Day 29: Correlation — The Invisible Thread Between Two Markets
Correlation is a concept many people gloss over when they first get into forex, but it’s one experienced traders can’t ignore when reviewing their positions.
📌 What is it?
A number between -1 and +1 that describes how closely two markets move together:
+1 = they rise and fall together; -1 = when one rises, the other falls; 0 = they move independently.
A common saying in forex is that when the US dollar strengthens, gold often comes under pressure. But this “inverse relationship” isn’t a hard-and-fast rule. When the whole market rushes for safety, you may see them move together.
🔑 Three practical ways to read it:
1. Spot duplicate positions. If you’re long EUR/USD and long gold at the same time, they may look like two separate trades, but essentially they could both be bets on a weaker US dollar.
2. Watch out for concentrated risk. When correlation rises, all your positions can lose at once—that’s a “correlation crisis.” Diversification works well when markets are calm, but when risk hits, you may discover that your “diversified basket” is really made up of the same thing.
3. Use negatively correlated assets to hedge. Only negatively correlated assets can serve as real insurance. But remember: you have to pay the insurance premium year-round.
⚠️ A major pitfall:
Correlation is a “record of the past,” not a “promise about the future.” The more a market is driven by panic, the more likely correlations are to break down.
📊 A crypto comparison:
BTC, ETH, and US stock indexes often “breathe in sync.” Many people think they’re holding crypto, when in fact they’re holding a high-beta stock position.
If your “diversified portfolio” consists of US stocks, crypto, and the US dollar index, you may ultimately be holding just one thing.
Before opening your next position, ask yourself: How many markets am I really exposed to?
