@user1ca81461c2154a1a The unhedged TIPS also maps the currency fluctuations from EUR to USD. The signals do not match. The hedged one tracks the US original quite accurately. Such details are important!
@Epi Yes, the unhedged one reflects currency fluctuations when you convert it from the original USD to EUR. This could lead to errors in the signal if the USD/EUR fluctuates strongly. But you could also simply use the original USD as a signal without converting to EUR?
@user1ca81461c2154a1a Correct. That would be the most accurate: look at the S&P500 and TIPS directly in the original. Hedged ETFs are an easy way for investors in Germany.
