NEW YORK ( TheStreet) -- In the wake of reporting quarterly results new data received by ValuEngine can result in upgrades or downgrades to the stocks I profiled pre-earnings. A stock can also have a ratings change if the directional volatility outruns its price target to the upside and triggers a downgrade, or falls far enough below its price target to merit an upgrade.Amazon.com (AMZN) ($254.81 vs. $274.70 Friday) has been upgraded to hold from strong sell following its $19.89 price plunge Friday. The stock is still overvalued by 6.0% and is projected to slide another 4.3%, but since this is within a plus/minus 5.0% projection range the upgrade to hold occurred. My semiannual and annual value levels are $241.23 and $226.80 with a weekly pivot at $258.38 and quarterly risky level at $278.28.
Today I profile seven stocks that report quarterly results with the theme of getting a fresh read on big Pharma, healthcare providers and spending via credit cards.
