Portfolio Management for Active Traders

Position sizing and stop-losses manage the risk of one trade in isolation, but an active trader is often running several positions at the same time, and portfolio management is about managing the combined risk of all of them together. The core problem it solves: five separate trades that each individually risk 2% can still add up to a much bigger combined exposure than 10% if they're not independent of each other.

Correlation is the key concept here. Two trades in currency pairs that both depend heavily on the US dollar, or two trades in commodities that both move with the same risk-on/risk-off sentiment, aren't really diversified -- a single macro event can move both against the trader at the same time. Portfolio-level risk management means checking how correlated open positions are and reducing individual position sizes when several correlated trades are open together, so total account risk stays within a set limit regardless of how many trades are running.

Exposure limits are the practical tool for this: caps like "no more than 6% of the account at risk across all open positions at once" or "no more than two correlated positions open at the same time" keep a string of individually reasonable trades from combining into an unreasonable total bet. This is distinct from -- and sits on top of -- the per-trade risk rules from earlier lessons.

For traders running multiple strategies or automated systems at once (bots, copy-trading follower accounts, or a mix of manual and automated positions), portfolio management also means tracking these as one combined risk picture rather than monitoring each system in isolation, since it's the combined drawdown across everything running that actually threatens the account.
