问题如下：
Momentum, can be partly explained by the following behavioral biases except:
选项：
A.availability.
home bias.
regret.
解释：
B is correct.
Home bias refers to FMPs preferentially investing in domestic securities, likely reflecting perceived relative informational advantages, a greater feeling of comfort with the access to company executives that proximity brings (either personal or through a local brokerage), or a psychological desire to invest in a local community. Momentum, on the other hand, has been documented in a range of markets around the world, in a time-dependent manner, and reflects some FMPs’ availability bias, manifested as a belief that stocks will continue to rise because recently they have only risen, as well as regret aversion by those who invest in past winners because they regret not investing in them in the past.
这道题的题干什么意思啊，讲义里并没有讲到home bias
