Buffett always keeps ample cash!
When you see a decline, you get scared, because you have little cash; when Buffett sees a decline, he is happy, because he has ample cash. So, I always advise everyone to invest spare money, and you must never be fully invested without cash flow. Cash and cash flow can cover any decline or major drop.
Therefore, controlling your position is a great science. Remember, when buying a position, you should buy in batches, buy multiple times, and buy slowly; you must never go all in at once. Some say: Those who are afraid to go all in are insecure people. I say: Those who go all in are immature people.
