My general plan is to build a portfolio of 'free carried' securities in my super portfolio which I will hold till retirement.

The approximate process is to sell 20% of current holdings when the price rises by 25%. If I do that 4 times, I am free carried.
Final holding = initial * (0.8*0.8*0.8*0.8) = 41% of initial
Return = initial investment * (0.2*1.25 + 0.2*1.25*(0.8*1.25) + 0.2*1.25*(0.8*1.25)² + 0.2*1.25*(0.8*1.25)³ ) = 100% of initial investment.
Price at last sale = (1.25)⁴ times purchase price = 2.44 times, so I need to look at potential 3 baggers for this to work.

Dividends, tax and brokerage mean there are a few adjustments required.

I put my sell order @7.25 this morning, that will be my 3rd sale, one more to go at ~$9.

My current average price is around $3.80.
