I have a query on share disposals and the same day/30 days rules which I thought I always knew the answer to but some software has made me doubt myself.
31/12/2021 Pool 700 shares
13/1/2021 Sells 700 shares and the same day buys 500 shares
14/1/2021 Buys 650 shares and sells 600
Same day is always first. So 13/1/2021 the sale of 700 is matched with the 500. 200 unmatched. So we have to look at the next 30 days before the pool.
On 14/1/2021 there is a further purchase and sale. Is the 200 unmatched above matched with the 650 purchase as we are still dealing with the 13/1 sale, thus the 14/1/21 600 share sale is matched as 450 same day and 150 pool.
OR does the 600 sale on the 14/1 mean that there is only 50 that can be matched to the 200 from 13/1 (as the 600 is matched to the 650). The 150 unmatched on 13/1/21 will then come from the pool?
Overall the same position applies in that 150 are taken from teh pool somewhere, but I am interested in the correct way of doing this?
My opinion is 'same day' always applies first, so the 14/1 600 dispsoal is matched with the 650 purchase leaving only 50 that can be matched with the 13/1/21 disposal.
Interested in views as I have used a website calcualtor and a piece of software. One does one way and the website the other!
