Financial services adviser Hargreaves Lansdown is expected to report a 17 per cent year-on-year rise in revenues of 164.5m pounds in its interim results on Wednesday, according to Charles Stanley. Investors will also be focusing on whether the Royal Mail's initial public offering boosted results.Numis said that it sees the company delivering another strong performance through the year."We believe current trading is very strong and given the buoyant market conditions we expect very good growth through the key ISA and tax year period," the broker said."We need to see what if any customer behaviour changes occur as a consequence of the coming pricing changes."GlaxoSmithKline and Homeserve are also out with interims. Following the earnings session, a batch of data on the service industry in the Eurozone and the UK will be released.In the US, the ISM non-manufacturing composite is out along with weekly mortgage application figures and the ADP Employment report.Following Monday´s shockingly weak ISM manufacturing report Stateside traders will likely be on guard against any further weather-induced distortions in the data.Nevertheless, even under normal conditions the ADP report often results in a notable pick-up in levels of intra-day volatility. As well, should there by any negative surprise forthcoming that could affect expectations heading into Friday´s monthly employment report. Investors are closely watching indicators linked to the labour market at the moment in the aftermath of December´s much weaker than expected reading on non-farm payrolls.
