This is an addendum to my previous post.
Assuming starting with 1,000 shares at $10.
1st sale: $13, sell 1/7th of 1,000 = 142 shares x $13 = $1,846. Leaving 858 shares x $13 = $11,154.
2nd sale: $16, sell 1/7th of 858 = 122 shares x $16 = $1,952. Leaving 736 shares x $16 = $11,776.
3rd sale: $19, sell 1/7th of 736 shares =105 shares x $19 = $1995. Leaving 631 x $19 = $11, 989.
4th sale: $22, sell 1/7th of 631 = 90 shares x $22 = $1,980. Leaving 541 x $22 = $11,902 (first dip).
5th sale: $28, sell 1/7th of 541 = 77 shares x $28 = $2,156, leaving 464 x $28 = $12,992.
6th sale $34, sell 1/7th of 464 = 66 x $34 = $2,244. Leaving 398 x $34 = $13,532.
I think you can see that the selling of 1/7th of positions, works far better at increasing the remaining value of the holding, as well as providing for increasing value of each partial sale.
