Order matters: when your bad year happens decides your fate

Two traders both average a 10% annual return over five years. Trader A has years: +30%, +20%, +10%, 0%, -10%. Trader B has the SAME returns in reverse: -10%, 0%, +10%, +20%, +30%. Same average. Same returns. Different order. If neither one adds or withdraws money, their FINAL balance is the same — that's how multiplication works. But their EXPERIENCE is wildly different, and that's where sequence-of-returns risk lives.

Wick compares Trader A, who starts with +30%, and Trader B, who starts with -10%, using the same five years in reverse order, showing order changes the experience.Trader A+30, +20, +10,0, -10. Startshot.Trader B-10, 0, +10,+20, +30.Starts cold.
Wick saysSame returns in a different order end at the same balance but feel very different.

Trader A starts hot and feels like a genius — but then deals with a flat and losing year at the end after they've been compounding. Trader B starts with a loss, feels like a failure, and might QUIT before they ever see the +30% year. The math says they end up identical. The psychology says only Trader A actually survives. This is why most retail trading careers end in year one: not because the strategy didn't have edge, but because the trader couldn't endure the order their losses came in.

Wick looks worried under a fear cloud thinking about quitting after a losing first year, showing how early drawdowns end careers through behavior, not math.Year one, down 10%.Maybe I should justquit?
Wick saysAn early loss can make you quit before the good years ever arrive.

Sequence-of-returns risk gets worse when you add cash flows. A new trader who adds $100 to their $500 account every month doubles down on early losses. If they're down 40% at month three and they keep adding, they're throwing fresh money at a losing system. Same math, different impact: every dollar deposited near the trough buys 'cheap' if the system recovers, but feels devastating if the trader is questioning the strategy. The fix: start small, size for survival in year one, scale only after you've actually traded through real conditions.

Wick walks a winding road from Start small to Size to last, with Scale later at the finish flag, showing year one is the survival year.Start smallSize to lastScale later
Wick saysSize for survival in year one, and scale only after real trading experience.

Recap: same average return + same return set = same end balance, but very different experience based on ORDER. Early drawdowns kill careers via behavior, not math. Year one is the survival year. Size for the worst-possible early sequence.
