Extracting bull and bear markets from stock returns
Traditional methods used to partition the market index into bull and bear regimes often sort returns ex post based on a deterministic rule. We model the entire return distribution; two states govern the bull regime and two govern the bear regime, allowing for rich and heterogeneous intra-regime dynamics. Our model can capture bear market rallies and bull market corrections. A Bayesian estimation approach accounts for parameter and regime uncertainty and provides probability statements regarding future regimes and returns. Applied to 123 years of data our model provides superior identification of trends in stock prices.Markov switching, bear market rallies, bull market corrections, Gibbs sampling
Constructions and Packings of Bull-Design
A bull-design of order n is a decomposition of the complete graph Kn into bulls. Such systems exist precisely when n ≡ 0,1 (mod 5). The necessary conditions of the existence of bull-designs of λKn are the follows: λ ≡ 0 (mod 5) and n ≡ 0,1 (mod 5), or λ ≡ 0 (mod 5) and for all n. In this paper we showed the necessary conditions are also sufficient, and gave the minimum leave of the packing of the complete graph Kn.補正完畢國外Y紙本BG
The Doyen-Wilson theorem for bull designs
A bull is a graph which is obtained by attaching two edges to two vertices of a triangle. A bull-design of order n is an ordered pair (X,A), where X is the vertex set of Kn and A is an edge-disjoint decomposition of Kn into copies of bulls. In this paper, it is shown that a bull-design of order n can be embedded in a bull-design of order m if and only if m≥3n/2+1 or m=n. This produces a generalization of the Doyen–Wilson theorem for bull-designs.補正完畢國外SCI紙本電子版NL

Duration Dependence in Stock Prices: An Analysis of Bull and Bear Markets
This paper investigates the presence of bull and bear market states in stock price dynamics. A new definition of bull and bear market states based on sequences of stopping times tracing local peaks and troughs in stock prices is proposed. Duration dependence in stock prices is investigated through posterior mode estimates of the hazard function in bull and bear markets. We find that the longer a bull market has lasted, the lower is the probability that it will come to a termination. In contrast, the longer a bear market has lasted, the higher is its termination probability. Interest rates are also found to have an important effect on cumulated changes in stock prices: increasing interest rates are associated with an increase in bull market hazard rates and a decrease in bear market hazard rates.
