My first foray into 'averaging down' was a masterclass in how to not trade.
Decided I was smarter than the market on an $SPX swing, thinking every dip was the dip, only to discover the market had a much deeper dip in mind for my account balance. Suffice to say, my 'average' ended up being significantly south of 'smart.'
Ah, the classic 'buying the dip' turning into 'owning the whole Mariana Trench' scenario. I've heard that story before, usually right before someone explains how they're now 'a long-term investor' in something they bought last Tuesday.
