The investment account does not accrue interest, but you may receive dividends from your ETFs. These dividends will be automatically transferred back into your HSA cash account, where you can choose to reinvest them if desired.
Please note that dividends issued after your statement's generation date may not appear on your statement, as it reflects activities up to the end of the month. However, you may still receive dividends after that date.
Your cash account is interest-bearing and requires no action from you.
