http://www.blockdesk.com./bd101_concept.htm -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- BLOCKDESK CONCEPT -------------------------------------------------------------------------------- The best informed investors are those with the most to lose, and those most frequently at risk. Otherwise they don't survive. When institutions like mutual funds and pension funds make investments they buy stocks in big amounts, called blocks. The brokers handling these trades are block traders, and are usually the most experienced and skillful people in their firm. Why? The average block trade is 25,000 shares of a $40 stock, or a $1 million ticket. Upwards of 35,000 of these trade each day. If the broker wants to do the trade, he has to do it quickly, and near the price the institution wants. In 90% of these trades the broker has to buy or short some part of the block that cannot be placed with other investors. He has a lot to lose, frequently. With so much riding on their bets block traders see to it that they stay well informed, gathering information from every possible source to be immediately at hand in support of their trading decisions. The future is a risky place, so they don't take any unnecessary chances. Along with being superbly informed, they protect themselves with insurance covering their upside and downside risks. They won't buy more insurance than they need, because its cost comes out of their trading profits. We know how to translate what they are willing to pay for the insurance into their forecasts of how far the stock's price might run, both up and down. By looking at their price range forecasts you have both upside and downside prospects for price change. Measures which can be compared directly between stocks, regardless of the company's type of business. Our 20+ years experience shows that it is more profitable to bet with these pros, not against them. They do know when stocks get cheap, and where there may be trouble. No matter how you come to your stock value conclusions, we believe you should know what these well-informed, active professionals think. Buying and selling at better prices can add significantly to your returns. OVERVIEW HISTORICAL PERFORMANCE
