About

Iron Hall is a private investment office, built on independent research and the conviction to act on it.

The office invests its own capital in public markets. It uses derivatives, futures and options, to express its views and to define their risk in advance, and it holds concentrated positions in businesses priced below what they are worth. The research and the systems behind it are built in house, and every position is sized by conviction rather than by mandate. For now, the office invests only its own capital.

The Difference

The advantage is not scale. It is the discipline to stay small.

Markets are neither perfectly efficient nor freely exploitable. They are efficiently inefficient: priced well enough that the obvious edges are competed away, yet loose enough that small, persistent dislocations remain for whoever can reach them. Those openings are real but shallow, and they close quickly. They reward the capital nimble enough to act before the window shuts, and most institutional capital, committed at a size that moves the very prices it depends on, is not.

~80%
of family offices outsource their investment management. Most hand the capital they run to large external funds, giving up the edge that only comes from managing it themselves.
100%
of the capital here is managed in-house, on our own research, models, machine learning and algorithms. Nothing is handed to a third party.
01Capacity

A ceiling set before the capital

The dislocations that surface day to day are real, but small, and they close quickly. The edge in exploiting them erodes as assets grow, so the size is fixed before the capital is. The largest managers are limited not by talent but by scale.

V(S) = S(α₀ − λS)Value added peaks, then falls away with size.
02Market impact

Size is a cost when you trade

A book measured in tens of billions cannot enter or leave a position without moving the price against itself. A smaller book takes a position and leaves it within a session, with less slippage and less signalling.

slippage ≈ σ √(Q / V)The cost of trading rises with the size of the order.
03Convexity

Asymmetry defined in advance

The book is traded directly, in equities and in options, where convexity lets a deliberately small base define its risk in advance rather than rely on size to carry a view. Risk is shaped before a position is taken, not adjusted after it moves.

P&L ≈ ½ Γ (ΔS)²Asymmetry is shaped before the position is taken.
Approach
01 / 03

Derivatives

Futures and options used with intent rather than leverage. Volatility, convexity and dealer positioning shape structures that express a view or protect one, with the maximum loss defined before the position is opened.

02 / 03

Value Investing

Concentrated positions in listed businesses priced below what they are worth. The work is fundamental: cash generation, balance-sheet strength and the durability of an advantage, judged across sectors and industries rather than by index weight. A position is held while the thesis holds, and sized by conviction.

03 / 03

Rates & Macro

Treasuries and high-grade government bonds held for ballast, with interest-rate and total-return swaps used to position the yield curve with precision. Macro views are expressed across sectors and revised as the cycle turns, and duration and credit quality are kept deliberate rather than incidental.

Context

Scale meets the market. Few beat it.

These are the annualised net returns of some of the largest funds in the world, set against the index they are measured by. The pattern is consistent: past a certain size, the cost of moving capital pulls a return back toward the market. The figure at the top is our own.
Beneath The Surface

Every allocation rests on infrastructure built in house.

How We Operate
I.

Risk before return

Position sizing starts from what can be lost, not from what might be gained. Drawdown control is a design constraint, not a reaction.

II.

Data before narrative

Stories follow prices. Positioning, flow and filings move first, so the research process starts there and ends there.

III.

Duration before momentum

The office is built to hold through cycles. Infrastructure, capital base and temperament are aligned to the long term.

We take every position with conviction and stand behind it.
People
The office is led by its founder, with research, allocation and the systems behind them kept under one roof.

Bernardo Ascensão

Founder

The office was founded by Bernardo Ascensão, who oversees research, allocation and the systems the office runs on. Judgement and execution are kept together rather than separated across desks.
