Have a small investment in Keppel Corp bought at $8. Plus when O &G sector was hit. 

Lesson 1 - It is better to buy when the prices is rising . Not when it is falling . You don't know where is the bottom. Emotional reasons for buying then. It was a blue chip. Can have bragging rights and to attend Agm to monitor the shares. Thought  it was cheap then when compared to the historical price. Have a yield of around 2.5 %

Lesson 2 - Reasons for selling on News of Keppel Corp being hit with a Usd fine of 423 millions For corruption and bribery. Thought it will definitely open lower by at least 0.31 cents per share as reported in businesstimes. Perceived negative sentiments in the market. Thinking of selling and buying back later at a lower price. Sold at starting bell @$7.14

Another reason at the back of my mind is to switch the capital to a higher yielding stocks then Keppel Corp instead. Definitely dividend will be hit in future.
