Optimal stopping stock market
In mathematics, the theory of optimal stopping or early stopping is concerned with the problem In the trading of options on financial markets, the holder of an American option is allowed to be the dividend rate and volatility of the stock. Abstract. A class of optimal stopping problems for conditioned random walk is discussed in terms of selling strategies for the stock market. A class of optimal stopping problems for conditioned random walk is discussed in terms of selling strategies for the stock market. 0. Introduction. The stochastic 2 Aug 2010 look for the best time to sell the stock as close as possible to its highest price over 2$,T3; in mathematical terms, we look for an optimal stopping 10 Mar 2017 asset, optimal exercising of an American option, optimal stopping trend following trading, one state could correspond to "hold the stock" and
What is your optimal strategy if stock market is in a,n,b ? Obvious: buy in b, sell in a, wait in n, but only inside of (d,D). Then, we will have self-fulfilling prophecy

This paper is concerned with a finite-horizon optimal selling rule problem when the underlying stock price movements are modeled by a Markov switching Lévy process. Assuming that the transaction fee of the selling operation is a function of the underlying stock price, the optimal selling rule can be obtained by solving an optimal stopping problem. In this paper we provide an independent proof that when $\alpha = \tfrac{1} {2}\sigma ^2 $ , a selling strategy is optimal if and only if it sells the stock either at the terminal time T or at the moment when the stock price hits its maximum price so far.
optimal random time (not only stopping time) for Problem (1:2) is the last time the stock price reaches its running maximum; this motivates us that, for any selling time ˝, it might be more optimal (than ˝) to postpone the time of selling until the –rst time after (or at) ˝ that

So let’s instead consider the case where you have a 50:50 chance to recall an earlier choice. It is not surprising that this increases the optimal balance of how many candidates to consider from 37% (with no chance of recall) to 61% (with a 50:50 chance of recall) before committing to the next best choice.

Trading in stock markets consists of three major steps: select a stock, purchase a number of shares, and eventually sell them to make a profit. The timing to buy and sell is extremely crucial. A selling rule can be specified by two preselected levels: a target price and a stop-loss limit. Steeper declines result in longer shutdowns. If a 20 percent decline is reached before 1 p.m., the shutdown lasts for two hours, while trading ceases for one hour if the point is reached between 1 p.m. and 2 p.m. When the market drops by 20 percent after 2 p.m., the market closes for the day.
