If it were that easy, there would be no workers left in any field, trade or profession.
well not asking you to trade everyday. Of course research and analysis does come to play as there's no free lunch to making money.
say somethnig bads happens in europe - how would it affect the markets here? doesn't take a genius to work it out. you can trade on gold prices, coffee prices and other commodities too.
it's just like buying property - u can use the lazyman's method and buy and hold and wait like majority of investors do or you can buy property and manufacturer growth by renovation.
many people just don't bother - and trade standard shares etc that's the difference btw making the extra step to making more gains with some level of risk rather than speculating on what if scenarios.
