Concentrate on something you have an advantage &#8212; your own business, for example.

Someone will be right. Most will be wrong. Meantime, my strategy is to monitor the stocks I like &#8212; see list on right. I like their &#8220;stories,&#8221; some more than others. I tend to monitor them for &#8220;disasters&#8221; and for big price falls. If the stock falls 10% to 15% I&#8217;m out. I let them drop more if I like their stories long-term &#8212; e.g. Apple, Google, Nike, etc.<\/p>\n<p style=\"text-align: left;\">I have a collection of &#8220;speculations&#8221; &#8212; AGIO (up 21% one day last week, ATK (up 93% since purchase), GPRO (up 20% since purchase), ISIS (down 5% since purchase), Gilead (up 57%) and Mobileye (MBLY, down 2%).<\/p>\n<p style=\"text-align: left;\">I like some financials, e.g. LADR (up 12%, but going higher),\u00a0 NLY, (up 18%), both MasterCard (down 5.4%) and Visa (down 5%), but I own more of V because I like it better. I think Apple Pay will help V (and AAPL). I don&#8217;t like their volatility. For that I own Berkshire Hathaway, some Vanguard index funds and IVV, the iShares S&amp;P 500 Index ETF.<\/p>\n<p style=\"text-align: left;\">I don&#8217;t think stockpicking is especially satisfying.<\/p>\n<p style=\"text-align: left;\">Which brings me to weekend reading. A guy called Jeff Madrick wrote a book called &#8220;<em>SEVEN BAD IDEAS. How mainstream economists have damaged America and the world.&#8221; <\/em><\/p>\n<p style=\"text-align: left;\">I&#8217;m very interested because the economists are meant to protect us from booms and busts, like the sub-prime mortgage disaster of 2007, which led to the horrible stockmarket crash of 2008. The reality is that economists like Greenspan, Bernanke and Yellen have zero idea when we&#8217;re in a\u00a0 bubble and even fewer ideas when it&#8217;s about to bust, like 2008. Or what to do about lessening the pain for us and the world.<em><br \/>\n<\/em><\/p>\n<p style=\"text-align: left;\">If they can&#8217;t predict anything, clearly lesser mortals like you and me can&#8217;t. Hence I need an investment &#8220;strategy&#8221; which insulates me from the volatility. Sadly, I don&#8217;t think there is such a strategy &#8212; despite Wall Street&#8217;s heavy marketing of &#8220;non-correlated&#8221; investments. When things go awry, everything seems to go awry. The sub-prime mortgage crisis of 2007-2008 halved the value of commercial real estate in places as widespread as Portland, Oregon, Salt Lake City, Utah and Boston, Massachusetts, for example.<\/p>\n<p style=\"text-align: left;\">Paul Krugman reviewed the book. Let me start with some excerpts from his review:<\/p>\n<p style=\"padding-left: 30px; text-align: left;\">The economics profession has not, to say the least, covered itself in glory these past six years. Hardly any economists predicted the 2008 crisis \u2014 and the handful who did tended to be people who also predicted crises that didn\u2019t happen. More significant, many and arguably most economists were claiming, right up to the moment of collapse, that nothing like this could even happen.<\/p>\n<p class=\"story-body-text story-content\" style=\"padding-left: 30px; text-align: left;\" data-para-count=\"264\" data-total-count=\"650\">Furthermore, once crisis struck economists seemed unable to agree on a response. They\u2019d had 75 years since the Great Depression to figure out what to do if something similar happened again, but the profession was utterly divided when the moment of truth arrived.<\/p>\n<p class=\"story-body-text story-content\" style=\"padding-left: 30px; text-align: left;\" data-para-count=\"331\" data-total-count=\"981\">In \u201cSeven Bad Ideas: How Mainstream Economists Have Damaged America and the World,\u201d Jeff Madrick \u2014 a contributing editor at Harper\u2019s Magazine and a frequent writer on matters economic \u2014 argues that the professional failures since 2008 didn\u2019t come out of the blue but were rooted in decades of intellectual malfeasance. &#8230;<\/p>\n<p class=\"story-body-text story-content\" style=\"padding-left: 30px; text-align: left;\" data-para-count=\"611\" data-total-count=\"4846\">Matters are even worse when it comes to the performance of financial markets. Here the proposition that markets should get it right \u2014 that major speculative bubbles can\u2019t happen (bad idea No. 5) \u2014 doesn\u2019t just depend on conditions that clearly don\u2019t hold in practice, but is directly contradicted by evidence on herd behavior and excess volatility. Yet \u201cefficient markets theory\u201d has maintained its academic dominance. Eugene Fama of the University of Chicago, the father of efficient markets, still denies that financial bubbles even exist \u2014 and last year he shared a Nobel in economic science.<\/p>\n<p id=\"story-continues-6\" class=\"story-body-text story-content\" style=\"padding-left: 30px; text-align: left;\" data-para-count=\"269\" data-total-count=\"5115\">Still, all of these failings of mainstream economics were obvious long before the 2008 crisis. What has really come as news is the seeming inability of economists to agree on a policy response to mass unemployment. And here is where my quibbles with Madrick get louder.<\/p>\n<p class=\"story-body-text story-content\" style=\"padding-left: 30px; text-align: left;\" data-para-count=\"353\" data-total-count=\"5468\">No. 2 on Madrick\u2019s bad idea list is Say\u2019s Law, which states that savings are automatically invested, so that there cannot be an overall shortfall in demand. A further implication of Say\u2019s Law is that government stimulus can never do any good, because deficit spending by the public sector will always crowd out an equal amount of private spending.<\/p>\n<p class=\"story-body-text story-content\" style=\"padding-left: 30px; text-align: left;\" data-para-count=\"703\" data-total-count=\"6171\">But is this \u201cmainstream economics\u201d? Madrick cites two University of Chicago professors, Casey Mulligan and John Cochrane, who did indeed echo Say\u2019s Law when arguing against the Obama stimulus. But these economists were outliers within the profession. Chicago\u2019s own business school regularly polls a representative sample of influential economists for their views on policy issues; when it asked whether the Obama stimulus had reduced the unemployment rate, 92 percent of the respondents said that it had. Madrick is able to claim that Say\u2019s Law is pervasive in mainstream economics only by lumping it together with a number of other concepts that, correct or not, are actually quite different.<\/p>\n<p class=\"story-body-text story-content\" style=\"padding-left: 30px; text-align: left;\" data-para-count=\"836\" data-total-count=\"7007\">Now, it\u2019s true that the relative handful of economists claiming that stimulus can\u2019t possibly work, or that slashing government spending is actually expansionary, have a much higher profile than their numbers or their influence within the profession warrants. Why? Partly, the answer is that the news media \u2014 especially but not only partisan media like The Wall Street Journal\u2019s editorial page \u2014 have promoted the views of economists they like for political reasons. Partly, also, it\u2019s because politicians listen to economists who tell them what they want to hear. I\u2019m not saying that mainstream economists bear none of the blame; the decades-long retreat from Keynes has undoubtedly allowed old fallacies to make a comeback. But austerity mania has to a large extent spread despite mainstream economics, not because of it.<\/p>\n<p class=\"story-body-text story-content\" style=\"padding-left: 30px; text-align: left;\" data-para-count=\"314\" data-total-count=\"7321\">I\u2019d make a further observation here: Academic economists have much less influence in Europe than they do in America. Yet the policy response to the crisis, while poor on this side of the Atlantic, has been much worse on the other. Politicians don\u2019t need bad advice from economists in order to go off the rails.<\/p>\n<p style=\"padding-left: 30px; text-align: left;\">Such quibbles aside, \u201cSeven Bad Ideas\u201d tells us an important and broadly accurate story about what went wrong. Economists presented as reality an idealized vision of free markets, dressed up in fancy math that gave it a false appearance of rigor. As a result, the world was unprepared when markets went bad. Economic ideas, declared John Maynard Keynes, are \u201cdangerous for good or evil.\u201d And in recent years, sad to say, evil has had the upper hand.<\/p>\n<p style=\"text-align: left;\">You can read the entire Krudgman review.
