- The market's psychology is strong. Going against a trend is usually a bad and costly idea. That is one reason why the stock market is likely to go up for a while - when many people follow a pattern, a movement is created, that becomes self-fulfilling. We agree with the majority that it looks much better. Key figures will improve and companies will beat analysts' expectations, which will support the stock market during at least the first half of 2010, writes Agenta in a comment.
