Investors have been hearing an awful lot that Apple (NASDAQ:AAPL) might cut iPhone 5c orders from its suppliers.

NPD DisplaySearch is the latest to chime in, saying iPhone 5c orders appear to have been reduced by 35%. On the other hand, DisplaySearch offers up some very good news that Apple has increased iPhone 5s orders by 75%. That's potentially a large jump in Apple's most important product, and a sign that demand is good for the high-end device that carries higher margins.

As with all supply-chain rumors, investors should consider this information with a healthy amount of skepticism. Rumors of this nature only provide a possible aspect of the broader picture and shouldn't dictate the overall investment decision. For more reliable information on Apple's supply chain, investors should check official SEC filings.
