30 Largest US Scientific & Technical Instrument Company Stock Prices Down 56% Due to Financial Meltdown Spillover Effects, Then Up 393% Under Obama and the US Fed

I found 30 US Scientific & Technical Instrument Companies classified in the Technology Sector at Yahoo's superb Finance website with current Total Market Capitalizations of at least $100 mil each and which also had their common stocks trading on each of the following three dates :

• On December 31, 2007 during President Bush's second term
• On March 6, 2009, very early in President Obama's first term, which was their lowest point due to the spillover effects resulting from the 2008 financial meltdown, and 
• also on the most recent date February 11, 2014.

The historical common stock prices of these companies were obtained from the following two excellent internet resources....  Google Finance and MarketWatch Big Charts.

These 30 largest US Scientific & Technical Instrument Companies had their average stock prices decline by a huge 56% 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 average stock prices of these same 30 largest US Scientific & Technical Instrument Companies have increased by a very robust 393% through February 11, 2014, led by Hampton, VA-based Measurement Specialties's massive 2,009% stock market price increase and by Houston, TX-based Geospace Technologies's 1,407% stock price increase.

Clearly, the investors in and employees of a clear majority of these 30 largest US Scientific & Technical Instrument Companies must be pleased with the impact of actions taken by both the Obama Administration and the US Fed to successfully rescue the US economy from its extremely weakened state.

Below here are the stock market prices of each of these 30 largest US Scientific & Technical Instrument Companies on February 11, 2014, on March 6, 2009, and on  December 31, 2007:
