and platinum from 1 January 2019 to 27 November 2023. The aim
was also to predict the price development of pairs of metals – gold
and silver, gold and platinum, and silver and platinum until the end
of 2024. The Nearest Neighbours method in Wolfram Mathematica
software was used to achieve the set goal. In terms of the
development of metal pairs until the end of 2024, it was found that
the most profitable pairs for investments are gold-platinum and
silver-platinum. If an investor is to invest in a single metal, platinum
is recommended. In the case of a pair of metals, it would be
appropriate to choose gold-platinum or silver-platinum. The research
is limited in terms of the metals selected, a narrower set of historical
data to make a prediction, or the selected method.
