100% agree around following the Nasdaq (which has a higher volume traded than the ASX). I'd however note the ASX may not be trusting the US after market. I'm presuming larger players are aware of it and consider it in their bids/offers.

Yes 73.46 down to 64.48 is down 12%. The aftermarket close was 67.00 (down 8.8%) so the current 13% fall is following the main close, not the aftermarket close. The AUD to USD exchange rate is about 0.69 so that would put PLL around 97c on an exchange rate adjusted aftermarket close. I guess we will find out tonight whether the Nasdaq thinks 64.5, 67.0 or something else completely is an appropriate price.

My personal take is a lot of the PLL fall was following other big lithium companies in America down, particularly Albemarle. Albemarle's fall was triggered as CATL's sharp lithium pricing became known. CATL provided customers it was at risk of losing (or already losing) some sharp pricing in an attempt to retain them. If CATL lost them there's zero margin, so the offer provided was good. For the first couple of hours the knowledge of CATL's sharp lithium price reference was in the market, but not as much around it being to customers at risk of leaving or already switching to other suppliers. That info filtering out over the next few hours may have been behind the 7% increase from the low point to the after-market close. If this was the logic behind PLL's fall, I'd expect a bounce back on the US tonigh (and Tuesday's ASX to move following what the US listing does on Monday).
