Apple's preannouncement this week has set a New York law firm into high gear smelling blood in the water. We're learning that Bronstein, Gewirtz & Grossman, LLC is investigating potential claims on behalf of purchasers Apple Inc. ("Apple" or the "Company") (NASDAQ: AAPL). The investigation concerns whether Apple and certain of its officers and/or directors have violated federal securities laws.

On January 2, 2019, Apple revealed that its revenue for the first fiscal quarter of 2019 would be more than 7% lower than it expected because of "lower than anticipated iPhone revenue, primarily in Greater China, [which] accounts for all of [Apple's] revenue shortfall to [its] guidance and for much more than [its] entire year-over-year revenue decline."

Conversely, on November 1, 2018 CEO Tim Cook stated during Apple's fourth quarter 2018 conference call, that "[o]ur business in China was very strong last quarter. We grew 16%, which we're very happy with. iPhone in particular was very strong, very strong double-digit growth there." Following this news, Apple stock dropped $11.97 per share, or roughly 7.5%, during aftermarket trading hours on January 2, 2019.

The lawsuit's bottom line: "As a result of Defendants' wrongful acts and omissions, and precipitous decline in the market value of Apple's securities, Plaintiff and other Class members have suffered significant losses and damages."
