• “Explaining” Random Variation

  When I was a reporter covering Cisco Systems Inc. in the late 1990s, it was my job to talk to several analysts a day to find out the latest bit of news that might move the networking company’s share price.

  If the stock moved more than 2% on any uptick in volume, I had to write a story explaining why. After dealing with that every day for about three years, I realized the overwhelming majority of analysts had no better clue than I did about what was moving Cisco’s stock.

  The “explanations” you hear from media often are just as useless as horoscopes. A bunch of meaningless words presented in the hopes you don’t realize they are empty words.

  The talking heads (and writers) need to say something. It would be much more useful if they took the time to do some research and put in some thought but they seem to be driven by the need to fill space instead of the need to inform.

• Retirement Portfolio Allocation for 2020

  The markets continue to provide difficult options to investors. In the typical market conditions of the last 50 years I think a sensible portfolio allocation was not that challenging to pick. I would choose a bit more in stocks than bonds than the commonly accepted strategy. And I would choose to put a bit more overseas and in real estate.

  But if that wasn’t done and even something like 60% stocks and 40% bonds were chosen it would seem reasonable (or 60% stocks 25% bonds and 15% money market – I really prefer a substantial cushion in cash in retirement). Retirement planning is fairly complex and many adjustments are wise for an individual’s particular situation (so keep in mind this post is meant to discuss general conditions today and not suggest what is right for any specific person).

  This post was written before #covid19 became the enormous economic clamity it has become. Based on the poor preparation to fight Covid19 by the USA and Europe I sold some stocks and reduced global exposure and emeriging market exposure.  I didn't reduce it to zero or anything close to that, but as I say I am usually overweight stocks and I had reduced how much I was overweight due to high stock valuations and with the likely Covid 19 problems I further reduced stocks to make my portfolio probably even a little bit underweight stocks (but still over 50% stocks).

  I am more active than most people should be with their investments (I think it works for me but maybe I should be less active too, I just pay much more attention than most people and feel I can make some adjustments that are sensible.).

• Finding Great Investments Keeps Getting Harder

  In some ways investing recently has been pretty easy, anything you have bought (almost) goes up – and usually goes up a lot. But when looking for bargains to invest in, it just keeps getting more and more difficult in my opinion.

  ...

  Overall I am going much more into cash as a safe haven than I have before. Normally I am extremely overweight stocks. Even today I am still overweight stocks compared to the conventional wisdom

  ...

  While the markets are giving investors great returns finding good buys is becoming more and more difficult (at least for me). For example, my 10 Stocks for 10 Years (2018 version) has done very well. But several of those stocks are much less a bargain today that they were. Apple is up from $225 to $450. Danaher from $103 to $206. Amazon from $2,000 to $3,150. Tencent from $43 to $68...

• Most Valuable Companies in the USA Compared to the Total Market Capitalization

  In general investing in low cost index funds (like Vanguard’s index funds) is a very sensible strategy. I personally invest mostly in individual stocks. I see stocks such as Microsoft and Costco that are attractive businesses to invest in but the stocks are so costly I hesitate to invest. In addition, I already am over-invested in mega-cap companies (my largest holdings are Apple, Alphabet and Amazon, about 36% of portfolio). So avoiding other mega-caps makes some sense to me.

  ...

  10 year returns: Apple (up 1,068%), Alphabet (up 424%), Amazon (up 693%) and Microsoft (up 1,090%). FYI, the total USA market index fund (VTI) was up 187% for the same 10 year period and the S&P 500 index fund (VTI) was up 204%.
