齊天大聖 x 祥 : how come your cost so low? you bought it a few years back??

JohnW79 : I also want to know, what a low cost price

一步一个脚印 : It should be to sell part of the stock!

招财雄猫 : Accumulated share price

Firstman : Diluted cost means he sold some shares to take profit, to calculate the diluted cost is the current market value devided by the remaining shares. That’s the strategy to keep the cost low and holding the stock for long term. Eventually, the cost will be negative, which means you recover all of your capital and let the profit roll.
