Capital appreciation vs. capital gains
Capital appreciation is typically used to refer to the gains on an investment that you still own, as opposed to investments you’ve sold and collected your profits. In other words, capital appreciation is often associated with unrealized gains. However, capital appreciation can be used to refer to an entire portfolio, which would include both realized and unrealized investment gains.
Once you sell an appreciated asset, it becomes a capital gain, which is important for tax purposes. Under the U.S. tax code, you only have to pay taxes on realized investment processes, not unrealized gains. Regardless of how much your investments have grown in value; you typically won’t have any tax implications until you decide to sell.
It’s also important to point out that it’s entirely possible for an investment to produce negative capital appreciation if its market value declines. If you sell an investment for less than your cost basis, it results in a capital loss. If it’s an investment you still own, it would be referred to as an unrealized loss.
Example of capital appreciation
Let’s say that you own a stock that you purchased for $50 per share three years ago. It currently trades for $75 per share and has paid a total of $10 in dividends since you bought it.
You would have $25 in capital appreciation on the stock, which would correspond to a 50% unrealized gain. You would also have received a 20% overall dividend yield on your cost. Combining these two figures would result in a 70% total return. Many investors like to express returns on an annualized basis to compare the performance of investments with different holding periods, and since you’ve owned the stock for three years, this corresponds to a 19.3% annualized total return.
