While there is no evidence as to what caused the decline, there was a report published on MarketWatch Tuesday morning that quoted an David Trainer, president of New Constructs, a Nashville-based research firm, as saying that Apple shares are worth $240.

Apple is expected to release a line of new products, including its next generation iPhone and iPad, this Fall. However, the company is widely believed to also be unveiling a product in an entirely new category at the end of the year which many speculate is a smart TV.
