The Jakarta Composite Index today, on Friday (29/1), is expected to weaken.

"JCI movement seen to fall because the market was waiting for the announcement of US Advance GDP. The government policy in extending the PPKM period, as well as the increase in COVID-19 cases, has the potential to provide negative sentiment for the market," said Binaartha Sekuritas analyst Nafan Aji in her research.

On the other hand, Nafan also said several downward bar patterns indicate potential further weakness in the JCI movement.

Nafan estimates that today's JCI movement is based on the Fibonacci ratios, while support and resistance are 5,853.26 and 6,064.55, respectively.
