Supply and Demand in the stock market are influenced by various factors. One of it is the direction the company is going, the action its taking. Usually the stock price changes even before the news about a change in the company are made official. This is what makes it hard to track when to enter the stock or exit it.
On example for the above is the NVDIA Corporation.
On 5th January 2011 the Wall Street Journal brought the news that the Nvidia Group is is becoming a direct competitor to Intel Corp. and Advanced Micro Devices (AMD) by developing their first computer processor. This processor combines Nvdia's graphics and computer processing on one chip, leading the company in a new direction. Chief Executive Jen-Hsun Huang said: "This is one of the most strategic and important announcements ever made at Nvidia."
After this announcement the stock price climbed up about 40%!!!
VantageTrade was able to detect the the right time to enter before those news even came out.
A BUY signal was issued on 22nd December 2010 at a price of $15.03. The first target was reached even before the Wall Street Journal wrote about this development. The rising of the stock continued for another 2 weeks until VantageTrade suggested the investor to SELL the stock at a price of $22.41.
This gave a profit of 49%!!!
