I have 500k in my checking account. Not good in stock picking, and neither consider myself lucky. What is the best autopilot mode so that this wealth can be preserved? I want some decent growth, but would prioritize wealth preservation over drastic returns. Would you recommend Target Date Funds over VTI or otherwise? I am just looking for a max three stocks or funds which will not need any intervention from my end. Basically invest and forget.
