My first trading rule. 我的第一投資原則

My first trading rule is, always remember that market price is determined by the law of demand & supply which has reflected the result for both psychology of buyer and seller. The market price tend to be affected by external factors like economic factors, political issues, rumours, newpapers, company fundamentals... which indirectly make a impact on people decision for buying stocks in which often driven by some emotions like greedy, fearful, complacent, expectation.

我的第一投資法則是永遠記住市場的價格是由供需決定的，反應買賣雙方的心理結果。往往市場價格的變動是由外在因素影響像經濟層面，政治驅動，流言，報紙, 公司基本面，間接來左右人們的內在情緒而導致像貪婪，恐懼，期望，自負的情緒，來做出買賣決策。
