Upside caps vary based on market conditions, your stock's volatility, and your chosen protection level. In recent examples, an 80% floor has paired with caps around 145-160%, meaning you participate in gains of approximately 45-60%.
The cap is the trade-off for downside protection. If your stock appreciates beyond the cap during the contract term, you won't participate in gains above that level. This opportunity cost is worth weighing carefully, especially if you have strong conviction in your stock's near-term growth.
