Invest Like a Guru

How to generate higher returns at reduced risk with value investing. From surviving the 2000 fiber-optics crash to synthesizing the core frameworks of Peter Lynch, Warren Buffett, Donald Yacktman, and Howard Marks.

The 5 Golden Rules (Epilogue)

Dr. Tian's Synthesis

1 Avoid Permanent Loss: Buying poorly performing companies risks permanent loss of capital, even when the price looks cheap.
2 Define Good Companies: Consistent profitability with double-digit operating margins, double-digit ROIC, and double-digit growth.
3 Fair Prices: Buy only good companies and buy them at reasonable prices (ride the "value escalator").
4 Beware of Value Traps: Once a company loses its moat and margins shrink, cheap asset multiples will not save you.
5 Don't Forget Cycles: Track corporate profit margins, Total Market Cap / GDP, Shiller P/E, and insider buy/sell ratios.

Introduction • The Bloodbath (2000–2002)

Figure I.1: Price Chart of Corning & The Fiber Optics Crash

In January 2000, working as a fiber-optics physicist in Texas, Dr. Tian bought Corning at ~$40/share (split-adjusted). It nearly tripled to $110 by autumn 2000 before collapsing below $2 in late 2002 as 97% of laid optical fiber remained "dark" and customers WorldCom and Global Crossing went bankrupt. He sold in Q4 2002 at a >90% loss—right at the exact bottom!

97% Dark Fiber

Innovations squeezed terabytes into a single fiber while telecoms overbuilt capacity across oceans.

Oplink's Survival

Lost money 9 of 10 years (2000–2009), dropping from $250 to $4.50 (with >$8 net cash!), yet survived because it had no debt.

Sir Isaac Newton (1720)

Tripled his South Sea stock, sold out, then went all-in at 3x his exit price—losing £20,000 (his life savings).

John Kenneth Galbraith & Market Psychology

4 Recurring Types of Bubble Participants

Click each participant archetype to inspect how they get trapped during market euphoria:

1. The Average Folks Newton & Early Charlie Tian

Excited about a revolutionary new idea and relatively new to the market. Seeing friends and neighbors get rich, they jump in without inspecting balance sheets or earnings.

2. The "Smart" Ones Greater Fool Timers

Recognize that valuations are unsustainable, yet believe they can ride the wave all the way to the peak and exit right before everyone else. ("Please, God, Just One More Bubble.")

3. The Short Sellers George Soros (Early 1999)

Recognize stocks are overpriced and short them. As Keynes warned, "Markets can remain irrational a lot longer than you and I can remain solvent." Soros lost 20% by mid-1999 betting against Internet stocks and was forced to cover.

4. The Forced Buyers Soros (Late 1999–2000)

Professional fund managers pressured by clients to deliver short-term gains. Soros hired a manager to buy Internet stocks and short old-economy stocks—finishing 1999 up +35%, only to get crushed when the bubble burst months later.

Who Were the True Gurus During the 1999 Bubble?

Those who refused to participate despite severe career pain: Warren Buffett (mocked by Barron's "What's Wrong, Warren?"), Julian Robertson (forced to close Tiger Management just as the bubble burst), Donald Yacktman (lost >90% of fund assets to redemptions and fought a board proxy battle), and Steven Romick (85% redeemed at FPA Crescent).

Why "Cigar-Butt" Deep Value Loses to the Value Escalator

"Time is the friend of the wonderful business, the enemy of the mediocre." — Warren Buffett (1989 Letter)

Interactive Simulation: Margin of Safety & Intrinsic Value Trajectory

Compare Figures 2.1, 2.2, and 3.1 + Chapter 3's 10-Year Valuation Math Proof (p. 82)

Figure 3.1 — Good Business ("Riding an Escalator"): Intrinsic value compounds steadily year after year. Even if you pay a fair price (or slightly overpay by 20%, which reduces 10-year annualized return by just 1.8%/yr), time is on your side, there is no rush to sell, and capital gains taxes are deferred!

Chapter 2 • Ben Graham's Net-Net Bargains

4 Liquidation Valuation Formulas & Cohort Decay

From least conservative to most conservative (July 19, 2016 examples):

1. Tangible Book Value (TBV)

(Total Assets − Liabilities − Preferred − Intangibles) / Shares

2. Net Current Asset Value (NCAV)

(Current Assets − Total Liabilities − Preferred) / Shares

3. Net-Net Working Capital (NNWC)

(Cash + 0.75×AR + 0.5×Inventory − Total Liab − Pref) / Shares

4. Net Cash Per Share

(Cash & Short-Term Inv − Total Liab − Preferred) / Shares

July 19, 2016 Stock	TBV	NCAV	NNWC	Net Cash	Price
Emerson Radio	$1.99	$1.93	$1.75	$1.75	$0.68
Adverum Biotech	$8.92	$8.78	$8.73	$8.70	$3.07
Carbylan Therap.	$1.64	$1.63	$1.59	$1.59	$0.59

Why Deep Value Failed After 2010:

• Dec 2008 Net-Net Portfolio (S&P=872): Averaged +257.6% by July 2011 vs. +48.5% for S&P 500 (17 of 20 positive; ValueVision Media +2,759%).
• Oct 2009 Net-Net Portfolio (S&P=1020): Up +50% in Year 1, then eroded: −17% (Yr 2), −2% (Yr 3), −28% (Yr 4) as value drained!
• Apr 2011 Net-Net Portfolio (S&P=1332): Lost −10%, −20%, +11%, and −30% while the S&P 500 marched higher. Plus Berkshire's 1985 textile machinery ($13M original cost, $866k book value) liquidated for just $163,122 gross (net less than zero!).

Chapter 3 Empirical Research (2006–2015 Full Market Cycle)

The 3 Fundamental Questions: Studying 3,577 U.S. Stocks & 454 S&P 500 Stocks

Question 1: Is the company consistently profitable? Out of 3,577 continuously traded U.S. companies (2006–2015), the 1,045 companies (29%) profitable all 10 years averaged +8.5%/yr with only a 6% chance of loss (and for the 291 S&P 500 companies profitable all 10 years: +11.1%/yr with just 2% losers!). Companies profitable ≤6 years had negative average returns.

Two-Stage DCF, Reverse DCF & Comprehensive Valuation Multiples

Even a wonderful company delivers subpar returns if you overpay: Wal-Mart at P/E 60 in 1999 took 12 years to break even despite quadrupling earnings; Coca-Cola at P/E 95 in mid-1998 ($43 split-adjusted) was still below $43 18 years later!

See's Candy (1972–1999) Discounted Pretax Earnings

Discount Rate:

Buffett paid $25 million net of excess cash ($35M minus $10M cash) for See's Candy in 1972 when it earned $4.2M pretax. By 1999 it earned $74M/yr ($859M cumulative pretax from 1972–1999), and another $1B+ from 2000–2014! Even at a steep 25% discount rate, its 1972–1999 pretax cash flows were worth $55.1M in 1972 dollars (and $153M at a 12% discount rate).

Chapter 9 • Comparing 6 Valuation Methods (Sept 2016 Data)

Household Names & Berkshire Acquisition Multiples

Key Takeaway (p. 189): Book value works for banks (Wells Fargo at $44 vs. $35 BV). Graham Number and EPV ignore growth and severely underestimate asset-light compounders. Only Apple ($112 price vs. $244 DCF) offered a 30%–40% margin of safety in Sept 2016!

Chapter 9 • Rate of Return Approach (p. 191–193)

Earnings Yield & Yacktman's Forward Rate of Return

Forward Rate of Return = Normalized FCF Yield + Growth Rate

U.S. Retailer (Sept 2016)	Earnings Yield	EBIT / EV	Forward Return
Costco Wholesale	3.5%	5.6%	11.5%
Dollar General ★	6.1%	10.4%	15.3%
Dollar Tree Inc.	3.9%	6.0%	19.1%
Target Corp.	7.8%	10.2%	6.0%
Wal-Mart Stores	6.5%	9.0%	7.8%

Which Multiple Fits Which Industry? (Ch 9 Guide)

• Peter Lynch Earnings Line (15x EPS or Historical Median P/E): Best for steady stalwarts (General Dynamics, CVS Health at 18.6x median P/E).
• Price/Sales (P/S) Bands: Best for cyclicals whose margins revert to the mean (Southwest Airlines LUV) and consistent revenue compounders (J&J at ~3.5x P/S, Amazon at ~2.25x P/S).
• Price/Book (P/B) Bands: Best for banks & insurers with mark-to-market assets (Berkshire Hathaway, Wells Fargo). Useless for asset-light buyback machines with negative equity (Moody's, AutoZone).
• Shiller P/E & P/B: Best for commodity producers (ExxonMobil, Chevron, PetroChina) where regular P/E spikes to 150x or turns negative at cycle bottoms!

Chapter 7 • "Dead Companies Walking"

8 Business Behaviors to Avoid at Any Price

1. Hot Product, Bright Future: Solar bubble (Suntech Power $12B → bankrupt; SunEdison bankrupt; First Solar & SunPower −80%; SolarCity merged into Tesla).

2. Fad Product Everyone Buys: Crocs ($6B cap → −80%) and teen retailer Aeropostale ($3B cap → −99% & bankruptcy).

3. Peak of the Cycle: Low P/E at peak earnings traps buyers in autos, airlines, and commodities.

4. Growing Too Fast: Krispy Kreme (early 2000s), Starbucks (closed 900+ stores in mid-2000s), Tesla cash burn.

5. Aggressive Serial Acquirer: Valeant Pharmaceuticals under CEO Michael Pearson (debt exploded from $380M to $30B; stock crashed −85%).

6. Too Competitive: Department stores & retail (Vornado, K-Mart, Circuit City, Sports Authority, Macy's).

7. Chasing Market Share at All Costs: Subprime banks, Texas Select insurance (bankrupt 2006) vs. Buffett's disciplined National Indemnity.

8. Regulatory Shifts & Aging Tech: For-profit colleges; newspapers, Kodak, Blockbuster, and BlackBerry.

The 4 Stages of Value Trap Decline (Weight Watchers & BlackBerry)

Even legendary value firms Primecap and Fairfax Financial got trapped buying BlackBerry at $17 in 2012 (down from $150 in 2008), watching revenue fall from $8B to <$1.5B, tangible book value shrink from $12.50 to $1.72, and the stock drop to $7. Watch how Weight Watchers ($80 in 2011 → $10) progressed through all 4 stages as free mobile apps eroded its moat:

Stage 1 (2000–2006): Gross & Operating Margins Decline First. Revenue and total profit still rise, masking the loss of competitive advantage.

Early Warning

Stage 2 (2006–2012): Revenue Growth Slows; Earnings Stop Growing. Valuation multiples look "cheap" on trailing earnings.

Trap Armed

Stage 3 (2012–2013): Revenue Slows Further; Earnings Decline. Value investors pile in for "bargain" P/E multiples.

Steep Losses

Stage 4 (Since 2013): Both Revenue and Earnings Decline. Even Oprah Winfrey buying 10% in Oct 2015 couldn't change free app competition.
