The stock exchanges also maintain all company news, announcements, and financial reporting, which can be usually accessed on their official websites. A stock exchange also supports various other corporate-level, transaction-related activities. For instance, profitable companies may reward investors by paying dividends which usually comes from a part of the company’s earnings. The exchange maintains all such information and may support its processing to a certain extent. (For related reading, see "How Does the Stock Market Work?")

In the professional world, one of the key concepts is diversification. Harry Markowitz is a Nobel prize winning economist and one of his major discoveries was that adding new asset classes can dramatically alter the overall risk profile of a portfolio. His finding was that a portfolio that contained very low risk assets would normally benefit from lower volatility and higher returns if a higher risk asset was added. This is due to the likely lack of correlation between high and low risk asset classes.
Alternatively, you may be looking at digging hidden gems that may be well below the top 50 or top 100 projects, but still have a very solid technology or are undervalued. Doing your own research may help here, but of course it will require more investment and time spent, with a possibly longer ROI (Return on Investment) but the hope of higher gains.
Rarely is short-term noise (blaring headlines, temporary price fluctuations) relevant to how a well-chosen company performs over the long term. It’s how investors react to the noise that really matters.
