HSBC FTSE 100 UCITS ETF

• Fund Size
  : £859.6 million
• Morningstar Medalist Rating
  : Bronze
• Ongoing Charge: 0.08%

Over the past 12 months, the HSBC fund rose 18.10%, while the average fund in its category rose 14.50%. The fund, which launched in August 2009, has climbed 16.25% over the past three years and gained 12.50% over the past five years.

The FTSE 100 Index tracks the performance of the 100 largest companies listed on the London Stock Exchange. Representing approximately 85% of the UK’s total market capitalization, it serves as a key benchmark for UK large-cap equities. The index is weighted by free-float-adjusted market capitalization and reviewed quarterly in March, June, September, and December.

Sectorwise, the index has a notable tilt toward financials, which accounts for about 25% of total assets. Consumer staples, industrials, and healthcare each contribute around 10%–15%. While the FTSE 100 Index shares a similar industry profile with its parent FTSE All-Share Index, it is more concentrated at the top. The 10 largest constituents make up roughly 45%-50% of index’s total assets. Three companies, HSBC, AstraZeneca, and Shell, each hold individual weightings above 5%.

As the large-cap segment of the FTSE All-Share Index, the index follows a transparent, rules-based methodology and is a widely used performance benchmark. However, its heavy concentration in the largest companies increases exposure to company-specific risk and can limit performance in periods when mid-cap and small-cap stocks outperform. For these reasons, the index carries a Process rating of Average.

Note: This share class’ Process Pillar rating and analysis are inherited from an analyst-covered passive share class which tracks the same index: iShares Core FTSE 100 ETF GBP Dist (SecID: F0GBR04IXF).
