Price Index 6 months

Price Index 6 months

I wrote this strategy hoping to start some discussion on value trading vs. day trading and also to give a different option to people with little time available.

I adapted a buy-and-hold strategy based on the price index 6 months with an long-only-entry. When the close of the day crosses above 144% to the price registered 6 months ago we go long and we hold the stock for 1 year (apron 254 bars).

As I said it’s an adaptation made for automatic trading!! With Italian stocks the results are very good but might be MUCH better if you used Price to book (P/B) and  Earning yields (EY) to confirm the entry. Running this strategy manually with the use of P/B and EY12 months, and using a portfolio, returned an average of 55% a year in the last 10 years (Only one year I didn’t beat the market).

    Very interesting but why 144%? What about the drawdown of the portfolio? The one from this single stock is already huge! 😉 

  2. Kenneth Kvistad • 346 days ago #

    I have never been wondering about long trades or made any due to overnight costs, butdo you think it still affordable for such long trades as months/years?

  3. gabri • 346 days ago #

    144% was just an adaptation to make the automatic trading. Any number between 140% and 150% is fine. You should take the 20-40 stocks with the highest 6 months Price Index and search their fundamentals to pick the right one. Drawdown are not really a factor when you buy and hold value stocks.
    This was actually a real trade I made but I bought only in September 2004 since P/B was 1.4 (expensive but not too bad for the market of that moment) and the other fundamentals were promising. What I wanted to prove is that there are bizilions of trend indicators on the various trading platforms but the real big wave worth surfing is the one started by the institutional investors and they buy GOOD companies for CHEAP. Price index (for momentum) and fundamentals are the only data they use. 
    Having a portfolio made with stocks selected with fundamentals leads to really high performances (they almost always beat the market), even better the one of this single stock.

    I buy stocks, hence a part of a business. For stocks there are not overnight fees. You find overnight fees for CFD and derivatives. On top of that I go LONG only. With my bank I pay approx 3.5 Euros everytime I buy and the same amount when I sell. It’s totally worth for me.

  5. Kenneth Kvistad • 346 days ago #

    Ah okay. You can make automated trading with stocks as well 🙂 ?
    I dident know that

  6. gabri • 346 days ago #

    I manually trade only but I decided to code this strategy to show that there is more than intraday trading and this “more” might lead to substantial gains with less work and stress (on the stress I am not so sure 🙂 )

    Hi Gabri,
    I realized screener with the specifications of your trading system. Do you give me feedback on its reliability? This is the code:
    // Price Index 6 months
    thr=44 // entry thresholdref=close[130]*(1+thr/100) // price entry levelcond1=(close CROSSES OVER ref)
    SCREENER[cond1] (Variation AS “% Var barra prec”)

  8. gabri • 343 days ago #

    I would personally  just make it like this:
    thr=44 // entry threshold
    ref=close[130]*(1+thr/100) // price entry level
    cond1=(close > ref)

    SCREENER [cond1] (ref AS \"Price index\")
    so you can see ONLY the stocks that meet the condition and they will be ordered by the amount of gain in the last 6 months. You want to pick the top 20-30 stocks in the list so the amount of gain is important. Like I already mentioned 44 is not a fixed umber. If you’d rather use a yearly return you can lower the threshold to 30-ish. The setting are very personal.

  9. gabri • 343 days ago #

    Also, don’t forget to make sure you are buying stocks with low Price to Book ratio.

  10. gabri • 343 days ago #

    I wrote the previous answer in a rush. Try this code:
    thr=44 // entry threshold
    ref=close[130]*(1+thr/100) // price entry level
    cond1=(close > ref)
    SCREENER [cond1] (pi6m AS \"Price index\")
    Now you will see the stocks that meet the requirement and they will be ordered based on their gains. Sorry for the wrong code of before.

    Thanks Gabri for your screener rework. I\'m working on producing the indicator to get the graphic signal on the chart. It seems to me important to understand when it signals in the six months considered by the trading system. Luxrun

  12. gabri • 342 days ago #

    non ho o capito di cosa hai bisogno?

    • luxrun • 342 days ago #

      Nulla di particolare! Scusa il mio inglese tradotto da google. Dicevo solo che sto provando a costruire l’indicatore che mi mostra a video quando scatta il segnale long, nei sei mesi che il trading system, prende in considerazione. Non serve a molto, ma forse aiuta visivamente. Grazie Luxrun

  13. gabri • 342 days ago #

    no problem per l’inglese. Ti posso fornire due soluzioni. La prima disegna la linea del 44% e quella del prezzo:


    return linea1 style (dottedline,1) as \"44%\",close coloured (205,0,0) as \"Close\"
    La seconda ti disegna il ritorno degli ultimi 6 mesi e quando passa il 44% ti segnala la zona positiva:

    return a,44

  14. luxrun • 341 days ago #

    Benissimo, grazie, molto gentile e disponibile! Lo provo subito.  Io avevo scritto questo codice (ma programmo poco e male…), per l’indicatore:
    // Price Index 6 months indicator
    thr=44 // entry thresholdref=close[130]*(1+thr/100) // price entry level
    // conditions to verify entry longc1 = (close CROSSES OVER ref) IF c1 THEN
    cross = 1
    return cross as “CROSS”

    • gabri • 341 days ago #

      Il tuo codice va benissimo, continua cosi’!! dovresti solo aggiungere una linea per fare in modo che cross non rimanga sempre uguale a uno:
      c1 = (close CROSSES OVER ref)

      IF c1 THEN
      cross = 1

      return cross as “CROSS”
      in questo modo ti da dei picchi quando avviene il cross over (e solo quel giorno). Oppure puoi fare cosi’:

  15. gabri • 341 days ago #

    c1 = (close CROSSES OVER ref)
    c2 = (close CROSSES under ref)
    IF c1 THEN
    cross = 1
    IF c2 THEN
    cross = 0

    return cross as “CROSS”
    In modo che cross rimanga uno fino a che il valore di gain e’ superiore alla soglia.

    Grazie, Gabri, per il tuo supporto e aiuto. Ti sono veramente grato! Continuerò a seguire il tuo lavoro! L

    Hi Garbri,

    Thanks for your share. This is a very interesting strategy.
    Does anybody know an indicator using P/B ratio to get sharpest results ?

    • gabri • 320 days ago #

      there is no way to get p/b data on PRT. Unfortunately you have to get this values from the balance sheet of the company you are planning to buy. What I do is just running a screener based on price index and check the P/B of the first 20-30 companies on internet.

  18. Alain Federmann • 320 days ago #

    Ok, thanks.
    That is what I thought.
    Pretty weird and such a shame a powerfull tool as PRT can not use few fundamental analysis statistics.

  19. gabri • 320 days ago #

    Ho knows, maybe in the future they will 🙂

  20. Miguel1980 • 319 days ago #

    Hello gabri ,

    well, with the results you mention, even with half those results, it does seem a very promising strategy. I totally agree on the fact that fundamentals can make or break strategies in the long run. In my opinion, using only TA or Price Action concepts is, to some extent, like playing casino: you can win, but is very hard to beat the market clearly and consistently.

    You say you use the P/B and EY metrics. No problem with the first but I have some doubts about the second, just, if I’m not wrong, the inverse of the overused P/E ratio, which in my mind doesn’t seem to be the finest of the tools when we think of forecasting the future price evolution of a stock. Looking forward to know your opinion/experience about it.

    As a guide on how your strategy works, could you run a screening for us interested, preferibly on an US market (Italy would be OK too, if you prefer so), and then explain which stock/stocks you would choose and why? When you have the time and just the once, don’t worry!

    Thanks for now.

  21. gabri • 318 days ago #

    Hello Miguel,
    The reason why I switched from trading to investing because I didn’t like to play casino anymore 🙂 You are right, EY is pretty much the inverse of P/E ratio and for many P/E is not a valid reference number but used properly raises awareness on what is going on. I suggest you to read the work of Shiller (a nobel price) and his use of a 10-year-PE to predict markets. I do not use only P/B and EY but I personally check all the balance sheet of a company and, if good, I try to buy at a low PE or PB. Unfortunately I cannot run any backtest because I cannot make a code to find cheap and good companies on PRT and also because you need to backtest a portfolio. Every single stock will lose at some point. Using this system will allow the portfolio to win.

  22. Miguel1980 • 317 days ago #

    Hi gabri,
    I was not asking you to run any backtest but a PRT screener on any market to find 20/30 stocks currently with the best (best according to your strategy) PI 6m index, and then to share some thoughts about which one to pick up, based on their P/B, EY or whatever. Simply following the thread of the post.
    But personal strategies are just that, personal, aren’t they?, so I won’t insist :- )
    Thanks for your time.

  23. gabri • 311 days ago #

    Miguel, copy. I just came back from vacation, I will pass you some data soon.

  24. gabri • 311 days ago #

    I will give you some stocks. I would buy (I probably will) Serneke group AB. I will wait for the following to have a good PI 6m: gelek group, awilco drilling, arteria sa.
