Here's everything you need to know: Image
They confused me until I discovered an easy way to distinguish them:

Some stocks are STRONG BUYS when they fall

Other stocks are SELLS when they fall

How can you tell the difference?

Watch for these 5 financial yellow flags: Image
1) GOODWILL WRITEDOWN

This represents the premium a company pays for an acquisition above its fair market value.

If there’s a major goodwill write-down on the Income Statement, it means management has wasted a TON of capital. Image
2) GROSS MARGIN DECLINING

1: The competition is forcing me to lower prices
2: Demand is weak
3: My suppliers are raising prices

Either way, it can be a thesis-busting development Image

If you invest, you MUST know how to identify a moat.

Here are 9 financial “rules of thumb” that Warren Buffett uses to tell if a company has one: Image
1: Gross Margin

Found: Income Statement

Formula: Gross Profit / Revenue

Moat: Consistently above 40%

No Moat: Under 40% & volatile Image
Buffett’s logic:

A consistently high gross margin signals that the company isn’t competing exclusively on price.

A high gross margin also provides ample gross profit to pay expenses and leaves money for shareholders.

How to analyze an income statement in less than 2 minutes: Image
The income sheet is one of the three major financial statements.

It shows a company’s:
▪️Revenue (Sales)

▪️Net Income (Earnings, Profits)

Over a period of time. Image
Management teams have leeway in categorizing their income statement.

This means that not all income statements look the same.

Here is a typical layout and the meaning of the most commonly used terms: Image
