Market slowed.... 

Now got time, plenty of time. Sorry to keep you waiting.

Buy share at 1.00
Share price now 1.50 and you sell at 1.50.
Dividends received for x years is 40 sen.

What's the gain?

Gain = Sell price + dividends - buy price = 1.50 + 40 - 1.00 = 90 sen.

Percentage gain = Gain / buy price = 90 sen / 1.00 = 90%.

Using EGO boosting method by deducting dividends from cost of share.

Gain = Sell price - cost of share.
Cost of share = 1.00 - 40 sen = 60 sen.
Gain = 1.50 - 60 sen = 90 sen.

Percentage gain = Gain / cost of share = 90 sen / 60 sen = 150%.
One method shows 90% gain.
One method shows 150% gain.



No right no wrong? 

Other scenario.

Cost of shares = 1.00.
Company gives 10 sen shares each year.

Using deducting dividends method.
After 10 years, cost of shares = 1.00 - (10 years x 10 sen) = 1.00 - 1.00 = 0.

Question? How to count percentage gain on year 10? 
Can we divide by zero?

Next question. Year 11. ( Long term investing hor)
Total dividends now = 1.10.
Cost of shares = 1.00
How to account this new cost at year 11?
Cost of shares become negative? 
Too long jor ....
