英文摘要:
We show that when the price process $S$ represents a fully incomplete market, the optimal super-replication of any Markovian claim $g(S_T)$ with $g(\\cdot)$ being nonnegative and lower semicontinuous is of buy-and-hold type. Since both (unbounded) stochastic volatility models and rough volatility models are examples of fully incomplete markets, one can interpret the buy-and-hold property when super-replicating Markovian claims as a natural phenomenon in incomplete markets.

中文摘要:
我们证明,当价格过程$S$代表一个完全不完全市场时,任何马尔可夫索赔$g(S\\T)$与$g(\\cdot)$为非负且下半连续的最优超复制都是买入持有型。由于(无界)随机波动率模型和粗糙波动率模型都是完全不完全市场的例子,因此,当超级复制马尔可夫索赔时,可以将买入并持有资产解释为不完全市场中的一种自然现象。
