Know your number.
Hone turns your investment opinions into disciplined position sizes.
You have views about companies — but no rigorous way to decide what those views are worth in your portfolio. Hone measures the risk you can actually tolerate, converts each belief into mathematically coherent portfolio weights, and lets you test the result safely with paper trading. No real money, no sales pitch.
The problem
Every tool you have stops one step short of a decision.
Your brokerage
Shows you data and charts, then leaves the sizing decision — the decision that actually determines your outcome — entirely to gut feel.
Robo-advisors
Put you in a generic bucket and ignore everything you believe about specific companies.
Spreadsheets
Compute whatever you tell them — but they don't know how much risk you can genuinely stomach when the market falls.
How it works
Measure your risk number
30 quick either/or choices (a classic economics experiment) pin down your personal risk-aversion parameter — no self-flattering "aggressive investor" checkboxes. You land in one of 50 tiers.
Say what you believe
"I think TSLA reaches $220 within a year, and I'm 60% sure." That's a view. Add as many as you have — or none.
Get position sizes
Hone blends your views with market equilibrium and returns exact portfolio weights, a buy/sell list in dollars, a reason for every trade, and a hedge plan if you're carrying more risk than your number allows.
What the output looks like
| Action | Position | Change | Why (short version) |
|---|---|---|---|
| BUY | TSLA | 4% → 35% | your view, at 60% trust, earns this much |
| BUY | AAPL | 7% → 30% | rises with the view via correlation |
| SELL | MSFT | 45% → 0% | risk it adds isn't paid for at your tier |

Built to be trusted, not just believed
Is this real money?
No. Hone connects only to Alpaca's paper-trading API — simulated portfolios with fake money. It cannot place real trades or move real funds, by design.
Can you access my brokerage?
No. Paper-trading keys stay in your browser and are sent only with your own requests. The server never stores them, and they're never written to any database.
What do you store?
Nothing, unless you create an account — then only your risk number, tier, and saved views, so you can reload them. Never credentials, never balances.
How does the math work?
Standard, published methods — the same canon institutions use: experimental risk elicitation, covariance shrinkage, equilibrium-blended views, mean-variance optimization. Every model is named and explained in the walkthrough.
Why should I trust the output?
Don't — verify it. The evidence page runs a no-look-ahead backtest comparing Hone's method against common alternatives, and every recommendation shows its reasoning.
What are the limits?
Models estimate; they don't guarantee. Expected returns are uncertain, covariances drift, and option cost estimates are indicative rather than executable quotes. Hone is decision support, not investment advice.
