Leverage Decay Effect
The leverage decay effect describes the erosion of value in a leveraged position over time due to the compounding impact of daily rebalancing or periodic funding costs. This is particularly prevalent in products that aim to deliver a multiple of a daily index return, where the mathematical nature of percentage changes leads to performance drift.
Even if the underlying asset returns to its original price, the leveraged position may suffer a net loss due to the path-dependency of returns. In the crypto market, this effect is exacerbated by the constant flow of funding fees paid by the leveraged party.
Traders often underestimate how quickly these cumulative costs can degrade capital when markets remain sideways or choppy. Long-term holding of leveraged instruments is generally discouraged due to this structural performance drag.
Recognizing this decay is crucial for maintaining the integrity of a long-term trading strategy.
