Investment Strategy Fit / 投资策略适配

Investment strategy fit is the behavioral and methodological warning from A股的春夏秋冬：种树、种粮、种菜: an investment method only works when the entry reason, evidence, time horizon, position size, and exit rule belong to the same system. [[WuWeizhi|吴伟志]] compares value, growth, and trend methods to different sports, arguing that famous maxims become dangerous when moved into the wrong game.

The source’s strongest example is the investor who buys because of trend, then falls back on [[ValueInvesting|value-investing]] language after the price drops. That mismatch turns a tactical trade into a rationalized hold and makes losses look like conviction rather than a broken process. The reverse error can also happen when a long-term company thesis is abandoned because short-term momentum weakens.

This concept extends Investment Style Map / 投资流派地图 and Multi-Strategy Allocation. The point is not that investors must use only one method forever; it is that each sleeve needs explicit rules, so Growth Investing / 成长投资, Value Investing, Trend Following, quant, and allocation do not overwrite one another at the worst moment.

Key Claims

  • Strategy labels are not enough; the investor needs a matching evidence standard and invalidation rule.
  • A slogan can be true inside one method and false inside another.
  • Mixing methods becomes most dangerous after losses, when the investor is tempted to protect identity instead of reviewing the original reason.
  • Multi-strategy portfolios need separated sleeves, logs, and sizing rules so style diversification does not become ad hoc switching.
  • Personal competence is part of fit: “independent thinking” is only useful when the investor has enough research depth to disagree well.
