i recently study on investment and bump into a video on validating if an ETF is overvalued or undervalued.
In summary, it is best to buy an ETF if the current market price is lower than the Net asset value (NAV) of the ETF.
And i went to check on all the ETF in my SA portfolio, other than KWEB, the rest are overvalued if compared with their respective NAV.
Does that mean i need to sell all and wait for it to drop to the reasonable market price that matches/lower than the NAV?
I believe you mean trading at a premium or discount not overvalued or undervalued. It is normal for etf to trade at premium or discount of it NAV, as it is traded like a normal share.

Same thing with stock with high P/E , trailing could be high but forward P/E might be lower.
