Today's Sells

by billb 31. October 2007 17:23

I'll be selling NVDA, OTE, MW and TXT from the picks.  I'm going to hold through the fed at 2:15.  While I think there will probably be no big rally on the fed news (and maybe even some selling), I'm going to keep my personal speculation out of the process.  As usual, I'll start selling somewhere around 3:00-3:30.

I'll post tomorrow's buys late today or early tomorrow along with my option play on the picks.  I'll post the monthly results probably Thursday or Friday depending on time.

QuantLib Preliminary Review

by billb 31. October 2007 11:04

Getting back a bit more to my roots, I wanted to talk about my recent experience with QuantLib.  I'm working on a piece of software that I wanted to calculate option prices in a robust fashion.  I know RightEdge has this capability and I obviously have the source code, but I needed something a bit more heavyweight that had different pricing engines and support for binaries (exotics).  Enter, QuantLib.

QuantLib is a free/open-source library for modeling, trading, and risk management in real-life.  The library's native language is C++.  I have plenty of C++ experience, but I prefer doing my projects in C# these days.  It was nice to see that someone had written a wrapper via SWIG so that QL could be used from within C#.  The first step was to convert some of the sample applications in QL from C++ to C# using this wrapper.  The EquityOption sample was the obvious choice for my task at hand.  I was able to calculate NPV using a variety of pricing engines ranging from Black-Scholes all the way to Bjerksund-Stensland and many in between (some I'd never heard of!).  I managed to accomplish this in about 2 to 3 hours on a lazy Sunday afternoon.  So while the rest of the world was watching football, I had a nice pricing calculator coded in C#.
 
Based on the volume of classes, it's apparent very early that I'm only scratching the surface of the capabilities of this library.  I knew at some point I would have to spend some time to learn all that it could do and more of how it fit together.  This happened sooner than I expected when asking for greeks threw an exception.  Naturally, I assumed this was my mistake.  Maybe I needed to initialize something or pass in a different parameter or use a different class.  It turns out that most of the pricing engines don't seem to support partials.  A read through the QL mailing lists showed similar complaints and in the spirit of open source, the answer is to write it yourself and offer it up as a contribution.  This is typically why I avoid open source software/libraries.  If I wanted to write it myself, I would.  But you typically use libraries to save yourself time and know that the implementation details have already been run through by an expert.  It seems like I bought a car without doors and when I queried the dealer, he told me to craft the doors myself and attach them.  The bolts and hinges are already there.
 
The library obviously supports a number of instruments so I'm not sure if I just hit a roadblock that is just uncommon.  I noticed that some of the calculation engines would fall back on the BlackCalculator class.  The only problem here is that BlackCalculator was not exposed to C# via SWIG.  In fact, there were a number of missing classes in the wrappers.  This had also come up again in conversation on the mailing list, to which the answer was to convert it yourself and if you want to, become the new point guy on the C# SWIG wrappers.
 
This library has great power and amazing potential.  It's a great starting leap for someone or a company who wants to hold source to something that's probably very core to their program.  But be prepared to make a committment to understanding the shortcomings and you will need to get your hands dirty to get around them.  There are obviously some very talented individuals working on this project.  If you don't need source and don't need to understand the underpinnings, you may want to consider buying a commercial library.
 
Would love for QL experts to chime in.

Fed Rate Cut, I Don't Understand

by billb 30. October 2007 12:03

I was firmly opposed to the previous rate cut, although there were reasonably convincing arguments for a 25 bps cut.  The 50 bps cut was just unnecessary.  So now here we are again and I hear that another cut is in the making.  Why now?  Did Cramer pound on a desk somewhere and I missed it?  Something does not pass the smell test.  Apparently the economy is doing all right and inflation is in check so it only makes sense to cut rates.  [cough].  I know that all is not rosy.  The economy while expanding is definitely slowing, but this seems like part of a cycle to me.  The housing market is still the pits, but I think most of the fear and uncertainty is behind us.  Inflation is higher than most would care for, but still historically low.  The cut will murder the dollar and while it may bail out those in trouble with their mortgages, it also hurts that same group of people who have to make a decision to fuel up or pay the house note.

Maybe some of you fancy pants book learners can an enlighten me because I don't get it.

Stock Pick Week in Review, October 27

by billb 27. October 2007 13:54

We're coming up on the end of the month.  It's been one of the rockier rides lately thanks to MW and NVDA.  Even GTLS just sort of floated down all month.  The switch will be made Wednesday around the close (I usually start selling around 3:00pm).  New buys are made at the first of the month (Thursday).  I'll post the changes on Wednesday.

But for now, here's the latest numbers.

I underperformed all of the major averages this week but still squeaked out a gain for the week.  I'm still down for the month.  The only other index that is currently down for the month is the Dow (down 1.28%).

Option Attempt

I am also exploring the possibility of a put credit spread in lieu of buying one or more picks this coming month.  This will insure that there is no confusion in tallying the numbers.  While I have much experience with put credit spreads, I usually trade them on highly liquid symbols.  Another thing this will introduce is additional trades on the short option.  I may sell the short side if the price gets to within a nickel or a dime.  This makes the testing a little less cut and dried.

MSFT, Glad I Missed That Trade

by billb 26. October 2007 13:28

I have a few stocks that I watch that have been stuck in multi year ranges.  GE, MSFT, mostly lethargic big caps.  When they're at the top of their range, I like to consider shorting, when they're at the bottom, I consider going long.  This is almost always done with an option spread.  Well, I had my analysis nearly complete for MSFT and at 31.00, it was on my radar.  I looked at a bearish calendar (one of my favorite strategies for these slow moving dinosaurs) and noticed the IV was juiced which meant that earnings were near.  Sure enough, they were, so I thought I'd wait it out since a vol crush would really hurt my calendar spread.

The second thought along these lines is that MSFT may post good earnings and get a jolt to the upside.  Maybe it would hit $32 and I could get an even better price on my calendar.  The move MSFT made last night made headlines.  The gain was so big in fact, that I may consider scratching MSFT from my boring channeling stock list.

Meanwhile, the NVDA trade is going to hell.  It's still up nicely overall, but it's given a lot back over the last couple of days on some downgrades (yesterday) and some speculation that someone big knew of the impending downgrades (the day before yesterday).  We'll see what our numbers look like tomorrow.

Option Volatility in Practice

by billb 24. October 2007 10:07

I came across a post in an option trading board that I frequent.  The post refers to a recent short straddle trade on AAPL and it reads:

"Covered straddle at $16.15, I just wanted to profit from the IV drop, from 54% to 41% in NOV straddles.   Great example of knowing how volatility works. Stock gapped from 174 to 187 and the 175 straddle went from 19.30 to 16.15 when I covered at 9:41 AM. Vol crush.

People who bought the straddle expecting a big move, got the move but still lost money, purely on volatility."
 
I could not have said or demonstrated this any better myself.  Most of the option picking services that I've come across explain how to use options in a leveraged fashion to capitalize on price movement.  Rarely, bordering on never, do I see them mention volatility or the implications of volatility on their positions.  If you're considering options in any fashion, spend the time to learn about how volatility will play on your position.  If you're speculating on price alone, you're likely missing half of what's causing your option value to change.

Fox Business News Channel Review

by billb 22. October 2007 11:13

I have switched over to FBN most of the time that I'm watching financial television now (usually early in the morning and early in the evening).  They have some interesting shows and takes, but some things have to go.  The "Money for Breakfast" show features some very bright people and traders in Eric Bolling and Charles Payne.  But they have an ever so obnoxious "Jargon Alert".  Now I'm all for keeping the jargon to minimum, but I've heard the whole conversation stopped now three times to explain what a P/E ratio is.  How long will this go on?  It seems a bit excessive.  It's a business channel and you should have some very basic jargon under your belt.  I don't expect ESPN to explain the infield fly rule on each episode of Baseball Tonight.

I must admit, I have listened to the Dave Ramsey show on the radio here in town and it seems like his show on FBN is along the same lines.  I enjoy the guy in limited doses.  He is doing a very good thing teaching people some common sense, baby stepped things about money.  A bit similar to Suze Orman I suppose (although I can't stomach her).  I just wonder if the "get out of debt, quit spending more than you make" is really appropriate as an every day show and appropriate to their target audience.  It seems like a nice weekend type show when people are thinking about personal finances after concentrating on work all week.
 
I've always found a ticker at the bottom of the screen to be borderline useless, especially in this day and age.  A news crawler is all right, but stock prices that are as stale as month old bread are just a novelty at best.  Well FBN has brought a new level of uselessness by flashing up one quote at a time like a sports score.  I think I counted seven seconds for each symbol being displayed.   That would take it about an hour to display quotes for the entire S&P 500.  I know this isn't where one should get stock quotes, but I think the space could be better spent (maybe on sports scores??)
 
I remember being enamored with CNBC when I first started watching it in earnest.  Of course, the novelty wore off.  I'm certainly not enamored with FBN, but it's probably because I'm at a different point in my life.  I'll continue to give it a fair shake and I'm sure they'll make improvements as they figure out what works and what doesn't.
 
Always curious to hear other opinions.

Stock Pick Review

by billb 20. October 2007 12:35

A nice drop yesterday put a bit of a hurtin' on the bulls.  This seemed like a very healthy pull back in my opinion.  It looks like I was just a one or so late on getting my bearish position together.  Story of my life.

Here are the major index numbers for the week.

Indexes This Week  
DJIA S&P 500 Nasdaq
14093 1561 2805
13522 1500 2725
-4.05% -3.91% -2.85%

The Dow and S&P really took it on the chin this week.  I still feel this was healthy and needed to be done.  The picks did pretty well relatively speaking, although MW continued it's free fall.  It's now down almost 22% from the price I picked it up from.  Again, the power of diversification allowed me to beat the S&P and DJIA this week.

Share Buyback, Not a Given

by billb 19. October 2007 12:18
You hear it all of the time, companies that buy back shares are destined to outperform.  I read this "matter of fact" statement again recently when Lenny Dykstra, advocate of buying deep in the money calls instead of shares, mentioned that he's looking at Texas Instruments for DITM call play.  One of the reasons stated is that they're buying back shares.  This is mentioned in a way as if it is a given that the stock will rise while his long options are good.  So now you're making two assumptions that aren't necessarily true.  First, that deep in the money calls are the best strategy for the play and that companies that buy back shares are giving you some sort of advantage to the upside.  Lenny Dykstra has a hammer in his toolkit and everything is a nail.
 
Fortunately for us, we have a way to measure such a thing.  The PowerShares Buyback Achievers Portfolio (PKW) buys U.S. companies that trade on a U.S. exchange and must have repurchased at least 5% or more of its outstanding shares for the trailing 12 months.  What a great way to see conventional wisdom in practice.
(click to enlarge)
It's pretty easy to see that the buyback companies have significantly underperformed this year in a raging bull market.  The point here is not to say that this idea never works, but it appears to provide no measurable edge at this point.  It may outperform the next 12 months for all I know.  Couple this with someone who doesn't understand how options work and you're going to have someone who is not only underperforming, but losing money.  The long winded point here is to be very cautious when you read articles from what appear to be reputable sources.  When you see someone describe the advantages of buying calls instead of the underlying stock, rarely do you see them mention that it is quite possible to lose 100% of your investment!  This is possible, but highly unlikely with the underlying stock.  And this is coming from an option advocate, folks.  I love them, but I think they're sold to the public in the wrong way.
 
In other news, another strategy ETN has been released by Morningstar.  The ETN tracks a Morningstar Index called the "Wide Moat" index launched in April 2007.  Wide moat refers to stocks that Morningstar's analysts feel have significant competitive advantages.  We'll see how this conventional wisdom pans out.  The ticker symbol is WMW, the press release can be found here.

Welcome Back Volatility

by billb 18. October 2007 11:00

And in "up your nose with a rubber hose" news, volatility is back.  The earnings reports after hours on Tuesday made it look like we were going to be off to the races on Wednesday.  The markets closed mix and well of their highs and lows.  What's a bit puzzling is the VIX actually went down on Wednesday and is now below 20 again.

With the price uncertainty demonstrated on Wednesday, I can't help but think that volatile times may be here again.  As I mentioned yesterday, earnings were mixed and the market close reflected that precisely.

The bulls have been proselytizing to us that things are up because of earnings.  We can ignore the credit crisis, commercial paper problems (what happened there?  Nothing), commodity prices and the plummetting dollar because earnings will save us.  I'm not a doom and gloomer, but S&P earnings have dropped off for the first time since the bull started 5 years ago.

Keep in mind that I'm still very much long at this point, but I'm looking for more short leaning positions.  I'm not looking for a crash or even a correction, but some retracement is likely in order.

Today's price action and lack of reflection in the VIX is cause for concern to me.  Expect to see a bearish spread in the coming days.  If the VIX stays low, long vega positions will be attractive.  In the event of a sharp turn lower, vols will spike and if the position leans bearish, you'll get a two-fer.  Of course, being right on two things means that you can be wrong on two things.  As always, exercise caution and do what makes sense given your situation.

Earnings Season

by billb 17. October 2007 11:05

With last night's earnings, it appears as if tech is on top for a reason right now.  The S&P companies, especially financials, are not impressing while tech is dazzling.  Two days does not make an earning season, but this is an interesting pattern and if it persists, I'm not sure where things will go.  The Dow has been leading over the last year, but recently, the Nasdaq has taken the helm.  Will we see a big divergence between the industrials and tech?

In unrelated news, MW keeps getting butchered and it looks like we may get some relief (still holding NVDA which has seen a pop thanks to YHOO and INTC).

And finally, the posts and thoughts may be a little light this week.  We're trying to put the wraps on RightEdge 1.1.

Stock Picking in Review

by billb 13. October 2007 13:17
 
What a difference diversification makes. I was highly focused on the MW trade that had gone pretty bad as I mentioned on Thursday. If you missed it, MW lowered guidance along with a bunch of other retailers, and the stock got hammered. The hammering continued into Friday, but I completely missed the fact that other stocks in the portfolio were up strongly. Maybe they weren't up 10 or 15% but they did well. As a result, the final numbers for this week are not as bad as I expected. All of the major averages were up again slightly with the Dow laggong at 0.19%. The S&P 500 eked out a gain of 0.26% and the Nasdaq, even though pummeled on Thursday outshined them all up 0.90%. Here's how the picks fared.

I'm pleased to see that we squeezed out a positive week. If MW hadn't have warned, I'm sure we would've done a whole lot better, but such is life.
 
My trading systems in the past typically buy stocks that have been hammered. They are typically "mean reversion" type systems that attempt to capitalize on sell offs that have been overdone. I'm working now on some systems that may be useful to these picks where extreme sell offs may warrant some additional exposure. I don't dwell too much on the past, but we recently dropped JNS which had been a stinker (and honestly, I was happy to see it go), but now it is up around 10% above from where I initially purchased it. The point of the exercise is to find stocks that have the propensity to go up. They may not go up today or tomorrow or ever, but they'd rather go up than down in most cases. In this case, it may make sense to get a bit more MW.
 
Let me make this clear though, I'm not a proponent of eternal averaging down. Sometimes you're just not right and it's time to move on. My rule is three strikes and you're out.   I'll usually buy something that has been beaten, buy some more if it gets beaten some more. After that, I'll be a bit gun-shy, but will take one more dip. After that, I'm out. There is no point from a psychological or monetary standpoint to stick with the Titanic like the band.
 
This all brings me back to the original point of the picks. These are here to help me identify stocks that are "good" stocks. These are stocks that I can have confidence in. So when I do double or triple up I have the confidence that they are likely to bounce back. No one is saying that they will absolutely bounce back.
 
Enjoy your weekend!
