Title say’s it all. Also if stocks with Target are better, can I leave my 401K with Target and make another employee sponsored one with another company? That would be two 401K.
From what I remember when I left a job with a 401K, you can let it stay as is - you just won't be making automatic contributions via payroll deductions or getting the employer match. Or you can roll it over to an IRA without incurring any tax penalties.
This isn’t true, if you’ve made an account with the 401k provider then you still maintain agency over your investment portfolio after leaving your job.
I wouldn’t say leaving it is “bad”, but it may not be as advantageous as rolling it into your new employer’s plan.
