Investors brace for more stock volatility on Apple earnings

 For years, Apple Inc was a stock investor’s dream regardless of the market environment. But now concern about the iPhone maker’s growth has made many investors wary about a big share swing after its earnings are released on Tuesday.

Options pricing on Friday suggested a post-earnings move of about 7.5 percent by April 26. That is far more than in the past and reflects the fact that Apple stock has become more volatile.
