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.
The current bull market isn't even the the runner-up in performance: The baby-boom bull market in the 1950s is the second-best performer, with the market having risen 267% during its seven years. Nor is the ongoing bull market the one in which stocks became most expensive, though it's getting close.
