(ShareCast News) - Randgold Resources, a rarity of a profitable and debt-free miner, is a share to hold onto, argued the Sunday Times' Inside the City column. The west and central Africa-focused group is valued at twice the market capitalisation of FTSE 100 peer Anglo American, which is highly indebted and making losses from most of its businesses. As the price of gold shines brighter in the light of global financial jitters, Randgold has made hay and profits of $149m in the first nine months of its financial year.Whether that means Randgold is a clear buy depends on how you see the value of the yellow metal. Janet Yellen's rate setting pace in 2016 will be key. But if you want to bet on the gold price, maybe an ETF is a better tool. Having said that, Randgold has a very solid history of project delivery and decision making, helping it to an industry leading p/e ratio of 30. Whether the share price gains even more of a premium will probably be determined by the price of gold.BAE Systems shares are still worth buying, said Questor in the Sunday Telegraph, after falling from their March high last year to the point in August's where they were initial recommended and later went on to make a late surge in November. This came as BAE and its partners in the Eurofighter Typhoon project decided to cut production of the line and let it run until 2020 to try and reignite slowing demand, with Saudi Arabia seen a key potential client.BAE also contributes around 15% of each of Lockheed Martin's F-35 Lightning jets, the result of the massive joint-strike fighter program. These will be another flagship project for BAE, adding to its 40% of revenues from America as budget pressures begin to ease across the Atlantic, potentially boosting several of the group's other US contracts. The main forthcoming UK contract would be the huge nuclear submarine replacement project. Leadership remains an issue after boss Ian King announced his resignation last summer, which perhaps explains the discount the shares trade to peers.Shares in REDT Energy are a good, if risky, punt for adventurous investors, wrote Midas in the Mail on Sunday. One of the company's lead products is an innovative means of storing excess energy generated by wind and solar energy to be used when the wind is not blowing or the sun shining. Having spent years developing a commercially friendly product, REDT is accelerating production of its liquid vanadium batteries, which were invented by Nasa and can hold energy almost permanently and are now on trial with industrial customers and now cost £13,500 a pop.REDT, which was formed out of another business, Camco Clean Energy, is forecast to make modest sales of just €4.6m this year. Analysts expect sales to soar to €23.9m in 2017, with the group moving into profit shortly afterwards. While finances are currently reported in euros they are likely to swap to sterling, as REDT's facilities are near Edinburgh and Berkshire.Please note: Digital Look provides a round-up of news, tips and information that is impacting share prices and the market.
