BLK BlackRock Options Ahead of Earnings

If you haven`t sold BLK here:

and bought it here:

Then analyzing the options chain of BLK BlackRock prior to the earnings report this week,
I would consider purchasing the 730usd strike price Calls with
an expiration date of 2023-7-21,
for a premium of approximately $6.20.
If these options prove to be profitable prior to the earnings release, I would sell at least half of them.

Looking forward to read your opinion about it.

Trade closed: target reached:

BLK has reached $744.00 after the earnings in the first 5 minutes of trading.
The calls were up more than 2X!
However, if you hadn't closed and kept the position before the market close, they started to become unprofitable. Options are dynamic and constantly change in price. That's why I sell the winning contracts after the earnings in the first 5 minutes of trading, while the volatility helps me get a better price.
