Apple's Tim Cook is Wall Street hero for a dayMay 21, 2013: 2:29 PM ET
The general consensus among traders on StockTwits was that Cook looked like a capable leader compared with the elected officials doing the questioning.
Cook even managed to plug Apple products.
Once one of the most sought after investments on Wall Street, Apple has struggled with concerns about the company's ability to develop revolutionary new products without its visionary leader, Steve Jobs, who died in 2011.
Cook, who was chief operating officer before taking over as CEO, has been praised for his technical skill. But many investors have questioned his leadership as Apple's stock price has plunged.
After hitting an all time high above $700 last September, Apple's stock has dropped more than 30%.
The stock has regained some ground in recent weeks as bargain hunters still see Apple as a good long-term bet. Apple also announced plans to return $100 billion to investors over the next few years by repurchasing stock and paying dividends.
While Cook came out looking like a winner, Congress definitely didn't gain any new fans on Wall Street. Of course, traders are typically not big fans of the legislative branch.
