| 释义 | chartist noun[ C ] uk /ˈtʃɑːtɪst/us FINANCE a person who uses charts and computer programs to look at how the prices of shares have gone up and down in the past, in order to say how they might change in the future: The BT price chart shows how a chartist could have spotted the end of a two-year rise in BT shares. Examples of chartistchartist This may be the case when a market with a high concentration of chartists displays a strong technical trading signal. In contrast, chartists use rather flexible extrapolative methods to forecast prices. Our model is flexible enough to capture chartist behavior. If g goes to infinity, all chartists enter the market with the highest fitness. However, every chartist knows that all bubbles eventually burst. Broadly speaking, chartists tend to destabilize the markets, whereas fundamentalists exercise a stabilizing impact on the dynamics. Since chartists typically destabilize the market, a bubble is likely to occur. We want to keep a total of the gains obtained up to period t by following the fundamentalist rule and similarly for the chartist rule. The higher the attractiveness of market k, the more chartists will enter that market. For instance, if the market impact of chartists exceeds a critical threshold, prices may be driven away from fundamentals. In addition, it is sometimes conjectured that chartist-fundamentalist models have difficulties in mimicking the stylized fact of financial markets in a nonstationary setting. Furthermore, the market forecasts will evolve as the proportions of fundamentalists and chartists change over time. Specifically, chartists prefer markets that display price trends but that are not too misaligned. The delay effect reflects the presence of chartists. For g = 0, the chartists do not observe any differences in the fitness of the markets. See all examples of chartist These examples are from corpora and from sources on the web.
