Lumens measure how much light you are getting from a bulb. More lumens means it's a brighter light; fewer lumens means it's a dimmer light. Lumens are to light what. Pounds are to bananas. Gallons are to milk.
The Kuala Lumpur Composite Index is the world's longest running bull market. Since January 2008 the KLCI has not had a 20% correction (which represents a bear market and the end of a bull market). Malaysian shares have moved up 88% during this bull run. But it hasn't been easy.
A bull market is a market with high esteem and high optimism. With a positive outlook for the future, the bull market most often refers but non exclusively to the market pushing equity prices, but also other financial instruments such as bonds, currencies and asset backed securities. Hence gains the name bull for the aggressive nature of the market.
