Wednesday, July 21 is another busy day on Wall Street. TheStreet outlines the key earnings reports and some economic data to watch. On the earnings front, the notable companies releasing their latest quarterly earnings include soda maker The Coca-Cola Co. (KO), The Boeing Co, (BA), cloud computing provider EMC Corp (EMC), chipmaker Qualcomm Inc (QCOM), American Express Co (AXP), and casino operator Las Vegas Sands Corp (LVS). Aerospace company Boeing is scheduled to release its earnings report for the 2015 second quarter before the market opens. Analysts are anticipating a year-over-year increase in revenue, but a year-over-year decrease in earnings per share for the quarter ended June 2015. Wall Street estimates call for a profit of $1.42  a share on sales of $24.22 billion, according to analysts polled by Thomson Reuters. In the same quarter of last year, the company reported earnings of $2.24 per diluted share on revenue of $22.05 billion in the second quarter. TheStreet's Jim Cramer, Portfolio Manager of the Action Alerts PLUS Charitable Trust Portfolio says investors should focus more on the aerospace giant's long term outlook, and less on the short term. Instead of just trading the stock, Cramer suggests that investors wait until the part of the Boeing earnings call where they issue guidance. Chicago, Ill.-based Boeing is an aerospace company that develops, produces and markets commercial jet aircraft, as well as engages in the research, development, production and modification of manned and unmanned military weapons.
