Before Seagate's (STX) earnings after Tuesday's close, Nitin Sacheti tells investors to keep "high expectations" in mind for the company and its peers. He points to companies not meeting investor hopes as a "hiccup" to the trade even if earnings continue to come in strong. Nitin later explains how Seagate, Micron (MU), SanDisk (SNDK) and Western Digital (WDC) all play their role in the memory chip industry. Tom White turns to the options front for Seagate.
