Why Did The Stock Market Crash?

Last Wednesday, I warned during my live show that the market could crash soon. 

And it did:

Nasdaq September Market Crash Chart

The next day the NASDAQ lost more than 5% – and for the next few days it kept moving lower.

And not to brag, but I pretty much nailed my prediction:

I said the S&P would correct to 3,400 and then bounce back. Well, I was off by a few points. It went down to 3,330 and then bounced back. Close enough 🙂

So why did the stock market just have a bit of a flash crash? 

And will they keep crashing, or is the worst over now?

In order to answer the question “why are the markets crashing,” let’s back off for a moment and discuss why stocks exist in the first place.

At some point, a company may need to raise capital, and they don’t necessarily want to borrow it from the bank. So they sell parts of the company to investors, and these are shares.

Let’s take a look at a company like Apple AAPL:

Outstanding AAPL Stock Shares

They have issued 17.1 BILLION shares.

Now let’s compare this to another company that has been incredibly popular this year, Zoom Communications (ZM). They have issued 194.76 Million shares. As you can see, that’s much less.

Outstanding ZM Stock Shares

EPS And A Market Crash?

So in order to compare these 2 companies, smart people (way smarter than me) came up with the idea of creating a metric, the EPS, or Earnings Per Share.

This metric tells you how much a company earns per ONE share of stock that they issue. So for AAPL that’s $3.30 and for ZOOM that’s $0.78.

As you can see, AAPL is much more profitable per share that they have issued compared to ZM. No surprise.

Now… what does THIS all have to do with the market crashing? Bear with me… you’ll see in a moment.

So now you know about the “EPS” – the Earnings Per Share. The next key metric that you need to know is the “P/E” ratio.

PE Ratio or Price Per Earnings

The PE ratio is the “price per earning,” so you take the stock price and divide it by the earnings per share (the profit) of the company. This PE ratio tells you how much overvalued or undervalued a company is.

Let’s take a look at the PE values of AAPL and ZM.

For AAPL, the PE ratio is 35.79. So this means that the stock is trading at 35x the profits. For ZM, it is a whopping 490!!!  The stock price is 490 times the earnings! That’s crazy!

So let’s see what’s normal.

Here’s the PE ratio of the S&P 500 companies.

S&P 50 PE Ratio and Market Crash


Right now, it’s 29.24, so almost 30. Apple’s PE ratio is 35, so it’s close to the average of the S&P 500 companies.

But AAPL is a tech stock, and we know that the NASDAQ is the “tech index.” So let’s take a look at the PE Ratio of the NASDAQ.

Nasdaq PE Ratio

It’s 26.52 right now.

Wait, what???

I thought everybody was saying that tech stocks are overvalued???

Well, it seems they are in line with the S&P 500, and it’s also in line with its historic averages.

So why is everybody saying that stocks are overvalued right now? And why did the market crash?

Well, there’s a simple explanation. Let’s dive a little bit deeper into the NASDAQ.

There are 100 companies in the NASDAQ Index, and here’s how they are weighted.

These 7 Companies Can Cause A Crash

As you can see, the Top 7 companies make 50% of the weight of the index.
We already looked at Apple and know that their P/E ratio is at 35 right now, and that’s AFTER the correction. So it’s still higher than the average of 26.52 but not too crazy.

Let’s take a look at the others PE Ratio:

2.) AMZN: 126.

3.) MSFT: 37

4.) FB: 33

5.) GOOGL: 34

6.) GOOG: 35

7.) TSLA: 907

So as you can see, these 7 companies currently account for 50% of the NASDAQ, and are all trading higher than the average, with AMZN and TSLA being crazily overvalued.

And simply put, that’s why the market crashed.

At some point, the big hedge fund guys realized, “Oh man, we have some crazy stocks here in our portfolio! They are overvalued!” And so the big guys are taking some profits off the table and SELLING these heavily overvalued companies.

And if they “only” sell shares of these 7 companies, then it drags the whole Nasdaq down.

So will the market continue to move lower?

Earlier this year, the NASDAQ lost 30%. Can this happen again, or is over after this 10% drop? Well, we had this pandemic, and NOBODY knew how it would affect our economy. So the big guys did what they usually do when there’s uncertainty: SELL and sit on a pile of cash, like Warren Buffet.

But you’re not earning any money on cash. At some point, you need to invest the money again in the market.

And once we had a better idea of how the virus affected our economy, the big guys started buying again.

So if we look at this “flash crash” in September 2020, here’s what happened: The big guys – a.k.a SMART MONEY – noticed that some of the stocks that they purchased went up too much, and they sold them to take profits.

But they can’t sit on the cash for long. They need to earn money, so they invest it again after values are back to normal. And that’s what we are seeing today: It’s called “buying the dip.”

Summary: Why Did The Markets Crash?

You should now be familiar with both EPS (Earnings Per Share) and the PE Ratio (Price Per Earnings).

And you know that the big guys – the smart money – they’re keeping a close eye on these numbers.

If they get too high, then they SELL some stocks and realize a profit, and they buy companies with a lower PE ratio.

And THAT is why the markets crashed for a few days – and why they are bouncing back right now.

  1. Great article Markus, thank you for showing us how to understand the market, you explanation is simple and clear.
    Thank you for the education sir!

  2. I like the video, but all that you say was true before the crashundefinedcorrection. What caused the timing of it? I think it was Elon Musk trashing the people who'd bought his stock before the split. For anyone buying one or more shares before the split in the hope of selling a few for a profit and holding on to one or two, his announcement that he was going to sell $5 billion of TSLA stock destroyed them! He used to try to kill the shorts. Now he killed his shareholders. I think that was what pushed the first domino over and started the correction.

    1. No one can say the exact reason why it crashes. To be honest, the market does not care about those things. 🙂 Corrections are bound to happen.
