From what I gather generally the various tip services consistent of a combination or variation of the following:
- Educated Information from industry veterans
- Computer/Data Analysis and Indicators of opportunities/risks in the stock market
- Specialized Industry/Business Analysts who look for and predict likely opportunities
If I'm missing something of course please correct me. They all of course promise they're the best and show charts saying their returns have been higher than competitor/index ABZ for XYZ years.
So which services do you know about and which ones have you used? Have you actually been able to make good use of the services to buy low and sell high, and more importantly to sell before a stock crashes?
I'm curious to know what (if) any services predicted the 2008 stock crash successfully.
