Probably the most impactful teacher I've had so far. He took my fundamental analysis to a whole new level. I'm aware these notes aren't "wisdom", but they're concepts and mental models I use till this day!


Operating Leverage + DOL

  • Is the relationship between fixed and variable costs.

  • Airline industry tends to have high OL

    • Fixed costs are higher than Variable costs

    • Therefore it has a high OL. This means profits increase higher as the ticket sales increase because the fixed costs are already paid

  • DOL = Degree of Operating Leverage

    • Measures how well a company generates profit using its fixed costs

      • (Sales - VC) / Profit

    • If DOL is 1.6 and sales increase by 10%, the profits will increase by 16%.

  • What leads to operating leverage

    • Margin expansion

    • Asset turns improving 

    • Signs in con calls and interviews

    • Triggers linked to Variant Perception and Return Ratios playing out

  • Triggers

    • Capacity utilization/expansion

    • Revenue mix transition

    • Acquisition Synergy

  • How to use

    • In asset heavy sectors (hospitals, hotels, chemicals), track capex and assets

    • Look out for peak PE, margins, operating leverage

    • Type in “Margins will expand” or “Operating Leverage” into Screener

  • In some companies, operating leverage can never kick in because the company is required to constantly do capex due to consumer demand 


Price / Earnings

  • what decides the perception

    • when there are industry tailwinds pe ratio is rerated

    • bear vs bull market

    • higher interest rates lower pe ratio

    • company gaining market share will have higher pe ratio

    • higher earnings growth means higher perception meaning higher pe ratio

    • volatile business model means lower PE

  • What decides your return

    • entry price = entry pe * EPS

    • holding journey = pe * EPS growth

    • exit price = exit pe * EPS

    • buying a stock with pe of 60+ exposes to derating

  • How PE ratio can fool you

    • Low ratio

      • earnings are at cyclical peak

      • sitting on top of operating leverage

      • company is in dying industry or has stopped growing

    • high ratio

      • one off earnings

    • low pe example, aster DM concluding GCC business

    • high pe example, yasho industries capex

    • Peter lynch said “in a cyclical business sell low pe and buy high pe”

      • when it is high then earnings is destroyed

      • better to look at price to book and look at the trends

  • PE forecasting

    • forecast the earnings growth rate (can be from company guidance)

    • divide by market cap today to find forward PE

    • can derive base/bull/bear case by multiplying the projected earnings by certain PE to figure out the new market cap and see how much growth can be there

  • When to use specific ratios

    • PE - To be used for companies with no one off in earnings and linear to stable margins. Eg:- Can be used in IT industry.

    • EV/EBITDA - Asset heavy industries like hospitals, hotels

    • price to sales - to be used along with margin trajectory

    • price to cash flow - To be used in companies or industries where depreciation is high, and accounting PAT looks depressed. Shows real cash earnings of business in most cases.

    • price to book - most important use is in banking industry

    • mcap to order book - To be used in B2G businesses, contractors, Defence companies. Order book shows future growth potential.


ROE, ROA, ROCE

  • ROA 

    • Indicator of how well a company uses its assets in terms of profitability 

    • Gives investor idea of how efficient company management is at using assets to generate earnings

    • Net Profits / Total Assets

    • Dupont of ROA

      • Net profit margin * Asset turnover

      • Asset turnover = Sales / Total Assets

  • ROE

    • Measures company’s profitability in relation to shareholder equity 

    • Good rule of thumb is to target ROE equal to or just above average of the peer group

    • Net Profits / Average equity 

    • Companies with huge debt can fool you to show high ROE because it artificially reduces equity 

    • Dupont of ROE

      • Net profit margin * Asset turnover * Financial Leverage

      • Financial Leverage = Assets / Equity (per $ of equity, how many assets are being held) 

      • ROE is good if it comes from first 2, but not good if comes from financial leverage

  • ROCE 

    • Assess company profitability in relation to capital efficiency

    • Understand how well a company is generating profit from its capital as it is put to use 

    • Hygiene of ROCE is reflected much better in balance sheet than it is in income statement

    • EBIT (Operating Profit) / Capital Employed

    • Dupont of ROCE

      • EBIT margins * Capital employed turnover

      • Capital employed turnover = Sales / Capital employed

      • Capital employed formulas

        • Debt + equity - cash 

        • Gross fixed assets

      • If EBIT margins is good then it shows demand side advantage

      • If CE turnover is good then it is supply side advantage


Finding Fraudulent Managements

  • Reliance capital broke into nippon which was bought by a japanese MNC. today, reliance capital has mcap of 300 cr but nippon has over 40,000

  • Learn from past

    • Use GPT to ask if there were any SEBI/Accounting issues with the company in the past

  • Resignation of key management personnel

    • Search up resignation in Screener Announcements

    • Specifically CFO is important as they’re responsible for financial statements

  • Promoter shareholding “skin in the game”

    • Hindustan Oil Exploration company is 98% public + 1.8% FII

    • Had many resignations in KMP

  • Large number of Related Party Transactions

  • Complicated corporate structure

  • Companies that misguide investors

    • Hear the past 3 years concalls

    • Ctrl + F “growth” and “guidance”

    • And see what has happened

  • Overly promotional CEO

    • Frequent TV interviews, PR stunts glorifying the prompts

  • Regular promoter selling

    • Stock is at all time high yet there is no history of execution

  • Management profile and background

  • Politically exposed promoters 


Shareholding Pattern

  • 4 types of shareholders

    • FII (foreign)

    • DII (domestic)

    • Public (retail)

    • Promoters

  • Study showed that when there were 10% increase in retail investors with less than 1L investment, only 10% of the stocks went up rest were negative

  • Must look at shareholding pattern looking at FII going up and retail not going up as fast


Working Capital

  • Activity Ratios: type of financial metric that shows how efficiently a company is leveraging the assets on its balance sheet to generate revenues and cash 

    • Receivables: how efficient business is in collecting this 

    • Inventory: Inventory buildup

    • Payables: If bought inventory on credit

    • Assets: how efficiently it is used to generate revenues and cash

  • Can be used to compare two different business within the same industry or to monitor a companies fiscal health over time 

  • Inventory turnover ratio

    • Rate which company sells and replaces stock of goods

    • COGS / Average inventory

    • Sales / Average inventory

  • Receivable Turnover

    • Quantify a company’s effectiveness in collecting its accounts receivable or the money owned by customers or clients

    • Sales / Average Receivables 

  • Payable Turnover

    • Rate at which a company pays off its suppliers

    • How efficient a company is at paying its suppliers and short-term debts

    • COGS / Average Payables

  • Working capital turnover

    • How efficiently a company is using its working capital to support sales and growth

    • Relationship between the funds used to finance operations and the revenue generated to continue operations and turn a profit 

    • Sales / Average working capital

      • Working capital = Current assets - Current liabilities

      • Net working capital = Trade receivables + inventory - payables

        • AKA cash conversion cycle 

      • Gross working capital = Trade receivables + inventory

  • Working capital

    • Definition

    • If wc falls, balance sheet lightens up 

      • Debt falls

      • Capital employed falls

      • ROCE increases

      • FCF increases


Random Bits + Mental Models

  • Industry capital cycle

    • Business investment declines, industry consultation, firms exit: investors pessimistic

    • Improving supply side causes returns to rise above cost of capital, share price rises 

    • New entrants attracted by prospect of high returns, investors optimistic

    • Rising competition causes returns to fall below cost of capital, share price underperforms. 

  • Mean reversion 

    • Asset price volatility and historical returns eventually revert to the long term average of the entire dataset

    • How it can be used

      • Always look at the long term margins of companies

      • If a company starts earnings super normal margins without any change in product mix

      • Always be careful as there is a chance that the company is over earning

      • Peak valuation + peak earnings + peak margins all 3 lead to zone of danger in investing

    • “Only when the tide goes out do you discover who’s been swimming naked” - Warren Buffet

  • When to sell 

    • Volatility STOP

    • ATR 

    • 2x, 1.5x for overvalued stocks

  • PE ratio stops working when company is sitting on top of operating leverage

  • Price to book value

    • Book value is the net difference between total assets and total liabilities. 

      • Total value of company asset that shareholders would receive if the company were to be liquidated

    • Why banks use P / BV

      • Macroeconomic conditions such as inflation, interest rate etc are the same for most banks

      • What differentiates is how efficiently the funds or assets are used and how best the spreads are managed 

      • normally  cost of funds and yields are around the same levels for most banks so the P / BV is determined by how well they enhance the spreads and how well they contain their NPAs

        • NPA = Non performing asset

  • Over earning - company earning more than average due to some shortage or one off order

    • Leads to creation of massive expectations and a large base size

  • Buffet on projecting cash flow

    • We first have to decide whether we can sensibly estimate an earnings range for 5 years out. 

    • If answer is yes, we will buy the stock if it sells at a reasonable price in relation to the bottom boundary of our estimate

  • ADX - Average direction Index

    • Trend following indicator

    • Above 25 = Positive uptrend

    • 40-60 = Super trend

  • VSTOP - Volatility Stop

    • Meant for exists

    • Volatility increases when dumping occurs
