The reality is that in the modern world - especially with the power of the internet - there is very little information that is not in the public domain somewhere. However, the world now has information overload. Whilst the information might be available, few people now have the time to find or understand it. The people who know these things and can 'join the dots' have regular opportunities for stock market investment.
D (Weak) - The stock has underperformed the universe of other funds given the level of risk in its underlying investments, resulting in a weak risk-adjusted performance. Thus, its investment strategy and/or management has not been attuned to capitalize on the recent economic environment. While the risk-adjusted performance of any stock is subject to change, we believe that this fund has proven to be a bad investment over the recent past.
E (Very Weak) - The stock has significantly underperformed most other funds given the level of risk in its underlying investments, resulting in a very weak risk-adjusted performance. Thus, its investment strategy and/or management has done just the opposite of what was needed to maximize returns in the recent economic environment. While the risk-adjusted performance of any stock is subject to change, we believe this fund has proven to be a very bad investment in the recent past.

Firms such as Trade King, eTrade, Charles Schwab and Ameritrade provide a range of online tools. These will give you a feel for how portfolio management software works without having to pay extra to learn. However, these services typically offer no advice (known as execution only), which means that a separate service will be required for information analysis.
Businesses you don't understand -- Here's a great rule of thumb that works for beginners and expert investors alike. If you can't clearly explain what a company does and how it makes money in a sentence or two, don't invest in it.

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. Here’s where that rational voice from calmer times — your investing journal — can serve as a guide to sticking it out during the inevitable ups and downs that come with investing in stocks.
