This may be hard to answer since you've been in the business 30+ years. No matter how many times I start reading about options, I seem to have a mental block about the meaning of put and call.  One's a right to buy, the other's a right to sell. Do you know of any mnemonics that I could employ to remember which is which?

Interesting question.

Perhaps this will work for you:
  • When you CALL stock, it's like your dog and it comes running to you (your account and thus, you buy it).
  • When you PUT stock, you put (or place) it where you want it to go - and that someplace is out of your account and into someone else's account.
