OpenKuber vs LSEG Workspace
LSEG Workspace (formerly Refinitiv Eikon) combines data, Reuters news, analytics such as StarMine, and AI search. Its "attribution" features refer to portfolio performance attribution. OpenKuber builds IROHA, which explains a single NSE stock move by attributing it to market, sector, macro and company-specific causes and testing each. Workspace shows what happened across markets; IROHA explains why an Indian stock moved.
LSEG Workspace describes itself as: "Workspace brings together trusted data, market-moving news, powerful analytics and AI-powered intelligence" (source, checked 2 Nov 2026)
Use LSEG Workspace when…
- You need global data, Reuters news and broker estimates
- You need portfolio performance attribution and analytics
Use OpenKuber when…
- You need the cause of a specific Indian stock move, tested against evidence
- You want causal scenario inputs for Indian equity books

A worked example only IROHA shows
From 21 Aug – 7 Oct 2026 RAYMOND rose +52.8%. IROHA attributes −0.5 points to the market, −1.9 to textile peers and +53.1 to the company, where the dated cause is an aerospace order win and policy news and company news pass every causal test. See the full breakdown.
Using them together
Use Workspace for data, news and portfolio attribution. Use IROHA when you need to explain why a particular Indian holding moved.
Questions
Is IROHA attribution the same as portfolio attribution?
No. Portfolio attribution splits returns by allocation and selection. IROHA splits a single stock move into its causes.
