It has been a busy day for results from FTSE 100 heavyweights and the reception for most of them was far from warm.Sweeteners manufacturer Tate & Lyle became the biggest faller among Footsie constituents after reporting a mixed performance in the third quarter, with subdued volume growth in several divisions. The firm, nevertheless, said it remains on track for a "good performance" in the full-year. JP Morgan and Jefferies have both reiterated their underperform ratings on the company´s shares. Property group British Land was also among the worst performers despite seeing occupancy, income, estimated rental value and underlying profits rise in the third quarter. Rolls-Royce was similarly out of favour despite 2011 being a record-breaking year on many fronts. The power systems developer saw underlying profit before tax rose 21%, while underlying revenue edged up 4%. Mining giant Rio Tinto also slipped after saying that full-year net earnings were held back by a massive $8.9bn impairment charge relating to its aluminium business. Nevertheless, underlying earnings rose 11% to a record $15.5bn. Shares in investment firm Hargreaves Lansdown also took a plunge, even though the firm boasted record revenue and profits in the second half of 2011 despite a sharp deterioration in investor confidence. Meanwhile, BG Group was among the risers after higher oil prices helped earnings before tax shoot up by 40% on last year in the fourth quarter. The group also gave a confident outlook for the LNG market, hiking its LNG profit guidance by 30% for 2012. Sector peers BP, Cairn Energy, Tullow Oil and Essar Energy were also in demand, buoyed by today's rise in brent crude prices.
