Switch ETF?

Hello everyone,

I have been saving the S&P since October 2021 $500 (+0,58 %) initially still in training and only since July 2022 with 350 € per month, which now results in a value of approx. 7,500 €.

Now I've been thinking about switching to the $CSPX (+0,25 %) as it is from iShares, has 10 times the fund volume, is fully replicated and has a TER of 0.07%.

in comparison:

$500 (+0,58 %) / $CSPX (+0,25 %)

Fund volume: 6.39 billion / 61.77 billion

Provider: Amundi / iShares

Replication: Synthetic / Complete

RATE: 0.15 % / 0.07 %

If you look at this breakdown, the iShares fund $CSPX (+0,25 %) from iShares is much better.

However, I'm not sure whether it's worth liquidating and switching the old ETF or simply stopping the savings plan and investing in the new ETF.

The new $CSPX (+0,25 %) would then be saved with a savings rate of €600 - €800 per month.

Please let me know your opinion or what you would do in this situation.

Greetings Tobi
