I'm 25M and recently opened my Roth IRA. I just invested $1,500 in VOO to get started for the long term.
While looking through my dividend distribution settings on Fidelity, I saw options to either
"Reinvest in security" or "Pay to cash'
As someone tocusing on long-term compound growth, which option is best for VOO dividends in a Roth IRA?
• Is enabling DRIP (Reinvest in security) the standard way to maximize compounding over time?
• Are there any reasons someone would choose
"Pay to cash" instead?
