How should risk‑adjusted position sizing be modified in response to this development?

Risk‑adjusted position sizing should be tightened.

The class‑action filing adds a fresh, material legal head‑risk to LINE’s fundamentals and is already reflected in a sharply negative sentiment score (‑75). Expect heightened downside‑bias and a widening of the bid‑ask spread as market participants re‑price the potential liability exposure. In a risk‑adjusted framework this translates into a higher volatility‑adjusted “risk‑per‑share” metric (e.g., a larger standard‑deviation‑based stop‑loss distance or a higher implied‑volatility premium). Consequently, the optimal position size – whether calculated via a fixed‑fraction, Kelly, or volatility‑targeting model – should be reduced by roughly 30‑50 % relative to the pre‑news allocation, to keep the dollar‑risk per trade within the trader’s overall risk budget.

Implementation tip:

If you normally risk 1 % of capital on a LINE trade with a 5 % volatility‑based stop, cut the capital‑risk to 0.5 % (or halve the number of shares) and widen the stop to accommodate the expected increase in volatility. This smaller, more conservative sizing preserves capital while still allowing you to stay positioned for any short‑term price moves that may arise from the lawsuit’s progression.
