IAK vs XLF

IAKBiShares U.S. Insurance ETF

XLFAState Street Financial Select Sector SPDR ETF

In short

IAK Financials, minus the banks. IAK tracks a market-cap index of U.S. insurers (life, property-casualty, brokers) in roughly 60 names, and it has run that same pure-play mandate since 2006.

XLF The 1998 original. XLF holds the S&P 500's financial sector, roughly 80 banks, insurers, card networks and exchanges, for 0.08% a year. Not the whole sector, the blue-chip end of it, and one of the most heavily traded ways to own it.

Stated mandate

IAK The fund pursues the results of an index of U.S. insurance-sector equities. It uses representative-sampling indexing rather than active management and generally places at least 80% of assets in index components.

XLF The fund seeks to track, before expenses, the price and yield performance of the Financial Select Sector Index.

Why people hold it

• IAK Insurance only. The index covers U.S. insurance-sector equities, so banks and capital-markets names do not ride along the way they do in a broad financials fund.ishares.com
• Costs 0.37% a year, below the 0.44% median for its financials peer group.
• A 2006 launch, run as a plain index sampler with no manager stock-picking, and it tracks its benchmark closely. One of the better implementations in its cohort.
• Pays out on a quarterly schedule.

• XLF At 0.08% a year, XLF sits at the cheap end of financial sector funds, well under the 0.44% cohort median and a hair below Vanguard's VFH at 0.09%.
• Trading since December 1998 and heavily traded ever since, so spreads stay tight whether you buy a hundred shares or a hundred thousand.
• Simple plumbing: it owns substantially all the stocks in the Financial Select Sector Index in index proportions, and tracks that benchmark closely.sec.gov
• One of the strongest implementations in the broad financials group on cost, tradability and index fidelity combined.

Worth knowing

• IAK About 60 stocks in one industry. Results hinge on the insurance cycle (underwriting losses, rates) rather than on the broad market.
• Whole-sector trackers like XLF and VFH charge under a tenth of a percent, so the insurance carve-out is the pricier way to own financials.
• Moderately traded and mid-size in assets, not a category heavyweight. Limit orders earn their keep here, especially in larger clips.

• XLF S&P 500 members only, so small and mid-sized regional banks are out. VFH and FNCL cast a wider net across the market-cap range.sec.gov
• About 80 names in one sector: banks, insurers, capital markets and mortgage REITs all bend to the same rate and credit cycle, so swings run wider than a total-market fund.sec.gov
• Cash comes quarterly, not monthly.
