higher price; price rise
Used in financial contexts to refer to a price that is higher than a previous or reference price, often in contrast to 下値 (したね, lower price).
For this stock, it's safer to buy on dips rather than chase higher prices.
The upside is heavy and it just won't go up.
上値 refers to an anticipated or resistance-level high price in trading, the direct counterpart to 下値's anticipated low price.
upper resistance line; resistance level
Compound of 上 (うわ, upper) and 値 (ね, price). The reading うわね is a standard kun'yomi combination.
