What investment strategy is this called? (if it even has a name)

I am currently investing by ‘locking in’ my portfolio value, such that when the market makes my portfolio go above, say, $100, i would not sell, but every time it ends lower than $100, i buy to make it exactly $100.

I do this since my portfolio is currently 33%-40% Marijuana stocks. Making me expect the portfolio to go down on average.

The goal is to make the effect of a wind-up, investing during losses and letting it do its thing if it were to ‘release’ with some sort of weed legalization or descheduleing.

I wouldn’t call this dollar cost averaging or averaging down since by nature the buying is only proportional to how much is lost that is below the amount that i set.
