The most powerful investing lessons I've ever learned are counter-intuitive.

That’s logical - if they were intuitive, I would do them naturally.

Here are 7 counter-intuitive investing lessons I had to learn the hard way:
1: Don’t haggle over pennies

My instinct is to pay the lowest price possible when I buy.

If a stock is trading at $21, I used to set a limit order for $20.50, trying to squeeze out every last penny of value.
Problem 1 was my orders didn’t fill. I had to try again often at a higher price.

Problem 2 was that haggling caused me to NOT buy a few great stocks because I anchored to the lower price.

Some of those great stocks took off without me. Image
It's counter-intuitive to not haggle over pennies.

But think of it this way:

If a stock goes from $20 -> $100, does it matter if you got in at $19.56 or $21.25? Image
2: Look for stocks that have already beaten the market.

If you study Buffett & Graham (like I did), you train yourself to look for cheap business.

I used to scan the “all-time low” list for ideas and avoided stocks trading at 52-week highs.
I’ve learned the hard way that winning stocks tend to keep on winning.

And losing stocks tend to keep on losing.

I now see it as a GREAT sign if a company has already beaten the market.

My favorite investing thesis has become: Image
After all, if you bought:

$AMZN in 2010
$AAPL in 2012
$NFLX in 2015
$TSLA in 2017

You’ve done incredibly well, even though those stocks were ALREADY up huge.
3: Watch the business, not the stock.

My instinct is to focus on the share price.

What is happening with the stock TODAY?

Pull up any stock’s data; what’s the first thing you see? Price!

What does the media report on? Price!
I've learned the hard way that short-term movements are random. They are unpredictable and often do not correlate to the business at all.

But, in the long-term, they are 100% correlated to the business. Image
It's counter-intuitive to ignore the stock price and focus on the business results, but that's the smarter way to invest.
4: The P/E ratio IS NOT universally applicable.

When I first learned about the P/E ratio, it just made sense.

It became the yardstick I used to judge every company’s valuation.
Yet, the P/E ratio has been a false indicator SO. MANY. TIMES.

It told me to avoid "expensive" stocks - that then crushed the market.

It told me to buy "cheap" stocks -- that then fell hard. Image
It's counter-intuitive that you can't use the P/E ratio on all stocks at all times.

I learned the hard way you need to know WHEN the P/E ratio is useful and when it’s not. Image
5: If you’re right 50% of the time, you’re system is WORKING.

My instinct was that 50% of stocks beat the market and 50% lose to it.

The same odds as a coin flip.

Therefore, an accuracy rate ~60% was needed to outperform.
A JP Morgan study from 1980-2014 changed my mind. It showed:

-> ~36% of stocks beat the market
-> ~10% of stocks accounted for nearly ALL the index's gains

This means that the odds of picking a winner are not a coin flip; they are a dice roll! Image
It's counter-intuitive that you can outperform the market when less than 50% of your stocks outperform.

But that's how the stock market works!
6: Add at lower VALUATIONS, not just lower PRICES.

My instinct was to double down on my losers.

If I liked a stock at $20, and the price is now $10, I should buy more, right?

Well, not necessarily…
The question to ask: is the BUSINESS stronger or weaker?

If the stock is up 10%, but earnings are up 20%, the stock could be a BETTER buy, even though the price is higher.

Unfortunately, the inverse is also true. Image
It's counter-intuitive that a stock price can be higher and a better investment at the same time.

I've learned the hard way to buy at better valuations, not just better prices.
7: Low Valuation ≠ Undervalued & High Valuation ≠ Overvalued

Morgan Housel wrote an eye-opening article in 2013.

He looked at the Dow stocks in 1995 and asked:

What P/E ratio did you need to pay back then to earn an 8% return?
This table summarizes the results:

The findings:

Many high-valuation stocks were UNDERVALUED.

Many low-valuation stocks were OVERVALUED. Image
It's counter-intuitive that a high-valuation stock can be better than a low-valuation one.

I've learned the hard way that high-quality businesses deserve to trade at a premium and low-quality businesses deserve to trade at a discount.
Many of these counter-intuitive lessons have one word in common:

Valuation.

Which is the trickiest part of stock investing!

I'm hosting a free webinar tomorow (7/19) that will help to demystify valuation:

To summarize:

1: Don’t haggle
2: Find stocks that are already market beaters
3: Watch the business, not the stock
4: Know when to use P/E ratio
5: Know the odds
6: Add at better value points, not better prices
7: High Valuation ≠ Overvalued & Low Valuation ≠ Undervalued

Another major difference.

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

Capitalism is brutal.

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)
▪️Expenditures (Costs / Expenses)
▪️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
