Process

Five steps from thesis to trade

No coding. No Bloomberg terminal. No 9:30am alarm. Just write what you believe and let PIA execute it.

Write your thesis

Plain English investment conviction — what you believe about the market over the next 12–24 months.

Set allocation

Choose $50–$500 per week or month. This is the maximum PIA can deploy per cycle.

Set guardrails

Position size limit, stop-loss threshold, sector exclusions. Hard-enforced before any order is placed.

Agent executes

Every Monday 9:45am ET — Claude reads your thesis, checks market conditions, selects and places trades.

Read the reasoning

Every trade comes with Claude's plain-English explanation. Full audit trail. No black box.

Why PIA

Two value propositions. One product.

PIA is valuable on two independent dimensions — either one alone would justify building it.

🧠

Superior pattern recognition

An LLM can identify correlations across geopolitical events, earnings data, macro cycles, sector rotations, and news sentiment simultaneously — at a breadth no individual analyst can match. It runs all the threads in parallel, every execution cycle.

Iran conflict → oil supply risk → energy rotation → risk-on momentum → broad market bid. A human analyst covers one thread. PIA runs all of them.

⚡

Emotion-free execution

The agent executes your thesis consistently every week — without panic-selling on a red Tuesday, FOMO-buying after a 30% run, or revenge-trading after a loss. The dollar allocation cap is the product's built-in risk circuit breaker.

The agent is not smarter than the market. It is more consistent than the investor. That consistency, compounded over time, is the value.

Risk Management

Guardrails baked into the product

Risk controls are enforced in the Worker code — not just advisory. Claude cannot bypass them.

🛡

Weekly allocation cap

$100/wk

Maximum the agent can deploy per execution cycle. The known, affordable risk limit baked into the product design itself.

📊

Position size limit

20% max

No single holding can exceed 20% of the portfolio. Hard-enforced before the order reaches Alpaca. Claude cannot override this.

🔴

Stop-loss enforcement

−15%

Any position down more than 15% is automatically liquidated at the start of the next execution cycle. Proceeds returned to cash.

🏦

Cash account only

No margin

Cash account type avoids the Pattern Day Trader rule. No leverage. No margin calls. You can only lose what you put in.

📋

Asset class restriction

US equities

NYSE and NASDAQ equities only in Phase 1. No options, no leveraged ETFs, no crypto. Enforced via Claude's system prompt.

⏸

One-tap pause

Instant

Toggle from the dashboard stops all future executions immediately. Existing positions stay open. Resume at any time.
