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 Almanac says that the shortest bull market in the past 100 years lasted just 61 days during the summer of 1932 yet still saw the Dow bounce 94%! Those are of course the extremes, but the average bull market of the past century has lasted 755 days and delivered an 85% gain. The current bull run is now four years old and up about 120%, making it significantly above average by both measures.
