Johnson & Johnson (NYSE: JNJ ) announces earnings on Tuesday before market open. The New Brunswick, New Jersey-based healthcare company has become one of the strongest, longest-running brands in existence. However, challenges with drug patent expirations have blunted earnings growth in JNJ stock. This has left JNJ trading in a range for more than two years. Though this report will probably not deliver any meaningful surprises, investors still need signs that earnings growth will resume in Johnson & Johnson stock to break the equity out of its range.
