这个人叫karen bruton,去参加seminar,被人忽悠去念了博士,估计那种水货,读了
一年半拿了博士。

然后牛逼用一万刀起步,几年就变成四千多万美元。

当然,后面故事很精彩,大家看看

牛人介绍:



Background
Attended a $22K Investools PhD course that took 1.5 years.
Traded stocks using technical analysis from 2002 to 2007 with $10K capital.
Start non-directional trading using options from 2007 with ~$100K capital,
and made 50%.
Friends put in money to start 2008 off with $700K.
Made $41M profits by 2011, fund size was ~$80M.
As of May 2012, was managing around ~$160M.
Basic Strategy
Theta trader, tries to pull as much time value out as possible. Theta starts
decaying around 45 days.
When volatility is high, she keeps on selling and buying back the options to
capture the value.
Trading index options allow for non-directional play, as well as being able
to not be impacted by stocks’ earnings season.
Timeframe
Sells the options that expire around 56 days, or 8 weeks away. Usually like
to let the options expire when the month comes by.
Execution
Sells Put options (on a market downswing) that have probability of being in-
the-money of ~5% (TOS estimates that by looking at the one-year standard
deviation of the underlying and assumes a Normal distribution, so 5% in-the-
money is 1.64 standard deviations away)
Sells Call options (on a market upswing) that have probability of being in-
the-money of ~10%. Tries to sell the Call options above strong market
resistance levels.
Reason behind the 5% vs. 10% probabilities is that “the market crashes down
, not up”, then down moves are quicker, so to be safe the Puts need to be
further out.
The positions are legged-in, i.e. the Puts and Calls are not sold at the
same time.
Sells more Puts than Calls.
Position
Usually commits 50%-70% of net liquidity so as to leave ammo to manage
positions.
Problem Management
If an option gets to 30% probability of being in-the-money, the position
needs to be actively managed.
Any costs associated with fixing the problem (e.g. losses due to closing the
position), will be made up by selling more options to get the premiums to
cover the losses.
For example, if the market moves up, she may sell more Call options that are
further out (i.e. higher strikes), or sell more Put options at higher
strikes (higher compared to the previously sold puts).
When the market drops and volatility spikes (i.e. she is losing money on the
Puts she sold), the fact that the strikes were far away (5% probability of
being ITM) gives her time to assess and adjust her positions.
When the Flash Crash of May 2010 happened, she closed her profitable
positions and sold options further away (October, November months) to get
more time to assess the situation.
