BLK BlackRock Options Ahead of Earnings

If you haven`t sold BLK here:

or ahead of the previous earnings:

Then analyzing the options chain and the chart patterns of BLK BlackRock prior to the earnings report this week,
I would consider purchasing the 640usd strike price Puts with
an expiration date of 2023-10-13,
for a premium of approximately $10.80.
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.
