- On December 31, 2007 or first trading shortly thereafter, during President Bush's second term
- On March 6, 2009, very early in President Obama's first term, which was the lowest point of the stock market due to the spillover effects resulting from the 2008 financial meltdown, and
- also in February 2014.
The historical stock prices of these companies were obtained from the following two excellent internet resources.... Google Finance and MarketWatch Big Charts.
I made several reclassifications from the way some Companies were grouped into Sectors by Yahoo Finance.
These 2,534 largest US Companies had their equally-company-weighted average stock market prices decline by 54% from December 31, 2007 during President Bush's second Presidential term, to March 6, 2009, very early in President Obama's first term, which was the very lowest point for the overall stock market due to the spillover effects resulting from the disastrous 2008 Financial Meltdown.
But in the slightly less than five years since March 6, 2009, the equally-company-weighted average stock market prices of these same 2,534 largest US Companies have increased by a very impressive 426% through February 2014, led by Companies in the Consumer Goods Sector (up 660%), the Health Care Sector (up 500%), the Services Sector (up 499%) and the Industrial Goods Sector (up 464%).
The lowest performing Sector was Finance, but still its average stock price growth since March 6, 2009 was a very robust 284%.
The Technology Sector's average stock prices were up 375% since March 6, 2009, but this 375% increase was burdened by the much lower stock price appreciation of both its US Telecom Services Subsector (up 88%) and Wireless Communications Subsector (up 89%).
Nearly half of the country believes that the Obama Administration has been bad for US businesses. An average stock price increase of 426% in the past five years clearly says just the opposite.
Also, nearly half of the country feels that US Health Care Companies are being harmed by the Affordable Care Act. Since the average stock market prices of the 297 largest US Health Care Companies have increased by precisely 500% since March 6, 2009, the US stock market is clearly saying otherwise.
Even with this massive 426% average stock market growth, a clear majority of the top management of these 2,534 largest US Companies have very selfishly refused to fairly share their Companies' very robust fruits with the middle and bottom rungs of their organizations, or share with the many unemployed and underemployed by hiring them. This economic selfishness is one of the main causes of massive US income inequality, as is the refusal of the US Congress to properly deal with it.
Below here is a Sector breakdown of the average stock market price changes from December 31, 2007 to March 6, 2009 and from March 6, 2009 to February 2014:
| # of | Average Company Stock Price Increase | Average Company Stock Price Decrease | |
| Sector | Companies | March 6, 2009 to Feb 2014 | December 31, 2007 to March 6, 2009 |
| Consumer Goods | 224 | 660% | -54% |
| Conglomerates | 5 | 515% | -63% |
| Health Care | 297 | 500% | -45% |
| Services | 496 | 499% | -53% |
| Industrial Goods | 233 | 464% | -60% |
| Technology | 415 | 375% | -53% |
| Basic Materials | 282 | 370% | -60% |
| Finance | 582 | 284% | -55% |
| All 8 Sectors | 2,534 | 426% | -54% |
My next step will be to make posts showing average stock price changes for these two periods for each of these Companies headquartered in each US State. From a preliminary review, it should prove to be very interesting.
