Add your strategies
Step 1Drop in your first strategyUpload or drag a trade log or equity curve CSV anywhere onto this card. Add up to 8 sleeves to compare and allocate. Not sure where to start? Load three example strategies and explore the whole tool.
Strategy report
Step 3Strategy reportThe same grade a backtest gets, your trades drawn on the market they traded, and which market conditions the edge actually survived, for a single strategy before there is a portfolio to build.
Allocate
Step 3AllocateSolve weights across your sleeves equal weight, inverse-vol, risk parity, min-variance, max-Sharpe always shown against equal weight, never a bare optimizer result.
Composed curve
Step 4Composed curveYour blended portfolio equity curve, with rebalancing schedule and cost applied, plotted against every sleeve and the rebalance drag reported as its own number.
Risk
Step 5RiskThe correlation matrix, each sleeve’s share of portfolio volatility (not its weight), your deepest drawdowns with recovery times, and the efficient frontier.
Validate
Step 6ValidateWalk forward and Monte Carlo stress tests the honest out of sample picture against equal weight and the best single sleeve, not the in sample fit.
Keep it
Step 7Nothing to keep yetBuild a portfolio above, then save it, share a card, or export the weights. Everything up to here is free; an email only unlocks keeping a copy.
Every calculation runs in your browser, and your file never leaves your device. Three things reach our servers, each only when you ask: turning on real terms fetches US CPI; charting a strategy sends its symbol and date range to look up prices; and running a strategy report sends each trade’s dates and profit to be graded. Your file, your column names, and every other number stay in the browser. Portfolio Lab is a free tool from Spekule; results are for research and are not investment advice.
