Why Amazon.com (Nasdaq: AMZN) Is Today's Best Pre-Earnings Trade

Amazon.com Inc.'s (Nasdaq: AMZN) upcoming earnings report on Thursday takes on a whole new significance in light of Wal-Mart Stores Inc.'s (NYSE: WMT) bombshell announcement that it's expecting a 6% to 12% earnings cut over the next two years.

Expectations are high this close to earnings, and the volatility I'm seeing with AMZN shares tells me traders are afraid Amazon might not deliver this week.

But I'm going to show you a cool chart - one that less than 1% of all traders and investors ever see - that reveals a juicy opportunity for us in this atmosphere of nervous anticipation.

So let's keep our cool and make some money as Amazon's "moment of truth" gets closer...

The Stock Chart Everyone Wants to See

The stock chart you see in front of you is a special chart. This chart shows Amazon's share price along with the result of the last earnings report back in late July, but it shows something else as well...

AMZN

The blue line you see moving up and down - that's not a moving average or any popular technical indicator. That line is the implied volatility for the near-money options that trade on Amazon, and it's really rare, valuable data.

Here's what it means for us.

I like to call this line the "fear factor" line. As the line goes down, there is less fear of the day-to-day movement of the stock. As the line goes up, so does the uncertainty about the future and, of course, options prices.

For Amazon, the option's implied volatility trades in a range of 20 to 80. If the line goes from 20 to 80, it basically means that an option's time value theoretically increases by a factor of four.

Now let's create an outlook for this week's Amazon earnings. Even though most people know that Amazon has met or beat expectations in three of the last four quarters, I am more interested in what the stock did before and after earnings...

AMZN

So in the week leading up to earnings the last four times Amazon reported, we saw an average share-price move of 4.18%, mainly to the upside. This was before earnings, but not through earnings.

AMZN

Now, in the days following earnings, AMZN stock moved an average of 15.31%, with three out of the four quarters moving higher by double digits.

Put these two spreadsheets together and you are talking an average 20% move to the upside on the stock in three of the last four quarters.

AMZN: Here's How We'll Play It

First, it makes sense to actually look at the near options expiring this week. This gives us a gauge of how far the stock could go just after the report.

AMZN

As of earlier this week, AMZN October 15 2015 $570 (AMZN151015C00570000) calls and AMZN October 15 2015 $570 (AMZN151015P00570000) puts expiring this week are trading at around $50 when combining the costs. That's what I like to do to get a read on where this stock might go after earnings. We want to see the range right around $50.

Now we have to consider the likelihood that Amazon stock will head higher after earnings. I think the shares have a 75% chance of heading higher against a 25% chance of heading lower.

But this does not - repeat, not - mean we should go for a straddle...

First, the straddle above would cost $5,000 per contract to buy, which already violates a major rule for me. Next, buying a straddle and holding it through earnings will stack the odds against you.

Buying a straight call option puts you a bit further into probability's favor, but only just - and before the probability traders out there start writing angry comments, remember there are two kinds of probability that concern us here:

Statistical probability - with options, when you bet on the long shot, you could win more, but of course the odds of winning becomes far less. Don't let the probability calculators fool you into thinking that naked options selling is the only way to trade; it's just a guide and should be treated as such.

Remember Long Term Capital Management? They used to be a big name, just like Tyrannosaurus Rex and the dodo. Well, LTCM's Myron Scholes helped create the Black-Scholes Option Pricing Model that most calculators are based on - before the company went bankrupt trading on the theory and almost scuttled the American economy back in the 1990s.

We are banking on historical probability for this trade. While not perfect, it's the lifeblood of a rules-based trader. Follow the pattern. And the pattern here suggests we do something bullish.

Here again it's the loophole trade that offers the least risk, most reward, and best probability for option buyers.

Buying short-term loophole trades that expire this week makes sense to those who believe AMZN could pop $50 by Friday. Here are a few examples of where some spreads are right now using AMZN October Week 4 options:

AMZN

AMZN October 23 2015 $575 (AMZN151023C00575000) calls mid quote at $18.05

AMZN October 23 2015 $600 (AMZN151023C00600000) calls mid quote at $9.02

AMZN October 23 2015 $615 (AMZN151023C00615000) calls mid quote $5.47

AMZN October 23 2015 $625 (AMZN151023C00625000) calls mid quote at $3.87

Prices as of Tuesday, October 20 3:30PM EDT

Now, don't let the colors scare you. I did this to point out three different examples that suit the risk tolerance of most investors.

The green highlighted option has the highest risk but the lowest breakeven point at Friday's close.

The yellow in the middle has lower risk and higher reward, but a higher breakeven.

And the red highlighted option offers the lowest risk and highest reward. Nothing is guaranteed, of course, but any one of these strategies will get you paid handsomely when Amazon.com's expected post-earnings breakout takes shape.
