No. There are several actions you can take if quitting your job is in the foreseeable future.
1. Leave it there and let it continue to grow even though you can or cannot contribute to it anymore. This depends on your employer.
1. Roll over to an IRA account. This is the best method because it allows you to continue contributing. Your money will grow more and faster. You just have to make sure your 401(K) provider transfers the funds to your IRA account and not sending a check to you.
3. Cash it out. I don't recommend this method since you'll have to pay a penalty fee and won't receive your money in full.
Whether you invest in stocks or not, having a 401(K) account is highly recommended. This would be your retirement funds.
