Understanding Market Volatility

Two flavours of volatility

Realised volatility is calculated from past prices. Implied volatility is extracted from options pricing — the market's forward-looking estimate. The two often disagree, and the disagreement itself is informative.

Reading volatility

• Rising volatility often coincides with falling prices in equities — but not in commodities or crypto.
• Compressed volatility tends to precede expansion. Quiet markets rarely stay quiet.
• Volatility clusters: high-volatility days tend to follow high-volatility days.

What it means for risk

Higher volatility means each unit of position takes on more risk. A fixed-dollar stop in a high-volatility market gets hit much more often. The fix is to size positions using a volatility measure like ATR — see our risk management guide.

Platforms during volatility

Volatile conditions are the real test of a platform. Spreads widen, fills slip, support queues grow. When evaluating environments like BLUMBERG global, the most informative observation is how the platform behaves during the loud moments — not the quiet ones.
