I know this has been discussed a few times, but the docs are still incorrect
and I’m unable to find a complete example. I’m using beancount v2 because
Fava’s not been updated for v3, yet.
NVDA recently split 10:1. I previously purchased 2 shares:
option "operating_currency" "USD"
2024-02-14 open Equity:Opening-Balances
USD
2024-02-14 open Assets:Cash
USD
2024-02-14 pad Assets:Cash Equity:Opening-Balances
2024-02-14 open Assets:Stocks:NVDA
NVDA
2024-02-14 commodity NVDA
2024-02-14 * "Buying some NVDA" ""
Assets:Stocks:NVDA 2.00
NVDA {733.09 USD}
Assets:Cash
2024-05-31 balance Assets:Stocks:NVDA 2
NVDA
2024-05-31 balance Assets:Cash 0.00
USD
The pre-split stock price (per Yahoo and bean-price) was 1,096.33, and my
Fidelity account confirms that I have 20 shares. Per the docs[1], I would do
(I think):
2024-06-02 * "NVDA 10:1 stock split" ""
Assets:Stocks:NVDA -2
NVDA {1,096.33 USD}
Assets:Stocks:NVDA 50
NVDA {109.633 USD}
bean-check fails, however:
nvidia_split.beancount:24: No position matches
"Posting(account='Assets:Stocks:NVDA', units=-2 NVDA,
cost=CostSpec(number_per=Decimal('1096.33'), number_total=None, currency='USD',
date=None, label=None, merge=False), price=None, flag=None, meta={'filename':
'nvidia_split.beancount', 'lineno': 29})" against balance (2.00 NVDA {733.09
USD, 2024-02-14})
Explicitly using the lot in that transaction fails, too:
2024-06-02 * "NVDA 10:1 stock split" ""
Assets:Stocks:NVDA -2 NVDA {733.09 USD, 2024-02-14} @ 1096.33 USD
Assets:Stocks:NVDA 20 NVDA {109.633 USD}
The error is:
nvidia_split.beancount:24: Transaction does not balance: (726.4800 USD)
2024-06-02 * "NVDA 10:1 stock split" ""
Assets:Stocks:NVDA -2.00 NVDA {733.09 USD, 2024-02-14} @ 1096.33 USD
Assets:Stocks:NVDA 20 NVDA {109.633 USD, 2024-06-02}
So it seems the price of 1096.33 is being ignored and I’m trying to purchase 20
shares at 109.633 USD using 2*733.09 USD and the “gain” of 363.24 USD per share
is being lost.
What is the proper way to reflect a stock split?
Thanks,
Brian
