Following regular trading Tuesday, we saw earnings reports posted from some of the biggest bellwethers in their respective industries: Apple (AAPL), Twitter (TWTR), Chipotle (CMG) and Buffalo Wild Wings (BWLD). We also saw some of these same stocks take big hits from after-market traders who were apparently less than pleased with results. Apple missed on earnings for its first quarter in at least a year. The company's fiscal Q2 2016 results were a dime light on the bottom line and nearly $1 billion short on the top-line. Weaker iPhone sales and lower comps in China were cited as the main reasons: Apple Misses Q2 Earnings, Revs on Weaker iPhone Sales Social media staple Twitter managed to top earnings expectations in its Q1 report after the closing bell, though revenues came in noticeably worse than expected. Even further, guidance was way down for Twitter's Q2, and traders have taken TWTR shares down as well: Twitter Tanks on Revenue Miss, Weak Guidance Chipotle Mexican Grill also topped earnings expectations while missing on sales for its Q1 results. The fast-casual restaurant chain was no stranger to difficulties over the last quarter, and late trading has taken CMG shares down as well -- just not as low as AAPL or TWTR: Chipotle Tops Q1 Earnings Estimates, Revenues Down 23.4% Y/Y Finally today, Buffalo Wild Wings (BWLD) plummeted after-hours based on its Q1 earnings and sales misses, even though both reflected double-digit growth from the year-ago quarter. BWLD shares are down double-digits in the after-market, as well: Buffalo Wild Wings Stock Plunges on Q1 Earnings Miss Want the latest recommendations from Zacks Investment Research?
