In the firm's words
  • Quantitative / systematic: Quantitative analysis deals with measurable factors such as the value of assets, the cost of capital, historical projections of sales, and so on.
  • Fundamental active: Fundamental analysis involves the analysis of financial statements, the general financial health of companies, and/or the analysis of management or competitive advantages.
  • Value: This strategy would normally encourage equity purchases in stocks that are undervalued or priced below their perceived value.
  • Multi-asset: Modern Portfolio Theory seeks to maximize expected return for a given level of risk—or minimize risk for a given expected return—by selecting the right mix of assets.
  • Long/short hedge: Stirlingshire uses long-term trading, short-term trading, short sales, margin transactions and options trading.

How the bands are measured

Style bands measure the filed 13F common-share book each closed quarter, tested in this order. Unknown: under $10,000,000 of valued equity or 5 stocks. Index-like (100+ stocks): active share of 20% or less against the closest benchmark, which is the S&P 500, S&P MidCap 400, S&P SmallCap 600, Russell 1000, Russell 2000, Nasdaq-100 or Dow Jones Industrial Average (weighted by an index-tracking fund's reported holdings or the index's constituents nearest the quarter end, over the names resolved to companies, and only when those are 90%+ of its weight) or every 13F filer's combined book, or index series holding 80%+ of the registered fund assets it advises (N-CEN) and equal to 50%+ of its book. Systematic-like: 500+ stocks, 100%+ annual turnover and a top 10 weight of 25% or less. Concentrated: a top 10 weight of 60%+ or 12 or fewer effective positions. Diversified active: none of these. Turnover is the smaller of buys and sells over average equity value, summed over four quarters: low under 30%, high 100%+. Horizon is the value-weighted number of quarters each position has been held: short under 4, long 12+.

Covers the securities this platform tracks: U.S.-listed common stock and the put/call positions reported on it. A 13F can also report security types outside that coverage — preferred shares, bonds, warrants, untracked share classes — so the filing's own declared total can exceed the figures above. The source filing is linked at the top of this table.
