What is Deep Value Investing: Answers to the Most Common Questions
What is deep value investing? It is the strategy of buying stocks that trade at extreme discounts to their intrinsic value, specifically at prices well below what the underlying assets or earnings justify. Deep value investors do not need a business to grow. They need the price to be low enough that they are protected against a range of bad outcomes. Benjamin Graham pioneered the approach, Warren Buffett deployed it in the 1950s to generate 29%+ annual returns, and academic research has continued to confirm that deeply discounted stocks outperform the market over 5-10 year holding periods when held in diversified portfolios.
Key Takeaways
- What is deep value investing: buying stocks at extreme discounts, typically P/B below 0.8 or prices below net current asset value, where the price paid provides a large margin of safety.
- The strategy does not require earnings growth. It requires that the price is low enough to protect capital even if business conditions remain poor.
- Deep value works best when fear and neglect drive prices far below fundamentals, in bear markets, distressed sectors, and under-followed micro-caps.
- Single deep value stocks are volatile and risky. Portfolios of 20-30 names historically produce the reliable above-market returns the strategy is known for.
- The ValueMarkers screener offers filters for P/B, earnings yield, and NCAV ratio, the three primary deep value entry metrics.
What Makes Deep Value Different from Standard Value Investing?
Standard value investing buys quality businesses at a modest discount to fair value. Deep value investing buys any business, quality or not, at an extreme discount to asset value or earnings. The price discount is so large that quality becomes a secondary concern.
Apple (AAPL) at a P/E of 28.3 and ROIC of 45.1% is a high-quality business at a modest premium. A standard value investor might buy it. A deep value investor ignores it: the price premium to intrinsic value leaves no margin of safety at the extreme end of the spectrum.
A deep value candidate looks different: a small industrial distributor with a P/B of 0.6, zero long-term debt, cash covering 40% of its market cap, and an earnings yield of 14%. The business is unglamorous, but the price paid is so low that it does not need to perform well. It just needs to not collapse.
| Dimension | Standard Value | Deep Value |
|---|---|---|
| Minimum business quality | Good to excellent | Any (often mediocre) |
| Price-to-book target | 1.0-2.5x | Below 0.8x |
| Earnings yield target | 6-10% | Above 12% |
| Growth requirement | Modest positive | None required |
| Typical holding period | 2-5 years | 3-7 years |
| Portfolio diversification | 10-20 names | 20-40 names |
What Time Does the Stock Market Open?
U.S. equity markets, including the NYSE and Nasdaq, open at 9:30 a.m. Eastern Time and close at 4:00 p.m. Eastern Time on weekdays. Pre-market trading begins as early as 4:00 a.m. Eastern and after-hours trading runs until 8:00 p.m. Eastern, though volume and liquidity are significantly lower outside regular hours. Deep value investors are typically unconcerned with intraday timing; their holding periods are measured in years, not hours.
What Time Does the Stock Market Close?
The U.S. stock market closes at 4:00 p.m. Eastern Time on weekdays. Early closings occur on the afternoon before major holidays, when markets often close at 1:00 p.m. Eastern. For a complete list of market closures and early closes, the NYSE and Nasdaq publish official holiday schedules on their websites each year.
Are Stock Markets Closed Today?
U.S. markets observe nine federal holidays each year: New Year's Day, Martin Luther King Jr. Day, Presidents' Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving, and Christmas Day. When those dates fall on weekends, markets close on the nearest Friday or Monday. You can check current market status at any major financial data provider or through the NYSE's official calendar.
What Happens If the Stock Market Crashes?
A stock market crash creates some of the best opportunities for deep value investors. When the market falls 30-50%, many high-quality businesses trade at prices below book value or net current asset value, metrics that rarely reach those extremes outside a crisis. Deep value investors with cash reserves deploy capital systematically during crashes rather than retreating. During the 2008-2009 crash, diversified portfolios of stocks at deep discounts to book value purchased near the March 2009 lows returned 300-500% over the following decade. The crash was the opportunity, not the risk, for investors who had prepared their portfolios in advance.
Why Is the Stock Market Down Today?
Daily market moves reflect changes in investor sentiment, interest rate expectations, economic data releases, and company-specific news. Short-term market declines are normal and expected. From 1928 to 2025, the U.S. stock market has experienced a 10%+ correction in roughly 75% of all calendar years. Deep value investors treat these declines as price-setting opportunities rather than signals to act defensively. When market prices fall, the discount between price and intrinsic value typically widens, making entry conditions more attractive.
Is Coca-Cola a Good Stock to Buy?
Coca-Cola (KO) is not a deep value stock by any standard definition. KO trades at a P/E near 24 with a dividend yield of 3.0%. From a deep value perspective, it does not trade near book value and does not approach NCAV territory. However, KO has grown its dividend for over 60 consecutive years and carries one of the most durable brand franchises in consumer goods. Quality-value investors treat KO as a core dividend-growth holding rather than a deep value play. Whether it belongs in your portfolio depends on your strategy: KO fits a dividend income or quality compounding approach, not a Graham-style asset-based deep value screen.

Frequently Asked Questions
what happens if the stock market crashes
A market crash is a rapid decline in prices, typically defined as a drop of 20% or more. For deep value investors, crashes are buying opportunities because fear drives prices to extreme discounts relative to fundamental value. Investors with predefined criteria and cash reserves can deploy capital systematically. The 2009 and 2020 market lows produced the best entry points for deep value strategies in a generation. The key is preparing the list of target stocks before the crash, so you can act quickly when prices fall to your thresholds.
what time does the stock market open
The New York Stock Exchange and Nasdaq open at 9:30 a.m. Eastern Time on Monday through Friday, excluding federal holidays. Pre-market sessions run from approximately 4:00 a.m. Eastern. For deep value investors, exact market open timing is less relevant than annual rebalancing cycles, since deep value strategies operate on multi-year holding periods rather than short-term trading windows.
what time does the stock market close
U.S. equity markets close at 4:00 p.m. Eastern Time on weekdays. After-hours trading runs until 8:00 p.m. Eastern with reduced volume. The NYSE and Nasdaq publish their holiday schedules annually with any early-close dates, typically the afternoons before Thanksgiving and Christmas. Again, for deep value investors, close-of-day prices matter only at annual rebalancing or when a specific catalyst triggers a position review.
why is the stock market down today
Daily market declines reflect short-term changes in sentiment, macro data surprises, interest rate adjustments, or individual company news. For deep value investors, a down day is worth examining only to check whether any target stocks have crossed below predefined entry thresholds. A stock you have been monitoring at a P/B of 0.9 that falls to P/B 0.75 during a sell-off is now at a more attractive entry price. The reason for the market-wide decline matters less than whether individual prices have moved into deep value territory.
what time does stock market open
The U.S. stock market opens at 9:30 a.m. Eastern. International markets operate on different schedules: the London Stock Exchange opens at 8:00 a.m. GMT, the Tokyo Stock Exchange at 9:00 a.m. JST, and the Hong Kong Stock Exchange at 9:30 a.m. HKT. Deep value investors who screen international markets, particularly Japanese equities where net net stocks are more abundant than in the U.S., need to account for local market hours and currency considerations.
is coca cola a good stock to buy
Coca-Cola is a high-quality dividend-growth stock rather than a deep value play. KO's P/E of approximately 24, dividend yield of 3.0%, and 60+ year dividend growth streak make it a standard holding for income-focused or quality-value investors. Deep value investors applying Graham-style NCAV or book value criteria would not screen for KO at current prices. If your strategy focuses on dividend income, brand durability, and capital preservation, KO has a strong track record. If your strategy targets extreme discounts to asset value, the current price does not qualify.
Use the ValueMarkers screener to set a P/B filter below 0.8 and an earnings yield above 12%, the two primary entry signals for deep value candidates. The screener covers 120+ indicators so you can layer in quality and risk filters to separate the genuine opportunities from the traps.
