If I short an ETF stock, how does it work from the cost and tax perspective?
Do I get charged ETF expense ratio? (does not make sense to me)
If underlying stocks issue dividends, am I charged them? (makes sense)
What happens if ETF rebalances its structure - would I be required to counter that rebalancing by buying or selling individual stocks after closing my ETF short? If yes, what would this look like in 1099-B or other tax forms? (seems too complicated to be likely)
I am primarily interested in stock index ETFs but if there are different answers to other types of ETFs (except inverted ones, of course), I'd like to know them as well.
UPD: Corrected that #1 is about ETF expense ratio, commission was not a correct term.
