Net-net working capital investing

1. Net-Net Working Capital Investing

Net-Net Working Capital (NNWC) investing is a value investing strategy popularized by Benjamin Graham, the father of value investing, in his 1973 book, "The Intelligent Investor." It focuses on identifying companies trading at a price below their net current asset value, essentially meaning you can buy the entire company and liquidate its current assets (cash, accounts receivable, and inventory) and still have money left over after paying off all current liabilities (accounts payable, short-term debt, etc.). This approach is considered a deeply conservative strategy, aiming to minimize downside risk. This article will provide a comprehensive overview of NNWC investing, covering its principles, calculation, historical performance, advantages, disadvantages, screening criteria, and practical considerations for implementation.

Core Principles

At its heart, NNWC investing is based on the principle of a *margin of safety*. Graham believed that investors should only purchase stocks when they are trading significantly below their intrinsic value. NNWC provides a very tangible and conservative measure of intrinsic value. The idea is that even if a company’s future earnings are uncertain or negative, its net current asset value represents a floor for its price. If the market prices a company below this floor, it suggests a significant mispricing.

The strategy relies heavily on the concept of *liquidation value*. Graham posits that inefficient markets sometimes undervalue companies, and in extreme cases, a buyer could purchase the company, sell off its current assets, pay off its debts, and pocket the difference as a profit – regardless of the company’s long-term prospects.

This is not to say that investors *expect* to see companies liquidated. Rather, the deep discount to NNWC provides a substantial cushion against errors in earnings forecasts or unexpected business difficulties. Many NNWC stocks will eventually recover and resume normal operations, providing investors with a substantial return.

Calculating Net-Net Working Capital

The calculation of NNWC involves several steps, and accuracy is crucial. Here's a breakdown:

1. **Current Assets:** Identify all current assets on the company’s Balance Sheet. This typically includes:

   * Cash and Cash Equivalents
   * Accounts Receivable (Net of Allowance for Doubtful Accounts)
   * Inventory (Valued at the lower of cost or market)
   * Prepaid Expenses
   * Other Current Assets

2. **Current Liabilities:** Identify all current liabilities on the Balance Sheet. This typically includes:

   * Accounts Payable
   * Short-Term Debt
   * Accrued Expenses
   * Deferred Revenue
   * Current Portion of Long-Term Debt
   * Other Current Liabilities

3. **Net Current Asset Value (NCAV):** Calculate NCAV by subtracting total current liabilities from total current assets:

  NCAV = Total Current Assets – Total Current Liabilities

4. **Net-Net Working Capital (NNWC):** Calculate NNWC by subtracting total liabilities (both current and non-current) from total assets.

  NNWC = Total Assets - Total Liabilities

  However, Graham often focused on a more conservative measure, the *Net Current Asset Value* (NCAV) and compared the market capitalization to that. For simplicity, we’ll primarily focus on NCAV in this article.

5. **NNWC per Share:** Divide the NCAV by the number of outstanding shares to arrive at the NNWC per share:

  NNWC per Share = NCAV / Number of Outstanding Shares

6. **Margin of Safety:** Compare the NNWC per share to the current market price per share. Investors typically seek a significant margin of safety, often 33% to 66% below the NNWC per share. For example, if the NNWC per share is $10, an investor might only consider purchasing the stock if it's trading at $6.67 or less (33% margin of safety) or $3.33 or less (66% margin of safety).

It’s important to use the most recent financial statements available. Remember to adjust for any potential accounting irregularities or off-balance sheet liabilities. Financial Statement Analysis is a critical skill for successful NNWC investing.

Historical Performance

Empirical studies have shown that NNWC stocks have historically outperformed the overall market with significantly lower volatility. Research conducted by Warshaw, Graham, and Dodd, and later by other academics, demonstrated that a portfolio of deeply undervalued NNWC stocks generated substantial returns over long periods, particularly during the 1930s and 1970s.

While past performance is not indicative of future results, the historical success of NNWC investing suggests that it can be a viable strategy for patient, long-term investors. However, it's crucial to note that identifying true NNWC stocks has become more challenging in recent decades due to changes in accounting practices and increased market efficiency. Market Efficiency plays a crucial role in identifying undervalued stocks.

Advantages of NNWC Investing

• **High Margin of Safety:** The primary advantage is the substantial margin of safety provided by the undervaluation. This reduces the risk of permanent capital loss.
• **Conservative Approach:** It’s a highly conservative strategy that focuses on tangible assets rather than speculative growth prospects.
• **Downside Protection:** The liquidation value provides a floor for the stock price, limiting potential losses.
• **Potential for High Returns:** While conservative, the strategy can generate significant returns when the market recognizes the undervaluation.
• **Independent of Earnings:** The strategy is less reliant on earnings forecasts, making it more resilient to economic downturns. Understanding Economic Indicators can still be beneficial for timing.

Disadvantages of NNWC Investing

• **Rarity of Opportunities:** True NNWC stocks are increasingly rare, requiring extensive screening and patience.
• **Illiquidity:** NNWC stocks are often small-cap or micro-cap companies, which can be illiquid, making it difficult to buy or sell large positions without affecting the price. Understanding Order Book Dynamics is helpful.
• **Potential for Value Traps:** Some companies may be trading at low valuations for valid reasons, such as declining industries or poor management. Thorough Due Diligence is essential.
• **Long Holding Periods:** It can take a considerable amount of time for the market to recognize the undervaluation, requiring a long-term investment horizon.
• **Accounting Complexity:** Accurately calculating NNWC requires careful analysis of financial statements and an understanding of accounting principles.
• **Risk of Delisting:** Companies trading at extremely low valuations may be at risk of delisting from exchanges.
• **Limited Growth Potential:** Many NNWC companies are in mature or declining industries. Industry Analysis is crucial.

Screening Criteria for NNWC Stocks

Identifying potential NNWC candidates requires a systematic screening process. Here are some common criteria:

• **NCAV Test:** Market Capitalization < NCAV (or NNWC). This is the primary screening criterion. A common threshold is a market cap less than 66% of NCAV.
• **Debt Levels:** Total Liabilities < Total Assets. This ensures the company is not overly burdened with debt.
• **Positive Tangible Assets:** Total tangible assets should be positive and significant.
• **Avoidance of Complex Structures:** Avoid companies with complex financial structures, such as holding companies or those with significant off-balance sheet liabilities.
• **Reasonable Current Ratio:** A current ratio (Current Assets / Current Liabilities) of at least 1.0, indicating the company can cover its short-term obligations. Analyzing the Current Ratio is vital.
• **Small to Micro-Cap Size:** NNWC stocks are typically found among smaller companies.
• **Avoidance of Bankruptcy Risk:** Screen for companies that are not on the verge of bankruptcy. Reviewing Credit Ratings can be helpful.
• **No Significant Litigation:** Avoid companies involved in major legal disputes that could jeopardize their financial stability.
• **Simple Business Model:** Prefer companies with relatively simple and understandable business models. Porter's Five Forces analysis can be useful.
• **Management Integrity:** Assess the quality and integrity of the company's management team. This is more subjective but critical.

Practical Considerations and Implementation

• **Data Sources:** Reliable financial data is essential. Sources include SEC filings (EDGAR database), financial data providers (e.g., Bloomberg, Refinitiv), and financial websites (e.g., Yahoo Finance, Google Finance).
• **Spreadsheet Tools:** Utilize spreadsheet software (e.g., Microsoft Excel, Google Sheets) to automate the NNWC calculation and screening process.
• **Patience and Discipline:** NNWC investing requires patience and discipline. Be prepared to hold stocks for extended periods and resist the urge to trade based on short-term market fluctuations.
• **Diversification:** Diversify your portfolio across multiple NNWC stocks to reduce risk.
• **Continuous Monitoring:** Continuously monitor your portfolio and re-evaluate your holdings as new information becomes available.
• **Understand the Business:** Don't just rely on the numbers. Take the time to understand the company's business, industry, and competitive landscape.
• **Tax Implications:** Consider the tax implications of your investment decisions.
• **Brokerage Fees:** Factor in brokerage fees when evaluating potential returns. Comparing Brokerage Services is important.
• **Risk Management:** Implement appropriate risk management strategies, such as stop-loss orders, to protect your capital.
• **Stay Updated on Technical Analysis**: Although NNWC is a fundamental strategy, understanding market trends and using technical indicators like Moving Averages or Relative Strength Index (RSI) can help with timing entries and exits.
• **Be Aware of Candlestick Patterns**: Recognizing bullish or bearish patterns can offer further insights into potential price movements.
• **Monitor Trading Volume**: Low volume can indicate illiquidity and potential price manipulation.
• **Utilize Fibonacci Retracements**: These can help identify potential support and resistance levels.
• **Analyze Bollinger Bands**: These can indicate volatility and potential overbought/oversold conditions.
• **Keep an eye on MACD (Moving Average Convergence Divergence)**: This can signal potential trend changes.
• **Track Stochastic Oscillator**: This can identify potential overbought/oversold conditions.
• **Study Elliott Wave Theory**: Understanding wave patterns can help predict market movements.
• **Observe Support and Resistance Levels**: Identifying key levels can inform entry and exit points.
• **Consider Chart Patterns**: Recognizing patterns like head and shoulders or double tops/bottoms can provide trading signals.
• **Evaluate Trend Lines**: Identifying and following trend lines can help determine the direction of the market.
• **Understand Gap Analysis**: Gaps in price can indicate significant market sentiment.
• **Monitor Average True Range (ATR)**: This measures volatility and can help manage risk.
• **Use On Balance Volume (OBV)**: This can confirm trends and identify potential reversals.
• **Study Ichimoku Cloud**: This provides a comprehensive view of support, resistance, and momentum.
• **Track Accumulation/Distribution Line**: This can indicate whether a stock is being bought or sold by informed investors.
• **Analyze Volume Weighted Average Price (VWAP)**: This can help identify potential entry and exit points.
• **Be aware of Divergence**: Identifying divergence between price and indicators can signal potential trend changes.
• **Understand Correlation**: Analyzing the correlation between different assets can help diversify your portfolio.
• **Monitor Inflation Rates**: Inflation can impact company earnings and valuations.
• **Watch Interest Rate Changes**: Interest rate changes can affect borrowing costs and investment returns.
