Why a Buy and Hold and don't even bother thinking of Selling Can be Wrong Strategy for You? - Part 2

http://createwealth8888.blogspot.com/2009/07/why-buy-and-hold-and-dont-even-bother.html <-- If you may wish to read Part 1 If your strategy of "buy and hold" over very long term e.g 10-30 years is for the primary reason to receive dividend income and for future capital appreciation if any.

The truth is that few companies are immune to economic and market cycles, and from time to time, they may need to raise more capital to meet their corporate needs. Companies may raise additional capital through enlarge private share placement, convertible bonds or warrants, or right issues, and etc. Such corporate actions can inevitably expose you to future share and dividend yield dilution risks and may even have some valuation impact on your initial share purchase price.

Do consider this risk. Cheers!
