Why would emerging markets follow a US market trend attributed to news of a covid vaccine progression?
This is a worldwide pandemic that effects consumer confidence and discretionary at every level. Good news in that regard effects all markets. Clearly Luckin coffee is directly tied to consumer confidence and spending and should react accordingly to news affiliated to their industry regardless if they are trading in OTC land, are a Chinese company trading on a US exchange, or haven’t provided audited numbers as of yet.
I’m not correlating an overall US market move based on solely US indicators to a move in Luckin coffee share price, although at times it will move with sectors within the market. I am correlating a positive news covid related pr that spiked the US markets, particularly equities tied to a retail reopen trade, which should have an equally positive reaction to all markets globally with regards to positive vaccine progression and economic reopening in all countries.
