I have been saying things like this ( Short vega, etc ) for so long, I should realize that on the surface it does not make too much sense.

What I am talking about is how your current position reacts to one of the greeks. Let’s take short vega as an example, also called negative vega and short volatility they mean the same thing. Your position makes money if if volatility decreases.

[EDITED - Thanks Michael . Man, I need to find a proofreading 101 class]

Long Theta is a little bit stranger. Long theta means your position makes money as time passes. Time usually moves forward, so we pretty much know long theta will help our position. How much it help depends on other factors.

SO here is an example. The Mar 08 250 BIDU put closed at 16.90 ( 2/15/08 ) with BIDU closing at $259.10. The position is short theta in that it loses money over time. The amount it loses increases every day, with the rate increasing the most in the last 30 days.

Using a option calculator, and advancing the date to Monday ( 2/18/08 ) , we have a price of $16.03. A loss of about ~$29 a day. Now, this is if implied volatility and price of the stock do not change. Both of these are unlikely, since the implied volatility on Fridays gets messed around.

So the BIDU 250 PUT is short theta in that the option is losing $29 a day.

Personally, I like long theta trades. IF / WHEN you are wrong in your equity selection, you have time to adjust your trade without have to pay the “vig” everyday.

I want to use Michael’s BIDU call as an example. Michael Trader bought a Mar08 250 Put. Today it closed at $21.50. Since the put is out of the money, the price is heavily influenced by the pricing model which is determined by the future volatility, or rather the guess of the future volatility.

So what does this mean for the price of Michael’s put ? BIDU’s earnings were after the close and they came inline with expectations. Well, since during the trading day, we could not predict what the earnings would be ( or what the market reaction would be ) traders charged a higher premium ( higher volatility ) to sell options to cover their a$$’es in the case of a huge move. So now after earnings, option sellers would not charge such a high premium for options.

So after earnings, even if the stock price does not change, the price of the option will probably fall. There are lots of other things that could happen, but I would not go into those here. We can expect , all things being equal, Michael’s put opening lower. Sometimes the volatility crush can be huge, sometimes not that great. But that is the nature of trading.

And to Michael , dude, we have all been there. Good luck.

I don’t post on this blog much because my trading is , frankly boring. I do the same type of trades for the most part day in and day out. Very few speculative trades. Maybe I will start posting option book reviews or something, but for now, I have something to post.

I want to say that when I first started trading options, I traded like a drunken monkey also. I started out with 5K , coincidentally, to learn how to trade. I ran that $5K up to $12K in something like 6 weeks with just a couple of trades. I was really just guessing. I did not have a defined edge, I did not have a plan. I just traded on hope. I would buy options and just hope the stock would go my way ( hope was my trading plan ). After I lost all the money I made and more in the next four weeks, I took some time off, and figured out what my edge was and I have been much more successful since that time. I think blowing out your account CAN be a good learning experience, although an expensive one.

So anyway, back to the post.

As for trading outside your size, position sizing is important. Mainly to keep you in the game. To really make a lot of money , you can swing for the fences, but you have to realize that you will strike out more. None of us can predict the market 100%. We all will have losses and drawdowns as you pointed out. The point with position sizing is so that you will be able to take a few losses in a row and still have enough money to trade. Lose 20, 30 or 40% percent of your account, makes it that much harder to come back and profit. Position sizing does not mean not trading the money in your account, but it does make you spread out your trades over different stocks. I am almost never 100% in the market, I have gotten close a few times. I usually leave some in my account so I have cash to adjust positions. I will have as many positions as my position sizing allows.

A trading plan has a lot to do with psychology. We all trade for profit of course, but a trading plan for your trades help keep you sane before and during the trade. When I enter a trade, I write down my objective & reason for the trade. Then I write the reasons to exit. What happens during a trade is you get all wound up in the emotion of trading and it makes it hard to trade with disciple. By writing down why I entered the trade and what my exit strategy is, I don’t start flip-flopping on my decisions mid way through the trade.

As for your BIDU trade , I think it was a good trade on picking the direction. BIDU is in a downtrend, and has some support at the $240 level which it looks like it has passed on the downside. IMHO, I would be first looking at at vertical spreads because of the high implied volatility and earning due this week.

( click to enlarge, 11.FEB.2008 before the open )

If you notice, the volatility falls after earnings, which affects the price of the options. Vertical spreads help you counter the effects of volatility contraction and theta. In a vertical spread such as a bear put spread, you have two options One long and one short at different strikes for the same expiration. Say the volatility of the option falls and the option you purchased falls in price. The option you sold would also fall in price, reducing the effect of volatility contraction. On the theta side, you would gain some from the option that you sold, and lose some from the option that you purchased.

I don’t trade vertical spreads that often, it is not my style, I mainly trade time spreads. I do take trades like this on a more speculative basis every blue moon. Now, if you are looking at a large quick move ( I assume south ) on BIDU, cheap OTM options would be great because of the leverage. If you expect a small move ITM options would be better. You picked an ITM options, so I assume you are expecting the stock to move lower but not plummet after earnings. The delta on your put is 53.5% ( as of Monday morning ), so a $10 move in BIDU, produces $5.35 ( roughly ) for you.

The implied volatility will probably decrease after earnings ( 2/13 after the close ) so the price of the 250 BIDU option you purchased may decrease even if the stock price does not move.

Oh, and as for the 100K , that is not realistic in your case. It was just a number off the top of my head. You can get deals less than 100K of equity. Since your commissions will come down a lot when you start trading larger sizes, and no pattern day trader rule ( which stops at 25K equity ) it makes it a lot easier.

All said and done, I am 75% an income trader, and you will not get from $5K to $100K in a year income trading. So go swing for the fences, and I hope you make it.

So let’s look at the Butterfly

Volatility: Negative. We want options with friggin’ high IV’s. IV drops will help us.

PLAN I believe the market overreacted to the news. I expect the stock to move back up, and the IV to drop.

IVWCG’s IV spiked from the 20’s ~30’s to the 150’s ~ 200’s which is a lot. Volume is light, so there is more of a change for mispricing. That is retail traders paying more than they should. Or pick off paper, I don’t know which.

EXIT Lift either leg, once most of the premium is gone. Tighten stops and try to be out a week before expiration unless something is WAYYYY out of the money ( on the upside preferably )


WCG 45 C 1 1.7000
WCG 40 C -1 2.6000
WCG 40 P -1 9.9500
WCG 35 P 1 6.6500

Premium recv was $90 from one spread, and $330 for the other spread. Leaving me out in the wind for $80. I am looking for a IV drop to bring this one into the black. I don’t plan on seeing this one to the end. Two weeks max and I am out.

Well, AAPl earnings were about to come out, and i bought an iron condor. Crazy you think ? If AAPL has great earnings, I am screwed. Well, yes and no. While IC’s are long theta, they are also short vega. There is still a month left in the trade, and I probably, err , will not hold this one.

So AAPL’s volatility was up pretty high ~55%, from the usual 40%. So I wanted to sell, and we have vol crush afterwards. With such high IV, the profit margin widened signifigantly. My margin is $5 a spread, and if I can pull $0.7 out of the trade, I will be happy. 14% return in a day at least.

Iron Condor AAPL NOV07 200/195/155/150

That is ssot of a shorthand for:
BUY AAPL NOV07 200 CALL
SELL AAPL NOV07 195 CALL
SELL AAPL NOV07 155 PUT
BUY AAPL NOV07 150 PUT

Getting in Credit $1.65 ($0.75 on the call side,$0.90 on the put side ) risk $3.35, for a risk/reward of 49%. You may ask why is the risk not $8.35. The reason is for that to happen, AAPL would have to trade above 195 AND below 155 at the same time.
