I'd be 100% stocks. What would you do, for instance, if we get to 50+% down on equities? Sell at 50% down to cover some of your expenses? If so..yikes.
I'm (late 50s, DW mid 60s) at ~25% equities and am looking for every chance I get to sell what we do have in equities at this point and move mostly to CDs and MYGAs. I spend a good part of every day following some pretty well respected financial experts and it's near universal among them that this market is headed a LOT lower - as in S&P 3,600 or even lower. (I've actually heard estimates from well known, very credible folks of SPX 3K all the way down to SPX 1,800).
There was a poll here recently that indicated (if I remember right) roughly 1/3 of ER members have a government pension, 1/3 have a corporate pension and 1/3 have notta (that'd include me and DW). I strongly suspect that influences how much risk ER members are willing to take with heavy stock allocations. But those of us who do not have those other sources of income tend to be much more conservative and have significantly lower allocations, FWIW..at least that's my casual observation.
I'd suggest thinking long and hard about how you'd feel if the wealth you've accumulated at this point drops another 30% (SPX 3K) or more from these levels. We're already down ~17% on the S&P for the year. And how you'd feel if we got to SPX 2K - roughly another 50% down from these levels. If you have any significant wealth accumulated, that's a big number in terms of $$s "lost" and potentially a very long time (more than a decade in all likelihood) to get back to "even"..
JMHO, but I don't know a single professional financial advisor who would recommend a client in their 60s to be 100% stocks. Asset Allocation is what you want to / should focus on - and even though bond funds have been hammered pretty good YTD also, all your eggs in the equities basket is not likely to end well.
