How Smooth Strategy Returns Can Hide Averaging-Down Risk
Summary
The note warns that exceptionally high win rates and smooth profit curves can conceal risks, especially in strategies that add to losing positions. It argues that evaluating a strategy requires tracking total account value against a relevant baseline. For a spot portfolio, the suggested baseline is the value of the initial coin holdings at the current price plus the initial cash, so the comparison reflects market movement over time.
It describes two sources of misleadingly smooth results. Grid strategies may report accumulated trading gains without showing whether total portfolio value has fallen, and therefore may depend on suitable timing to start. High win-rate strategies may use countertrend position increases, creating many small wins while risking much larger losses. The author draws on personal experience of losing heavily when adopting others’ strategies. The note does not provide performance data or a formal risk model; it recommends understanding possible losses and matching them to one’s tolerance before using a strategy.
Key ideas
- Evaluate returns by comparing total account value with a baseline that reflects current market prices.
- Grid trading gains can look positive while the portfolio’s total value declines.
- A high win rate may hide countertrend position increases and an unfavorable reward-to-risk profile.
- Assess potential loss size and personal risk tolerance before adopting another trader’s strategy.
