Apple cannot rely on huge shares buyback alone as focus falls on earnings         

Apple is expected to announced a share buyback programme of as much as €90bn.

A massive share buyback may not be enough for Apple investors amid the worst month for big tech since the global financial crisis. 

Seen as a safe haven within the tech and social media, Apple is expected to announce a share buyback programme of as much as $90bn (€84bn) when it unveils its quarterly results after the markets close on Thursday evening.
