Study the stockbefore you buy it

Takes the stocks you pick and works out the mix that historically gave the best return for the risk taken. It weighs how each stock moves with the others, so the whole is steadier than the parts. (The Markets tab's Correlation Lab shows how any stocks move together — this study builds your mix from it.)

Uses the Kelly formula to work out how big each position should be so the portfolio grows fast without risking a blow-up.

Simulates thousands of possible futures for a portfolio and reads off the bad ones: how much you could lose on a bad day, in a bad month, and how likely deep losses are.

Predicts how rough or calm prices are likely to be over the coming weeks, based on how turbulence has been clustering recently.

Ranks a broad list of stocks by the strength and persistence of their recent price trends, across several time horizons at once.

Blends nine independent signals — trend, momentum, money flow and more — into one score per stock, then tests whether that score actually predicted returns on unseen data.

Studies the benchmark index and classifies the market's current phase — trending up, drifting sideways, or under stress — plus the odds of switching from one phase to another.

Maps every sector by whether it's leading or lagging the market and whether it's gaining or losing steam — the classic four-quadrant rotation view. (The Markets tab shows the whole market's rotation — this study scores your list's.)
