This article examines two oscillators - the Moving Average Convergence-Divergence (MACD) and the Relative Strength Index (RSI) - to see if these rules are profitable. Using 60-year data of the London Stock Exchange FT30 Index, it is found that the RSI as well as the MACD rules can generate returns higher than the buy-and-hold strategy in most cases.
This paper investigates the consistency of the least squares
estimators and derives their limiting distributions in an AR(1)
model with a single structural break of unknown timing. Let
β1 and β2 be the preshift and
postshift AR parameter, respectively. Three cases are considered:
(i) |β1| < 1 and
|β2| < 1; (ii)
|β1| < 1 and β2 = 1;
and (iii) β1 = 1 and |β2|
< 1. Cases (ii) and (iii) are of particular interest but are rarely
discussed in the literature. Surprising results are that, in both cases, regardless of the location of the change-point estimate, the unit root
can always be consistently estimated and the residual sum of squares
divided by the sample size converges to a discontinuous function
of the change point. In case (iii), [circumflex over beta]2
does not converge to β2 whenever the change-point estimate
is lower than the true change point. Further, the limiting distribution
of the break-point estimator for shrinking break is asymmetric for case
(ii), whereas those for cases (i) and (iii) are symmetric. The appropriate
shrinking rate is found to be different in all cases.
a b s t r a c tThis paper estimates the value of superstitions by studying the auctions of vehicle license plates. We show that the value of superstitions is economically significant, which justifies their persistence in human civilization. We also document the changes of the value of superstitions across different types of plates, across different policy regimes, and across different macroeconomic environments. Interestingly, some of the changes are rather consistent with economic intuition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
