So your objective here is to earn more profit?

If counter A was bought in 2018 at 100 USD (100 units), then bought again at 2022 at 200USD (100 units), and now in 2024 you sell 100 units for 250USD, why do you care 'which' units were sold? You are still holding 100 units (post sale) which have unrealised value of 250USD.

if someone values "cosmetics" (even if there's no practical function), who are we to judge

can you give a hypothetical example? start with sample entry prices/cash balance, and the hypothetical scenario A or B?

it's ok if you don't plan to plot it out (due to time constraints). we're just here to make money so i'm more than happy to leave it aside

ok. so assuming market reopens on Tues @ same price of $140.52, instead of selling xxxx5 shares, you'll just need to sell xxxx1.1816 shares.

if FIFO, you'll liquidate all of 1st purchase, and some of 2nd purchase
if LIFO, you'll liquidate most of 4th purchase

both will result in same amt of freed up capital

(redacting the beginning figures of shares in case of privacy)

your motivation to sell the Dec 2023 tranche is purely to avoid seeing red... for that tranche

your balance remains the same regardless of selling the first few tranches or the last few tranches...

If you know there's going to be a correction, then your 'letting winners run' is actually costing you money. Because if you sold right now, then there's a correction, you have both locked in your gains AND will be able to repurchase at a lower price.

I still don't understand after like 2 pages reading. Just making sure I'm on the same page... There's literally no difference in terms of the final outcome, do you agree?

Technically speaking, I GUESS it would have different unrealised profit vs realised profit on paper... But that's kinda meaningless, because if you REALLY want to pocket everything and close shop, they'll all still turn into realised profits, so I don't understand your insistence...

Okay, in my opinion definitely you're prioritizing a certain kind of optics over reality here.

Let's say, 2018 you bought ABC with price 100 USD.

2022 you bought ABC with price 230 USD.

Now (2024) the price is 250 USD. You anticipate a correction. Imagine you have perfect ability to tell the future, you know that price will drop to 215 USD later this year.

Your intention is to sell all your 2022 units to 'reset' that tranche, gain a bit of profit, and once correction you can re-enter. But your 2018 units you want to hold so that you can 'let winners run'.

(If anything wrong with above simple example please make corrections).

What I (and some others) are saying is that none of the above matters except for annual tax reporting. And what I'm saying in addition is that if you sell ALL your units now (at 250 USD) you have already made 150% on your 2018 units. Re-entering at a higher entry price would not lose you any money. You are LOCKING IN your gains (this can actually be a smart play, depending on the portfolio/horizon), which is objectively a good thing and doesn't affect your fund value at all.

Secondary example, if stock ABS would one day drop to 110 USD price, would you still hold on to it because you bought it cheaper in 2018? If you had sold and bought after correction at a higher entry price would that have convinced you to sell it earlier? In both those cases then you're probably engaging in a form of sunk cost fallacy.
