Part of the biggest issue I have with trading, and investing, for that matter, is feeling comfortable that the sources of information I am relying upon to pull the trigger with my personal money (not 'opm') are inherently reliable. We've all heard the myths and stories, read about the very real scandals, and have seen the tangible results when the 'distributors' and disseminators of misinformation, be they high ranking corporate officers, employees of brokerage firms or hedge funds, and even media 'professionals' themselves, have materially misrepresented information that was relied upon by both investors and traders, much to their financial demise, while those intentionally spreading such misinformation profited handsomely. So, who or what do you rely upon, aside from your own perceptions and interpretation of such information or data, that you have inherently trustworthy, when trading or investing? Also, what sources of information do you believe should never or rarely be relied upon? I'll volunteer a first offering: Despite a nearly dogmatic adherence to what I believe are somewhat outdated and naive principles of macroeconomics and modern trade (the commerce type of 'trade,' not the trading kind of 'trade'), The Economist magazine is an indispensable and more often than not reliable source of information in helping me establish investing strategies.
