Another recovery play post covid

Costco just released a strong earning report which proved once again its business model could transcend good and bad time.
If we looked back at the last three years, we could easily observe Costco shares often time dropped the week before earning release, and bounced right back up after. It happened in 2018, 2019 and just now before the earning last week.
Together with the negative sentiments, costco share priced did drop below its uptrend line for a moment, but it managed to climb back above before the weekend, and lets assume its uptrend would continue esp with the recovery play in front of us.
I do not now have a position in Costco but I am looking forward to start a position at 337 (10MA), with its recent low $313 as cut loss and looking for at least an upside target of $390, which gives us a decent 2x of risk reward ratio.
