Hello,
I am reporting inconsistencies found while using the Enterprise Value fields via the Eikon/LSEG Python API (rd library). Below are three issues, each with reproduction steps, code and output. Screenshots and code snippets are attached.
--- ISSUE 1: TR.F.EV does not return quarterly point-in-time data via rd.get_history() ---
In Refinitiv Workspace, TR.F.EV for AAPL.OQ is available quarterly (e.g. MAR-2026, DEC-2025, SEP-2025, JUN-2025, MAR-2025, DEC-2024 all populated) [Screenshot 1].
However, calling:
rd.get_history(
universe=["NVDA.OQ","AAPL.OQ","MSFT.OQ"],
fields=["TR.F.EV"],
start=date(2025,1,1), end=date(2026,5,31),
parameters={"Period":"FQ0"}
)
returns only one value per company per fiscal year, aligned to each company's fiscal year-end date (e.g. NVDA: Jan, AAPL: Sep, MSFT: Jun) [Screenshot 2]. "Period":"FY0" returns an identical result [Screenshot 3], suggesting FQ0 is not being resolved as a distinct fiscal quarter for this field.
Using "Period":"FQ1" advances the anchor by one quarter relative to each company's own fiscal year-end, but does NOT return the most recent available quarter across companies with different fiscal year-ends [Screenshot 4] - e.g. NVDA gets a more recent value, but AAPL/MSFT remain misaligned. This means there is no single Period parameter that retrieves the latest point-in-time TR.F.EV consistently across a universe of companies with different fiscal year-ends, even though this data is clearly available quarterly in Workspace.
Could you confirm whether this is intended behavior and, if so, what is the correct parameterization to retrieve the latest available quarterly TR.F.EV per company via the Python API?
--- ISSUE 2: TR.EV and TR.H.EV (daily series) do not match each other ---
rd.get_history(
universe=["AAPL.OQ"],
fields=["TR.EV","TR.H.EV"],
start=date(2025,12,21), end=date(2026,5,31)
)
returns two Enterprise Value series (Daily Time Series vs Time Series Ratio) that differ by a small, non-constant amount in late Dec 2025-Jan 2026 (e.g. 2025-12-22: 4,049,138,372,410 vs 4,047,908,372,410), then become identical from 2026-02-02 onward [Screenshot 5a and 5b]. Since the discrepancy is not a fixed offset, this looks like a data inconsistency rather than a methodology difference. Could you clarify why these two fields diverge for part of the period and converge later?
--- ISSUE 3: Neither daily field matches the quarterly TR.F.EV ---
For AAPL.OQ, TR.F.EV at fiscal quarter-end DEC-2025 is 4,063,456,910,200. The nearest daily values from TR.EV/TR.H.EV (2025-12-23/24) are approximately 4,069B/4,091B - not an exact match. This may simply be a difference in snapshot timing (quarter-end date vs daily date), but I'd appreciate confirmation on whether these fields are expected to reconcile exactly on matching dates and, if not, what the expected source of difference is.
Please note that the same anomalies also occur when using the Refinitiv Excel add-in, with results consistent with those reported above
Please let me know if you need further detail, additional date ranges or other tickers to investigate.
Thank you
