I just got paid some dividends from an ETF that I own. However, that dividend is only about $4, which is sitting as cash in my brokerage account.

What's the best thing to do with this cash? It isn't even enough to pay the commission to buy more of the ETF.

I just got paid some dividends from an ETF that I own. It is only $4, which is sitting as cash in my brokerage account. I'm aware that this is a very tiny amount of money in the grand scheme of things, so this question is more for my curiosity's sake.

The ETF doesn't offer a DRIP option, but even if it did, it probably wouldn't meet the minimum amount needed for a commission-free purchase.

What's the best thing to do with this cash? Sit on it till I have more that I can use for trading down the road?
