Stock market conspiracy theorists, prepare to have your thought balloons burst.
For as long as I've been writing for the Fool (and even more frequently since I began covering the ratings of Wall Street's analysts), I've heard a theory voiced over and over: The stock market is rigged. Big-name investment bankers like Citigroup
In its simplest form, the theory goes like this: Say Citi comes out with an upgrade to "buy" on the stock of Superior Urban Consolidated Kinetic Rollerskates (Ticker: SUCKR). The reason Citi upgraded isn't that it thinks SUCKR is really a buy, but because Citi's playing you for a fool (small "f"). Citi wants you to buy the stock -- which it secretly owns -- so Citi can unload it for a fat profit. Conversely, if B of A tells you to sell Gondwanaland Industrial Metals and Mining Empire (Ticker: GIMME), this isn't because Bank of America hates GIMME, but because it loves the stock and hopes to scare you into selling on the cheap.
Up is down, and down is accordingly up
According to the conspiracy theorists, what you should really do is sell when Wall Street says "buy," and buy when it says "sell." Savvy? There's just one problem with this theory: Far from publicizing their market-moving news, across Wall Street, bankers are pulling down the shades, dimming the lights, and going dark.
Earlier this week, we learned that Barclays
The banks are now considering whether to appeal. Whatever they decide, at least one mystery has been resolved: There's a reason so many of the biggest banks, which up until about a year ago routinely provided ratings for independent review, have suddenly gone dark and stopped publicizing their stock ratings.
It's not because they want to influence which stocks you buy and sell. In fact, it's the opposite.
