Apple posted its first sales drop since 2019, but analysts say the tech titan's stock is still set to climb nearly 30% over the next year

• Apple's latest earnings and revenue fell short of expectations, but that shouldn't discourage investors.
• But Wedbush and Jefferies said investors should still see the tech heavyweight's stock as a buy. 
• Any weakness in the stock is a "more appealing buying opportunity," said Jefferies. 

Apple missed estimates for its fiscal first-quarter earnings and sales, but two analysts said the tech heavyweight should still be on investors' buy list.
