Frequently Asked Questions
What is dollar cost averaging?
Dollar cost averaging (DCA) means investing fixed amounts at regular intervals regardless of price. This reduces the impact of volatility and eliminates the stress of trying to time the market perfectly.
Should I average down on losing positions?
Averaging down can be a valid strategy if you still believe in the investment thesis. However, never throw good money after bad. Evaluate why the stock declined before adding more. Consider position sizing limits.
How is average cost calculated?
Average cost = Total Amount Invested / Total Shares Owned. For example, buying 10 shares at $50 and 10 shares at $40 gives you 20 shares with $900 invested, for a $45 average cost.
Why does cost basis matter for taxes?
Your cost basis determines capital gains when you sell. Higher cost basis means lower taxable gains. In the US, you can use specific identification, FIFO, or average cost methods depending on the account type.
Is averaging down the same as catching a falling knife?
Not necessarily. Averaging down into quality companies during market corrections can be profitable. 'Catching a falling knife' usually refers to buying declining stocks without fundamental analysis. Always have a thesis.
