    Leveraged ETFs don't hurt you if you get the direction of the move "right."

    correct, I saw no time

    correct, I saw no time delay.  However again your losses and draw down will also be 2X as large, not just your gains.

    rikkwan and ETF rebalancing

    Posted by cubby on 30th of Apr 2011 at 05:41 pm

    So a rigorous approach to the SSO vs. SDS choice creates two ETF pairs and a new question has arisen.

    Let's recap. Folks may desire leverage and seek alternatives to SPY, but may also have good reason to avoid futures. Besides the crazy higher risk with ES et al, there is less price detail for opening, high, low, and closing price, since these vehicles trade outside "regular" market hours. One should expect markedly different performance for futures, so much different even that a comparison may not be worthwhile. I'll not do it.

    So on to the question. Whenever one receives a LONG signal, then one either buys SSO or shorts SDS. Let's name this the LONG pair.

    And likewise, for a SHORT signal, one buys SDS or shorts SSO for 2X leverage. (SHORT pair)

    Thus we have the interesting question to explore with ones trusty spreadsheet: WHICH APPROACH RESPECTIVELY FROM THE TWO DIRECTIONAL ETF PAIRS IS MOST EFFECTIVE?

    The mathematical work is clear. One must segregate long and short signals into their respective groups, all the longs together and the shorts in a separate group. Next one matches the price data for these actual trades from the back-test history to/with the corresponding EFT pair and then simply calculates the best performer.

    It is not a given that the same approach will win for both signal-types. The numbers will not lie.

    More will be written on this later. For rest of today, I have to prepare to give a science lecture for tomorrow. Feel free to begin the work as it is laid out here on your own initiative(s).

    Best regards, Cubby

    Leverage

    Posted by zach06 on 30th of Apr 2011 at 06:22 pm

    THe biggest problem with using leveraged ETF's or Futures... is that you really don't know how much you are risking...   For the sake of argument.. I think Matt said that the biggest drawdown was 3 percent?    This would mean 3k on 100,000   Keeping 97 percent of your capital "intact" on a loss..  Do you know what the proper amount to invest in the ETF or Futures contracts?    

    I personally trades 3 futures contracts when Matt said to go long.   I was underwater for awile...  I added 3 futures contracts   and then added 3 again until Matt said to go flat.    I was up over 14k at the end of the flat signal.    I found out that if was trying to invest an equivalent of 100,000k  was was putting way to much at risk.   I did get "lucky" with the trade in my opinion...and will cut back the next time.   There is probably no easy way to figure out how much you should put into a leveraged ETF or futures per 100k.      

    Does anyone know what the average percentage gain per trade was?

    Calculating Risk Using Futures

    Posted by pdquig on 30th of Apr 2011 at 08:05 pm

    For futures you look at the nominal value of the contracts you trade. For ES it is $50 x Index point value, or as of Friday's close, $68,175 per contract. In other words, in your example trade above, your 9 contracts was the equivalent of about a $600K position in SPY depending upon where the index was when you entered.

    Since the system doesn't use stops, you have to look at the maximum losing trade to determine how much you are willing to risk. Or, use the mid-trade maximum drawdown to determine how much heat you could stand before bailing on the trade. In either case, the first thing that you need to do is to determine for yourself what the maximum loss to your account that you are willing to take on any one trade.

    ES example:

    Let's say you have a $100K account and are willing to lose no more than 3% ($3,000) on any one trade. If the system's historical maximum losing trade was 3.36%, you would divide your $3,000 by 0.0336 (3.36%). The result is $89,286. That means that you could comfortably trade only one ES contract (again, worth $68,175 right now). When your account gets to $178.6K you could add another contract. Or, you could add more contracts if your risk tolerance is higher.


    Make sense?

    ok..but....

    Posted by zach06 on 30th of Apr 2011 at 08:58 pm

    for simplicity... the 68,175 doesn't really matter...    The value would imply that you can lose 68,175 if the market went to zero.      I would say that a 20 point stop overnight would be good for a hugh overnight lose.   Hence 1000.00 per contract.    The nine contracts was an overload on my part.      The bigger problem is that you can't by "fractions of contract"  like you can by SPY shares in odd numbers.     The SPY also doesn't evaporate in thin air like futures do.  YOu can buy and hold if you really get in trouble.     I would probably go long one futures contract in the future and add one at each entry point... moving stops as necessary and putting my initial stop at 1000.00 or 20 points... to simplify things...    On Matt's last trade that would have made me a profit of a little under 5000.    I forget... but I think my overnight margin on futures is around   3500 per contract.

    The other way of looking at it...

    Posted by pdquig on 30th of Apr 2011 at 10:19 pm

    If you're using stops then it's much easier: just figure out how much you will lose if your stop gets hit. If you only want to lose $1000 max, then you can just divide $1000 by $50 to get your ES stop points value. $1000 / $50 =

    20 ES points for one contract

    10 ES points for two contracts

    4 ES points for five contracts, etc.

    not really.

    Posted by zach06 on 30th of Apr 2011 at 10:42 pm

    I was talking about 20 points per contract..  ANyone who would leave a 4 point stop overnight deserves to get stopped out or shouldn't enter the trade in the first place.         Don't forget... there is more gaps up overnight than gaps down.

    I think....

    the Dow is going to "0", no wait maybe to "30,000" but then gold is going to $10,000 an ounce and silver is going to $1,000 an ounce so what does the Dow matter? on the other hand, maybe gold is going to $500 again and silver is going back to $8....but then where does that leave the Dow?  Gas at $4 today in my neck of the woods but yet the local shopping mall was packed and I mean PACKED today and restaurants have been busy even on Tuesdays and Wednesdays.....Japan earthquakes, PIGS blow ups, Syria shooting everyone in sight, tornados, floods and a Fed with a blank check to do whatever they want....

    now that it's clear as a bell, what should I be doing on Monday again?  Smile

    Maybe the safest way if you are going to use SSO and SDS is to only short them with the SPY signals.

    but why bother shorting the inverse funds for the SPY system when matt substituted the trades -- and cubby did also -- and SSO works as well or better than SPY?  IF you want that additional exposure, of course. 

    the question was whether you

    Posted by bkout3 on 28th of Apr 2011 at 12:16 pm

    the question was whether you could pick up some extra return by shorting SDS to go long or SSO to go short in order to benefit from leveraged ETF tracking errors over time. However as per the earlier post maybe since the system is "right" so often the ETFs will move in the right way and tracking error will not be an issue

    Posted by stevedfw on 28th of Apr 2011 at 12:11 pm

    Just threw that out for discussion. So what is being proposed is to use SSO for long and short trades and NOT using SDS at all (I.e.for short signals), correct?

    I assume that if we can substitute SSO that we can therefore short via SDS ?

    ditch - you would think

    Posted by Michael on 28th of Apr 2011 at 09:59 am

    ditch - you would think so, and probably, but you'd have to go back and list the trades to know for certain.

    Thanks, Matt.

     

    Now, if you have the time, it would be interesting to see what the results would be using BXUB, which is the 3X SPX etf.

    we can do these comaprisons

    Posted by Michael on 28th of Apr 2011 at 09:44 am

    we can do these comaprisons ourselves -- matt just got to it before I did it this weekend..........  cubby on the blog did it also...........  Just take the trade list and go back trade by trade and substitute the levereged fund of your choice on a spreadsheet.....................

    Great stuff as always Matt,

    Great stuff as always Matt, much appreciated. I'm curious if the same holds true for the ES mini as well.
