Youdao ( $DAO) Shares Decline -12% Over 30 Days Following Earnings and Insider Sales (See the latest news for any ticker on Tickeron.) Youdao (DAO) shares fell roughly 12% over the last 30 days, from about $16.79 to around $14.70, as investors took profits after a sharp multi-month rally. The decline followed a strong second-quarter earnings beat that was offset by a revenue miss, softer smart-device demand, and rising memory-component costs. Rule 144 insider-selling filings from executives, including President Jin Lei, amplified concerns about profit-taking near multi-year valuation levels. $ARLO $COE $ADT $KODK $CASS
