Summarize the key takeaways from the 2018 10K’s Net Sales section and the Operating Income (Loss) section, which starts on page 23 and goes to the bottom of page 24. In 250-500 words, briefly summarize what Amazon reported for 2018 and then provide your assessment of the three most important takeaways from the information. Note that the short summary of what Amazon said is essentially factual (according to Amazon), but we want your opinion over what is the most important aspect of what they are reporting. Your analysis can look at what they reported as well as what they do not report, i.e., information that you think would be relevant but which is missing from these sections.
