It is a tale of contrasting fortunes for two of tech's biggest names.
Apple's share price has risen seven percent today, while Twitter has slumped 13 percent.
Apple latest results were better than expected, with sales of just over 40 billion iPhones in three months.
Twitter has slumped as user numbers have only grown 3 percent to 313 million monthly users.
Neither user numbers nor revenue are anywhere near what investors had been hoping for.
