Legal analysis: the state has no policy to restrict the financial behavior of low-income households such as stock trading, but because the qualification of low-income households is judged by family income, if the stock trading income is rich and does not meet the qualification of low-income households, they will no longer enjoy the subsidy policy of low-income households.

Legal basis: Article 2 of the Regulations on Minimum Living Security for Urban Residents holds that non-agricultural registered permanent residence urban residents whose per capita income of family members living together is lower than the minimum living security standard for local urban residents have the right to get basic living material help from the local people's government. The income mentioned in the preceding paragraph refers to all the monetary income and in-kind income of family members living together, including alimony, alimony or alimony that should be paid by legal dependents or dependents, excluding pensions and subsidies enjoyed by entitled groups in accordance with state regulations.
