I have some SPY for many years and it has gone up since then.
I noticed that the fees are much higher than the VOO which is also an ETF for the SP500.
Both ETF's hold the same underlying SP500 stocks.
So, can I sell my SPY and then buy the equivalent VOO?
I found the following keywords but no answers:
1) substantially identical
2) wash sale
3) creation redemption (using etf arbitrage, in theory one could redeem and then create rather than buy and sell)
