Quotations of contracts for US indices pointed to a downward start on Wall Street. The opening on Wall Street is downward, but the market is not much lower compared to yesterday at the same time, S&P 500 hovering below the level of 2000. Weaker US performance seems to be mimicked by the Warsaw Exchange. The supply side is increasingly prominent in shares that have the greatest negative impact on the WIG20. In the case of PKN Orlen, we can see descent to new session minimum, while turnover has already exceeded 100 mln PLN, and at the end of the day will probably be higher than yesterday. Very similar pressure also applies to KGHM, and in the last minutes to Pekao.
