Earlier this week, I read over my Apple post from last weekend and decided that just about all of the information was basically useless.

And my first thought as I started writing this post was to explain in detail what I thought was wrong with it.

But on second thought, I don't really want to write a post like that, and I'm pretty sure nobody wants to read a post like that.

What's the point?

Instead, let's take the small amount of information that actually is valuable, deconstruct it a little bit, add a few new things, and see if we can make it more useful.

**1). Total # of weeks (5 trades): 432**

*What number/percentage of those weeks resulted in either positive or negative returns?*- # of weeks with positive returns:
**248 (57.41%)** - # of weeks with negative returns:
**184 (42.59%)** - One thing to keep in mind: I'm using a minimum required rate of return of +12% annually (+0.22% weekly), so positive returns are defined as >0.22% weekly, and negative returns as <0.22% weekly.

**2). Average Weekly Trade Returns: +1.08%**

- +465.73% total return / 432 weeks = +1.08%

**3). Average Weekly S&P 500 Returns: +0.20%**

- +86.10% total return / 432 weeks = +0.20%

**4). Average Weekly Excess Returns: +0.88%**

- +1.08% - +0.20% = +0.88%

**5). Cumulative Gains %: +894.47%**

- What the huh? This is the useless information I was talking about at the start. But actually, it just needs a little bit of work.
- Our average positive weekly excess return is +894.47% / 248 =
**+3.61%** - Adjusting for the probability of a positive weekly return vs. a negative weekly return: 57.41% * +3.61% =
**+2.07%**

**6). Cumulative Losses %: -514.16%**- Average weekly excess negative return: -514.16% / 184 =
**-2.80%** - Adjusting for probabilities: 42.59% * -2.80% =
**-1.19%**

**7). Average Weekly Excess Returns: +0.88%**- +2.07% + -1.19% = +0.88%
- I could call this 4a since we're back at the results calculated in step 4 above, but I think we've found some additional information that is very useful by adding steps 5 and 6

Before we get to the Omega Ratio, let's take a quick look at risk. I evaluate the risk to a position with 3 numbers (the following numbers, without digging into the equations, are my current calculations):

- Value at Risk (VaR):
**-10.10%** - Maximum Actual/Historical Drawdown:
**-19.43%**(the week of 1.22.08) - my Volatility-Based Trailing Stop:
**-12.95%**(Apple closed Friday at $454.45, and my new stop for the coming week is $395.62, so ($454.45 - $395.62) / $454.45 = 12.95%.

In Apple's case, that would be my stop.

But for a stock with a limited history/limited data set like TripAdvisor (TRIP), which has the following set of calculations:

- Value at Risk (VaR): -
**10.71%** - Maximum Actual/Historical Drawdown:
**-6.93%**(the week of 4.1.2013) - my Volatility-Based Trailing Stop:
**-19.79%**(($80.94 - $64.92) / $80.94)

Okay, so back to the...

**8). Omega Ratio: 1.74**

- +2.07% / -1.19% (absolute value) = 1.74
- Is that good or bad? It's good, but we obviously need some context here.

So how does Apple rank?

This is my current Top 10 (by Omega Ratio):

1. TripAdvisor (TRIP): 2.74

2. LyondellBasell (LYB): 1.88

**3. Apple (AAPL): 1.74**

4. Marathon Petroleum (MPC): 1.70

5. Mastercard (MA): 1.63

6. NetFlix (NFLX): 1.63

7. Intuitive Surgical (ISRG): 1.59

8. Precision Castparts (PCP): 1.57

9. Priceline.com (PCLN): 1.52

10. Discover Financial Services (DFS): 1.51

FYI - I planned to include a table with all of the Average Weekly Positive and Negative Returns, Probabilities, and resulting Omega Ratios... but it wouldn't fit.

Alright, so if the idea was to make this information more useful, then how are we going to use it?

My first thought, with 20 weeks left in 2013, is to project, based on the numbers we've calculated above, how much a share of Apple will cost at the end of 2013.

I never do this kind of thing (until right now apparently), and I generally don't like predictions of any kind, so I'm going to call this a falsifiable hypothesis:

- The closing price Friday was $454.45, and ((1+0.0088)^20)-1) = +19.12%, so $454.45 plus an additional 19.12% =
**$541.35**.

Yes, I realize that new information will render that number useless a week from now. The irony is not lost on me. But this is still fun.

Where do you think Apple will be at the end of 2013?

Or at the end of August for that matter?
