$NVIDIA (NVDA.US)$ $Tesla (TSLA.US)$
Originally, last week the return was close to 29%, but it was pulled down to -90% by gamblers' tactics on Friday. After thinking about it, the conclusion is as follows:
1. Intraday may not return to the moving average (considering factors: trend, intraday volume)
2. On Fridays, expiring options walls will be difficult to break through
3. The gambling strategy is not feasible, currently with 4 occurrences, win rate: 0%.
4. Going against the trend poses higher risks, so buying and selling points need to be chosen carefully.
5. Although it involves small capital, a certain level of position management is still necessary. Options positions cannot exceed 70%, out-of-the-money short-term options (expiring within a week) cannot exceed 50%, same-day expiry options cannot exceed 5%. Setting position limits is mainly to prevent risks from escalating due to unrestricted position increases.
