Is CarMax under- or over-valued?

Valuing CarMax stock is incredibly difficult, and any metric has to be viewed as part of a bigger picture of CarMax's overall performance. However, analysts commonly use some key metrics to help gauge the value of a stock.

CarMax's P/E ratio

CarMax's current share price divided by its per-share earnings (EPS) over a 12-month period gives a "trailing price/earnings ratio" of roughly 27x. In other words, CarMax shares trade at around 27x recent earnings.

That's comparable to, say, the trailing 12-month P/E ratio for the NASDAQ 100 at the end of 2019 (27.29).

CarMax's PEG ratio

CarMax's "price/earnings-to-growth ratio" can be calculated by dividing its P/E ratio by its growth – to give 1.1906. A low ratio can be interpreted as meaning the shares offer better value, while a higher ratio can be interpreted as meaning the shares offer worse value.

The PEG ratio provides a broader view than just the P/E ratio, as it gives more insight into CarMax's future profitability. By accounting for growth, it could also help you if you're comparing the share prices of multiple high-growth companies.


CarMax's EBITDA (earnings before interest, taxes, depreciation and amortisation) is US$1.3 billion.

The EBITDA is a measure of a CarMax's overall financial performance and is widely used to measure a its profitability.

Shorting CarMax shares

There are currently 4.2 million CarMax shares held short by investors – that's known as CarMax's "short interest". This figure is 12.6% up from 3.8 million last month.

There are a few different ways that this level of interest in shorting CarMax shares can be evaluated.

CarMax's "short interest ratio" (SIR)

CarMax's "short interest ratio" (SIR) is the quantity of CarMax shares currently shorted divided by the average quantity of CarMax shares traded daily (recently around 1.2 million). CarMax's SIR currently stands at 3.64. In other words for every 100,000 CarMax shares traded daily on the market, roughly 3640 shares are currently held short.

However CarMax's short interest can also be evaluated against the total number of CarMax shares, or, against the total number of tradable CarMax shares (the shares that aren't held by "insiders" or major long-term shareholders – also known as the "float"). In this case CarMax's short interest could be expressed as 0.03% of the outstanding shares (for every 100,000 CarMax shares in existence, roughly 30 shares are currently held short) or 0.0261% of the tradable shares (for every 100,000 tradable CarMax shares, roughly 26 shares are currently held short).

Such a low SIR usually points to an optimistic outlook for the share price, with fewer people currently willing to bet against CarMax.

CarMax share dividends

We're not expecting CarMax to pay a dividend over the next 12 months.

Have CarMax's shares ever split?

CarMax's shares were split on a 2:1 basis on 26 March 2007. So if you had owned 1 share the day before before the split, the next day you'd have owned 2 shares. This wouldn't directly have changed the overall worth of your CarMax shares – just the quantity. However, indirectly, the new 50% lower share price could have impacted the market appetite for CarMax shares which in turn could have impacted CarMax's share price.

CarMax share price volatility

Over the last 12 months, CarMax's shares have ranged in value from as little as US$84.7 up to US$138.66. A popular way to gauge a stock's volatility is its "beta".

KMX.US volatility(beta: 1.65)Avg. volatility(beta: 1.00)LowHigh

Beta is a measure of a share's volatility in relation to the market. The market (NYSE average) beta is 1, while CarMax's is 1.6538. This would suggest that CarMax's shares are more volatile than the average for this exchange and represent, relatively-speaking, a higher risk (but potentially also market-beating returns).
