How to read your result
Averaging down (buying more at a lower price to reduce your average cost) only helps if the stock eventually recovers โ it doesn't change the underlying investment thesis, and adding money to a declining position without a fundamental reason to believe in a recovery is a common way to turn a manageable loss into a larger one.
โ ๏ธ Common Mistakes
โ Averaging down repeatedly on a stock without reassessing why it keeps declining.
โ A lower average cost doesn't fix a broken investment thesis โ before adding more money, revisit why you believed in the stock originally and whether that reasoning still holds.
โ Treating a lower average cost as guaranteed to reduce risk.
โ Averaging down increases your total exposure to the same stock โ it concentrates risk rather than reducing it, even though the per-share cost basis looks better on paper.
