The three charts you are looking at on this page are all of the same company, Qualcom. I could go into specific details about this company and their business operations and why they are a good company. I could also go into a discussion about why another company in the same sector might be a better investment. In short fundamental analysis only gives you a part of the picture behind a stock chart.
In truth fundamental analysis or the analysis of a business and the industry they are in is important if you plan on being a long term investor in a company or industry. In the short run of days, weeks, or even months that plays a relatively minor factor in whether the stock is being bought or sold in a quantifiable fashion.
Positions in companies are constantly being bought and sold by different institutions and individuals depending on what their expectations of the stock or industry are.
A mutual fund might be purchasing a stock because they see it as undervalued over the next 12 -18 months and they want to take a position in it. An individual investor or a speculator may not wish to hold on to a security that long so their window of opportunity may seem different to them.
So timing is important to both the institution and the individual but seen from different perspectives makes the play a little more colorful.
