I love it how everyone around here seems to be "long" and "all in", yet every time we have a dip they seem to have "dry powder" to pick up shares.
Your statement only makes sense for people who trade only in stock, and no cash, and have no disposable income for periodic investments which they can time as they please
Options traders pretty much by definition deal in varying levels of leverage, which change on their own even if you do nothing. So it's not a case of "bought" vs. "not bought", it's a case of "how much leverage do you want at this point in time, and what sort of premiums / theta are you willing to put up with for it?"
