ASX 200 expected to edge lower
The Australian share market looks set to edge lower on Friday following a poor night in the United States. According to the latest SPI futures, the ASX 200 is expected to open 7 points or 0.1% lower this morning. On Wall Street, the Dow Jones was down 0.25%, the S&P 500 fell 0.5%, and the Nasdaq dropped 0.8%. Tesla (NASDAQ: TSLA) shares sank 14%.
Oil prices rise
ASX 200 energy shares Santos Ltd (ASX: STO) and Karoon Energy Ltd (ASX: KAR) could have a decent finish to the week after oil prices rose overnight. According to Bloomberg, the WTI crude oil price is up 0.8% to US$63.37 a barrel and the Brent crude oil price is up 0.7% to US$65.32 a barrel. This has been driven by hopes that a US-China trade deal could be reached in the near future.
Buy Nufarm shares
The Nufarm Ltd (ASX: NUF) share price could be in the buy zone according to analysts at Bell Potter. Following a review of the agriculture sector, the broker has reaffirmed its buy rating and $3.45 price target on the agricultural chemicals company's shares. Based on its current share price of $2.10, this implies potential upside of more than 60% for investors over the next 12 months. It said: "In general crop conditions remain favourable in most markets, with recent USDA projections pointing to +2% YOY growth in global oilseed production and +1% YOY growth in global wheat forecasts."
Gold price falls
ASX 200 gold shares including Evolution Mining Ltd (ASX: EVN) and Northern Star Resources Ltd (ASX: NST) could have a poor finish to the week after the gold price fell overnight. According to CNBC, the gold futures price is down 0.6% to US$3,380.3 an ounce. Easing US-China trade war concerns put pressure on the safe haven asset.
BHP looking at nickel
BHP Group Ltd (ASX: BHP) shares will be on watch today amid reports the mining giant is looking at nickel again. According to the AFR, BHP could re-enter the nickel industry with a US$1 billion (A$1.5 billion) mine in Tanzania with the potential to be a lower cost producer than the world-beating Indonesian nickel industry. BHP's Kabanga nickel project could reportedly produce nickel for US$7,000 a tonne, which is half the current nickel price and well below its US$22,000 a tonne costs in Western Australia.
