QUOTE OF THE WEEK

Risk and time are opposite sides of the same coin, for if there were no tomorrow there would be no risk. Time transforms risk, and the nature of risk is shaped by the time horizon: the future is the playing field. PeterL. Bernstein



RETIREMENT FINANCE AND PLANNING

Although many legal boundaries stand in the way, instead of receiving a cash lump sum, retirees could instead receive a balanced portfolio of ETFs allocated based on a specific risk profile. 

The holy grail of retirement income planning is finding strategies that enhance retirement efficiency – strategies that simultaneously allow you to spend more and leave behind a legacy you can be proud of, in a way that other strategies may not. The definition of efficiency varies from person to person as it depends on how long you will live.  As mentioned in the first point, a number of strategies can enhance efficiency over the long term (but not necessarily the short term) with more spending and legacy.  

Results indicate that failing to account for more realistic earnings curves throughout the life-cycle may overstate SSRs for lower-income households while understating SSRs for higher-income households and understate SSRs for younger households while overstating SSRs for older households. Furthermore, historical SSRs of 10% or less are found for all but the highest income households after accounting for more realistic earnings curves and Social Security benefits. 


MARKETS AND INVESTING

introduction to … ever-growing list of irrational or, at least, slightly odd behaviours in the sphere of investment  

In Das, Markowitz, Scheid, and Statman (2010), an investor divides his or her wealth among mental accounts with short selling being allowed. For each account, there is a unique goal and optimal portfolio. Our paper complements theirs by considering estimation risk. We theoretically characterize the existence and composition of optimal portfolios within accounts. Based on simulated and empirical data, there is a wide range of account goals for which such portfolios notably outperform those selected with the mean-variance model for plausible risk aversion coefficients. When short selling is disallowed, the out performance still typically holds but to a considerably lesser extent.   [not read]



ALTERNATIVE RISK

CTAs should not expect strategies with names borrowed from cute animals to work in the era of algo trading and machine learning; there is an expiration date to all strategies. Success requires continuous innovation. 

The profitability of a trend following strategy is based on the ability of early recognition of turning points in the stock price trend. However, since the stock price is noisy, the noise complicates the identification of the trend and trend turning points. To remove the noise, traders use right-aligned moving averages. These moving averages have the following two most essential properties. First, the longer the size of the averaging window, the better a moving averages removes the noise in the stock prices. At the same time, the longer the size of the averaging window, the longer the lag time between a turning point in the intrinsic stock price trend and the respective turning point in a moving average. 

Strategic asset allocation is the policy you would choose if you thought risk premia were constant; tactical asset allocation is the changes you would make if you believe risk premia are time-varying.

We find that the most compensated options to sell on the S&P 500 surface per unit of stress-test loss are front-month options with strikes near-the-money and moderately below the index level. We apply these results to evaluate return expectations for short volatility strategies, potential added return from option selection, and implications for variance swaps.   [comment: this paper backs my amateur strategy and positioning.  Near dated options somewhere between .5 and 1.5 standard deviations in oom strike seem to be a sweet spot in both the paper and my experience]

It may be seen from the above performance table that no strategy beats buy and hold in terms of CAGR performance. The 60/40 portfolio has the highest CAGR, Sharpe and MAR (CAGR/Max. DD). From the timing strategies, PSI5 has the highest Sharpe and CAGR is close to that of the 60/40 portfolio. Long-short 50/200 cross has been a disaster with negative performance.  



SOCIETY AND CAPITAL

The roots of this revulsion [to lending at interest] run deep, and across cultures. Vedic law in Ancient India condemned usury, and rulers routinely capped interest rates from Ancient Mesopotamia to Ancient Greece. In Politics, Aristotle described usury as ‘the birth of money from money’, and claimed it was unnatural because money was sterile and should not ‘breed’. 

The fifth view is perhaps most favored by transportation experts, but is also generally reviled by the traveling public and the officials they elect: using prices to balance the supply of and demand for travel…The economics of traffic congestion is clear-cut. Those stuck in traffic naturally prefer to think of congestion as caused by everyone else, but everyone who in the jam is part of the problem.When you are in a traffic jam, those in front of you in line are imposing costs of time delay on you, and in turn, you are imposing costs of time delay on all of those behind you in line. Those costs are a form of pollution, a "negative externality" as economists call it.   If drivers were required by road pricing to pay these peak-load costs that they impose on others when the roads are congested, many of them would find a way to shift the time or route or mode of their commute, or to telecommute at certain times. 

The results imply that retail dispensaries lead to reduced crime in the neighborhoods where they are located. Reductions in crime are highly localized, with no evidence of benefits for adjacent neighborhoods. The spatial extent of these effects are consistent with a policing or security response, and analysis of detailed crime categories provides indirect evidence that the reduction in crime arises from a disruption of illicit markets. 

Given that we derive real per capita personal income by dividing nominal income by cost of living, one might expect that the most costly cities have the lowest adjusted incomes. While that is sometimes true, it’s not always the case. For example, San Jose and San Francisco, California, and Bridgeport, Connecticut, are each in the top ten for both most expensive cities and highest-earning cities. Similarly, McAllen, Texas, has the lowest real per capita personal income of any MSA, about $27,000, despite being one of the 20 cheapest cities in the country. 

we still think the scope around the discussion of quants is far too small. What we find interesting isn’t classifying the money flows into quant strategies, but discussing what people are doing in the quant space overall; who and how algorithms are being built; where the lines blur with FinTech; and the lineup of players in the space.  Sure, there are the big banks expanding their quant departments with recent grads with PhDs and degrees in computational finance (that’s an engineering degree if you’re all wondering); but in this consumer driven economy, it’s not just them and big hedge funds rushing into the quant world. Mom and pop investors are taking an interest, as are aspiring computer programmers and coders.  

During the global financial crisis, Alexis Stenfors was a rogue trader at Merrill Lynch, cooking the books to hide the millions he lost in the market. He recounts his experiences in a new book, Barometer of Fear: An Insider’s Account of Rogue Trading and the Greatest Banking Scandal in History. Stenfors is now a senior lecturer in economics and finance at the University of Portsmouth in England

But the designers of state-run auto-IRA plans fail to consider three questions: Do the poor need to save more for retirement? Will state-run auto-IRA plans increase net household savings? And, after accounting for interactions with means-tested government transfer programs, will state-run auto-IRA plans make the poor better off? The answer to all three questions may be “no.” 

Every corner of the U.S. was hard-hit by the Great Recession, but the varying makeup of local economies resulted in different effects on individual cities, states, and regions. Areas that are reliant on economic necessity—say, healthcare and waste management—may fare better during economic downturns than areas that are reliant on economic prosperity—say, tourism and construction. In 2008, the recession particularly disrupted the construction industry. According to the Bureau of Labor Statistics, the percentage of jobs lost in that industry, 19.8%, exceeded those of all other nonfarm industry supersectors. 


The government’s latest report on Social Security is bad enough. Trends in income inequality and health care make it worse.
