Lack of intrinsic value, hybrid nature of commodities and recent financialization of commodity markets make of understanding precious metals price moves complicated. Predicting future development of precious metals market can be more feasible if we discover what drives these markets and describe nature of the drivers.

FinTech stocks are an important new asset class that reflects the rapidly growing FinTech sector. This paper studies the practical implications of using gold, silver, and basket-of-precious-metals (gold, silver, platinum, palladium) ETFs to diversify risk in FinTech stocks. Downside risk reduction is estimated using relative risk ratios based on CVaR. The analysis shows that gold provides the most downside risk protection. For a 5% CVaR, a 30% portfolio weight for gold reduces the downside risk by about 25%. The minimum variance and minimum correlation three-asset (FinTech, gold, and silver) p

In this paper, we present a modification of the Weibull distribution for the Value-at- Risk (VaR) estimation of investment portfolios on the precious metals market. The reason for using the Weibull distribution is the similarity of its shape to that of empirical distributions of metals returns. These distributions are unimodal, leptokurtic and have heavy tails. A portfolio analysis is carried out based on daily log-returns of four precious metals quoted on the London Metal Exchange: gold, silver, platinum and palladium.

This research is the first attempt to create machine learning (ML) algorithmic systems that would be able to automatically trade precious metals.

Abstract:

Every investor knows of precious metals - they have been reliable asset classes for years and have been a means of payment for centuries. Most popular and widely known are gold, silver, platinum, and palladium. But there are in fact eight precious metals. Today we will introduce you to the latest and rarest of the precious metals, osmium. Its outstanding characteristics have catapulted it from out of the shadows of its famous siblings right into the spotlight. And for good reasons: being the densest of all non-radioactive elements on earth, osmium is absolutely unforgeable. This, combined with

Abstract In this study, the volatility spillovers from the S&P 500 to the precious metals (gold, silver and platinum) are investigated. By using the TGARCH and DCC GARCH model, the evidence is found that there are spillovers between the S&P 500 and these global commodity markets. However, there are some differences in times of crises which have occurred during the observed 15 years (global economic crisis, debt crisis and corona crisis). In the case of gold, despite extreme volatility, there is no clear evidence of the specific influence of the crises. In contrast, silver and platinum

Abstract:

This paper aims to determine how to combine the Serbian stock index, BELEXline, with four precious metals - gold, silver, platinum and palladium, in order to minimize risk. In the process of portfolio construction, we use the theoretical concept of Markowitz. In particular, we first determine a portfolio of five assets, then exclude an asset with the lowest share and repeat the procedure till we reach a portfolio of two assets. In this way, we construct four portfolios of five, four, three and two assets. In the five-asset portfolio, the portfolio optimization process determines a zero share o

Abstract:

Exploring the hedging ability of precious metals through a novel perspective is crucial for better investment. This investigation applies the wavelet technique to study the complicated correlation between global economic policy uncertainty (GEPU) and the prices of precious metals. The empirical outcomes suggest that GEPU exerts positive influences on the prices of precious metals, indicating that precious metals could hedge against global economic policy uncertainty, which is supported by the inter-temporal capital asset pricing model (ICAPM). Among them, gold is better for long-term investmen

This research establishes the predictability and safe harbor properties of two scarce precious metals, namely, platinum and palladium. Utilizing their spot prices, the study concludes intermediate memory in the return structures of both precious metals, which implies the instability of platinum and palladium returns’ persistency in the long run. However, both the ARFIMA-FIGARCH and the ARFIMA-FIAPARCH models confirm long-memory properties in the volatility of the two spot prices. The leverage effects phenomenon is not also present based on the ARFIMA-APARCH and ARFIMA-FIAPARCH models, which ma

Preparatory research has established that internal collector smelting is an effective way to recover precious metals from the flotation concentrate of the Dukatsk deposit. This method is based on the property of lead and copper in the concentrate in an amount comparable to that of silver, to collect precious metals in a metal or matte phase in the process of segregation smelting.
