IROHA for registered investment advisers

When a client asks why their portfolio fell, an RIA needs an answer that is fast, sourced and defensible. IROHA explains each holding’s move by market, sector and company-specific cause, with evidence, so advisers can document the reasoning behind their advice and stress-test portfolios before the next shock.

Explain a drawdown to a client in minutes

For every holding that moved sharply, IROHA shows how much came from the market, how much from the sector and how much from the company, with the filing or news item behind the company-specific part. That is the explanation a client actually asked for, in a form you can forward.

Keep a record of the reasoning behind advice

Each explanation is dated and cites its sources, so it can sit in the client file next to the advice it supported. When a regulator or a client asks why you held or changed a position, the record already exists.

Stress-test model portfolios

Set a market fall, a sector shock or an event and IROHA returns a range for each holding. Run it on your model portfolios before a policy announcement or results season rather than after.

What the output looks like

Take RAYMOND, which rose +52.8% from 21 Aug – 7 Oct 2026. IROHA puts −0.5 points on the market and −1.9 on textile peers, names the dated cause, and shows which drivers pass every causal test: policy news and company news. Across all 52 big RAYMOND moves since 2015, the model leaned the right way before 41. The full study.
