Should I DCA into Deere?

I’m a 23 year old with 10k sitting in savings doing nothing. Originally this was my goal amount to have for emergencies but now I’m considering investing it due to inflation buying away at its value. I really like Deere but it seems expensive with all the recent run ups it has had and some insiders selling.

In your opinion, should I:

A) Dollar cost average into Deere, 100 dollars per week until 5k is invested

B) Hold on to the savings and invest more slowly into Deere

C) Dollar cost average in to Deere, Cat, and $moo at $50 a week each until 5k is invested

D) other, elaborate

I am aware nobody knows the correct answer, I will do my own DD and accept responsibility if it backfires, just wanted your opinion. Thanks in advance
