Copper giant Antofagasta (LON:ANTO) is picked up by Liberum today, which repeated a 'sell' stance on the mining share.
It does not expect to see a "sustained" recovery in the copper price until the inflection point of supply and demand in 2017 as China's economy shifts over the next two years to services rather than investment.
But analyst Richard Knights is more upbeat short term :"However, in the short term the risk to sentiment may become more balanced as the suffering producers up the ante on the longer term supply risks from project cancellations and capacity cuts."
He says Anto and Kaz (LON:KAZ) have both reached their respective price targets and are at fair value.
"We upgrade KAZ Minerals to HOLD; however, for Antofagasta we see further derating potential and maintain a SELL rating."
Citigroup takes a red pen to travel giant Thomas Cook (LON:TCG) and slashes the price target to 115p from 150p saying it remained "fundamentally bearish" on the medium term outlook for the group.
In its third quarter numbers posted at the end of July, the firm told investors that the recent tragic events in Tunisia, and concerns regarding Greece's potential exit from the euro, were expected to reduce 2015 earnings before interest and tax by around £25 million.
Citi has reduced its 2015/16/17 earnings per shae (EPS) forecasts by 28%/33%/35% to reflect guidance on Tunisia/Greece costs and greater caution on management’s ability to deliver future cost savings, it said.
"While Tunisia is a small market for TCG (less than 5% of PAX) it remains a key winter destination," noted analyst James Ainley. Citi repeats a 'neutral' stance.
Elsewhere, chip designer ARM Holdings (LON:ARM) has its wings clipped by heavyweight JP Morgan Cazenove, which has reduced the price target to 850p from 900p.
The rating is 'underweight' as the broker has reduced its revenue estimates for 2016 on the back of the continued weak semi-conductor market.
The broker's main cut is to processor royalty revenue, which it now sees growing at 12% against 18.5% previously.
US broker Jefferies is not so keen on temporary power giant Aggreko (LON:AGK) after last week's half year numbers and has repeated an 'underperform' stance and dropped the target price to 950p from 1,100p.
The Glasgow-based firm reported a 21% fall in pre-tax profits and said it expects trading to be difficult for the rest of the year as it identified cost savings of £80mln to be made by 2017.
It confirmed it expects full-year profits are likely to be between £250mln and £270mln, which is at least 8% lower than previously forecast in a poll of business analysts.
Jefferies noted: "Cost savings look sensible but investment in new technologies send a mixed message at this point in the cycle by reducing returns ratios. We continue to see structural and cyclical pressures on rate which negatively impact our bottom of the range EPS estimates."
Finally, FTSE250 construction group Balfour Beatty (LON:BBY) was buoyed by RBC Capital Markets, which upgraded the shares to 'outperform' from 'sector perform' and kicked up the price target to 300p from 200p.
Balfour shares added 1.41% to 245.10p on the day.
