Well your initial post sound like you wanted to hide your money from the crash, then move it back after the crash to get the big gains, like I did last year. That would mean reallocating to the safe / low growth options you have within your 401k plan.
I almost said the same thing he did. If you don’t already know that withdrawal from 401k taxes and penalizes you it shows a big lack of understanding what you’re doing. With lack of understanding you can severely fuck yourself and there are no takesie backsies in this kind of stuff.
You can’t put 401k in your wallet to put to use unless you’re at the right age. You CAN put it to use by reallocating, waiting, then moving it back when/if the big dip happens. I do not recommend it though. I almost never touch my 401k allocations. I feel like I got very lucky with the supply chain knowledge I had and the lack of the US media in reporting about the virus in a timely manner. We knew about this disease months before the general public. We knew about supply chain complete cutoff months before the general public. If they decided to play the virus off in the media instead of amplifying it...I would have fucked myself out of probably 5-10% of gains (a shitload of money 25 years from now when retiring...compounding interest) On the flipside I felt like when the news hit we would crash a lot more than that if they amplified it, so I took the bet.
It was risky but I knew exactly what I was doing. You thinking you could cash out and then just put it back in when the dip happens doesn’t seem you know it doesn’t work like that. You also have a limit on how much you can put in each year. So let’s say you said fuck it and cashed it out anyways and you had $100k in there. You end up losing 30-40% right off the bat due to taxes and early withdrawal penalties. So you’ve got $60-70k in cash now...the dip happens and you try to buy back in...oops you can only put in $19.5k a year. Now you only have $19.5k in there...$40k in cash you can’t put in there until next year (and only $19.5k again) ALL that cash just completely missed the big gains on the rise back up. You just severely fucked yourself and missed out on $30-40k in gains on your original $100k that you should’ve just reallocated. So now in cash and 401k you have $60k total instead of $130k in the 401k...AND you’ll be missing out on $10s or $100s of thousands in compounding interest over the lifetime of that 401k now.
I suggest just leaving it alone.
