The bell became the preferred way to signal Wall Street's opening after using a truck's air horn resulted in traders passing in front of the podium, pumping their arms up and down in an effort to get the horn blown again. Fine-tune your financial signals with today’s Groupon: for $29, you get five online stock-trading courses from Lex van Dam Trading Academy (a $630 value).
A professional hedge-fund manager and one-time trader with Goldman Sachs, Lex van Dam opened a trading academy to teach Main Street folks of all skill levels to turn a profit in the stock market. The online academy organizes material into five 40-minute modules based on the basic principles of successful trading, including chart analysis and risk management. Aspiring marketeers learn to make savvy trades based on a deep understanding of the market, rather than from newspaper predictions or company horoscopes. Company-evaluation modules reveal which financial numbers matter and which are irrelevant, and trading psychology teaches students to make smart trades without letting emotions sway them. Groupon holders can watch each module up to five times, ultimately gaining enough insight to potentially design strong personal portfolios. Lex van Dam taught several novices to out-trade pros on BBC's Million Dollar Traders, a reality show that turned ordinary people into profitable market wizards and insufferably smug Monopoly players.
