Rich, I’m a little late to the discussion, so at the risk of being somewhat redundant, as other people have mentioned aspects of this:
Your allocation of investments between stocks, bonds, and other things is indeed something to consider. And I won’t get into whether a 60-40% stocks vs bonds, or whatever, is the optimal ratio. I aim for 70% stocks, myself but that’s just me. And which accounts hold which assets can make a difference tax-wise, whether in IRA, 401(k) and other pre-tax retirement accounts, or in taxable investment accounts, or Roths, can make a difference too.
However your target allocation breaks down, don’t wait until the year you retire to get there, and have to diversify and reallocate and sell things you have to sell when the market is bad. Especially if you’ve got a retirement plan full of your employer company’s stock. That’s something to plan around and diversify to a reasonable level. If bad events happen to your company, that’s a double threat to your job and your investment portfolio.
I specifically worked and made adjustments to make my portfolio look the way I wanted it to look in retirement, 2-5 years ahead of time, doing it gradually. Prior to that time I was more heavily invested in stocks.
This also allows you to have a realistic view of how much current income your portfolio will produce, and how that will affect your retirement budget. Also keep in mind that current income from dividends and interest let you sit through market dips and dives without having to sell when you don’t want to.
In any case, good luck. I retired at 62, took Social Security at that time, and have made other decisions that smart people here disagree with, with very few regrets. It has worked out well. Bull markets have a way of paving over imperfections in the path you take.
