GlXY would be a good example for me.
Thanks
Position sizes need to depend on personal risk tolerances and other factors. Generally, we like to trim when exposure makes us nervous. For large caps, we would see 7% as the point at which WE start to get antsy. For smaller companies such as GLXY, 4% or 5%. To note, it is about 5% in our Growth Model right now. Other than for portfolio management reasons, we like to see when something has 'changed', i.e the company adds debt, management leaves, it misses multiple quarters, or something else deemed to be negative for a period of time (not just one quarter). GLXY is more difficult as it is closely tied to cryptocurrencies, which of course are volatile. One guideline is to 'sell some when the position size or other events 'start to make one lose sleep'.
