Fed net liquidity
A market-monitoring proxy commonly calculated as Federal Reserve assets minus the Treasury General Account and overnight reverse-repo balances.
It summarizes three large balance-sheet flows that can add or remove dollar liquidity. It is a context indicator, not a guaranteed equity-market signal.
A comparison of a sector investment's price behavior with a benchmark. Sector Strength uses each sector ETF's daily price relative to SPY and normalizes the ratio against its recent history.
Relative outperformance can occur while both prices fall. The chart's index is centered at 100 and is not a percentage return or the Relative Strength Index oscillator.
The change in a sector's strength measure over a stated observation window. Sector Strength uses the ten-session change and normalizes it into an index centered at 100.
It helps distinguish the current level of relative strength from its recent direction. Trails show historical movement, not a projected path or a promise of future returns.
The volatility level embedded in an option price under an option-pricing model.
IV is the market price of uncertainty. Comparing it across strikes, expiries and its own history helps assess whether optionality is relatively rich or cheap.
The position of current implied volatility between its high and low over a selected historical window, often one year.
It gives context to the current volatility level, but one extreme observation can distort the range. The options panel uses a different volatility-rank proxy based on historical realized volatility, as explained on its feature page.
An estimate of aggregate option gamma associated with dealer positioning, inferred from public option data and model assumptions.
The sign and concentration of estimated gamma can help frame whether hedging flows may dampen or amplify price changes. Dealer inventory is not publicly observed, so GEX remains an estimate.
