Goodbye China

This is my last day here.

I liked it here. It was comfortable. Perhaps too comfortable. I would have stayed here forever. It was an ideal retirement.

Oh well, back to the Ghanaian project, assuming the current market turmoil hasn't derailed the financing.

  1. Am rather sorry to hear that.
    Your comments on the China scene were always informative and gave a glimpse of a country in transformation.
    Perhaps the same is true about Ghana? I look forward to your upcoming posts.

    Meanwhile, thank you for your postings and good luck!

    1. Ghana is in transformation as well, but not as far along as was China. I am looking forward to seeing what changes there have been in the five years since I last went there.

    2. I just saw in a video where JIm Rogers bought stocks on the Zimbabwe stock exchange. It is in transition too. The video was a few months old.

      I think the reasoning using his phrases include: That it is low priced because it is a hated market and he thinks it has upward potential. He previously said, that eventually the old president would be out. And now he is. He has traveled through Africa a few times and has bought in similar situations when he sees an improvement. Those stories I think are in one or two of his travel books.

      He says, "Only invest in what you know."

      He also had invested in China.

      Perhaps there might be similar or better in Ghana?

    3. If buying stocks it is paramount to have learned some accounting in order to understand the financials statements. Accounting and double entry bookkeeping can be self learned.

      Here is Jim Rogers opinion on being ahead of 98% or 99.5% of other investors, from his book, "A gift to my children."

      https://books.google.com/books?id=w1zKBAAAQBAJ&printsec=frontcover&dq=a+gift+to+my+children&hl=es-419&sa=X&redir_esc=y#v=onepage&q=financial%20statements&f=true
      I looked up "financial statements" in the book to find the quote.

      He also says to talk to the suppliers, customers, and competitors of the company.

  2. I wish you well, good health, good friends, and prosperity in Ghana.

  3. Micky Man,

    This is a short version of a comment I made that I think got clobbered.

    I color the line to make phase plots more clear. For economic data, I color by decade. With gnuplot it is as easy as adding an other parameter for the line color to be, date/10.

    The graphs are much more clearer. If I want to make them more clear some times I plot the line between points as arrows!

    Some times, I label every point with the date or every 5 or 10 year points with the date.

    These are graphs that are similar. (I did not read the paper.)

    I you want I can post example gnuplot scripts and commands. They can be educational or used directly.

    (This looks good graded. By my graphs are colored for a period of time, many of the following line colors have good contrast with the previous color.)

  4. Question for Mickey Man,

    Have you been using phase portraits and dynamic complex analysis methods for investing or speculating in the markets?

    Do they work well? Roughly how well?

    Do they produce disastrous trading losses too?

    I ask, because, I have been playing around with such things for a while with thoughts of profit but have not made any trades. But, mostly I have been applying it to economic data. Should I be more motivated and do more on items that can be traded?

    1. I actually had some successes, and made decent money on a few stocks. I was able to avoid some losses. Where the losses happened were catastrophic failures of a previous success story, and being forced (for personal reasons) to liquidate into a weak market.

    2. Very interesting. Thank you for your candid answer.

  5. I realize you are busy with a move so no need to answer my questions now.

  6. I see you also do colored line graphs. I just found one of yours. Yours looks good:

  7. Here is the secondary source rather than from me third hand. I just ran across an interview of Jim Rogers that talks about two of the things I attributed to him saying.

    " CHEAP BUYS

    My approach is that I usually like to find things that are cheap, where there's a positive change taking place, then I do my research and make my investment.

    INVESTMENT GURU JIM ROGERS, on his style of investment
    "

    "I bought Zimbabwe shares two weeks ago. That's new, I didn't buy a lot. I haven't bought shares in Zimbabwe for about 25 years. It's a disaster but therefore cheap. What instigated me to start investing there again was that they completely abolished their old currency and started using US dollars.

    The real new future in Zimbabwe will happen when President Robert Mugabe leaves. He's an old man and he will leave some day, and that will be the real change."
