Shares in telecoms giant Vodafone were on the rise on Tuesday after UBS highlighted the possibility of a bid from US cable operator Liberty Global.The Swiss bank maintained a 'buy' rating and 265p target price on the UK-listed stock, saying that Liberty may be revisiting its strategy. Nevertheless, regardless of a hypothetical deal, UBS said that Vodafone's stock is still cheap and fundamentals at the business are improving.Antofagasta's stock should outperform, according to analysts at Jefferies, with the copper miner approaching a "strategic inflection point".The broker reiterated a 'buy' rating and 900p target price for the shares. "Antofagasta has significant advantages versus other miners for now but longer-term disadvantages which should be addressed (potentially via M&A). All things considered, we expect Anto's strengths to lead to share price outperformance during the current period of macro weakness."JPMorgan Cazenove has downgraded its recommendation for British Airways owner IAG from 'overweight' to 'neutral' after reassessing its stance on the European airlines sector.The bank said it favours low-cost carriers strongly over legacy airlines due to "superior risk/reward and continued growth potential", as it upgraded its rating on Ryanair from 'neutral' to 'overweight', retained its 'overweight' stance on Easyjet and initiated coverage on Wizz Air at 'overweight'.
