Tis a very important note for as an amature tax-advantageous practice! You can buy something similar, though. eg trade AMD for Intel or some such. Where investors are concerned about markets rather than invidivuals stocks (AMD and INTC are both hardware tech stocks), the notion is that a rising tide lifts all boats, and that large, sector-related good news for Intel is good news for AMD. It's not strictly true, obviously, but it's close enough that the practice is worthwhile.
