End of Year Bonus - Dump into Roth?

I maxed out my 401(k) ($19,500) and family HSA ($7,300) this year. Up until about February of this year, I was also maxing out mine and my wife’s Roth ($500 per month apiece). So I still have about $11K that I can dump into the Roth prior to April 15 of next year for 2022, right? I am going to get back on track in January with bi-monthly contributions.

I will be getting a very nice annual bonus for 2022 sometime around March. I’m torn between buying $11K all at once, especially considering the roller coaster ride we’ve been on this year. I’m equally concerned about missing the compounding of this $11K over the next 20-25 years before retirement if I miss the window. My question is: should I dump all $11K into the Roths in March or should I put the money into my after-tax brokerage account that is heavily tilted towards cash equivalents (I use it for saving money for big purchases: vehicles, home improvements, etc.).

My fear is that I am used to dollar-cost averaging. I’d really hate dumping $11K in all at once and seeing several thousand of it disappear overnight in the event of a short-term selloff.

Thanks!

Put it all in a money market or buy individual issue T-bills. Very safe compared to stocks.

NO! Put all you can into the two Roth IRAs, as soon as you can! If you go into CDs, the “tax-free-forever” opportunity for this money will be lost and you can NEVER recover that lost opportunity for that particular money. If you put it into a low-cost stock index fund, it will be perfectly safe. If you go with CDs, you WILL lose money because the interest from the taxable CDs will NEVER keep up with inflation, so your actual CD gains will be negative (a loss). Sure you will gain in numbers of dollars, but loose in the buying power of your retirement money. Many people that have a fear of loss NEVER even consider the loss on CDs due to inflation.
