Industrials & Defense Thematic basket

Defense & Aerospace

Rearmament as a secular budget line: primes, shipbuilding, aero suppliers, defense IT and software, and the commercial aero duopoly’s troubled half. Geopolitical risk-on basket — it works when nothing else does.

How these statistics are calculated

Risk methodology

Sharpe: average daily simple return divided by its sample standard deviation, multiplied by √252. The risk-free rate is assumed to be 0%; this is not a cash-adjusted ratio.

Sortino: average daily simple return divided by downside deviation, multiplied by √252. Downside deviation is the square root of the average squared shortfall below 0%, counting all sessions, including zeros for gains.

Historical volatility: √(252 × average squared daily log return), matching the Vol page’s realized-volatility convention. This differs from the sample standard deviation used in Sharpe.

Each period requires complete history and at least 5 sessions. MTD and YTD follow the calendar; 1y is 252 sessions. Missing data or an undefined ratio displays — with a reason. Short periods can produce unstable ratios; intraday snapshots include a partial session. History before this basket’s creation is backtested. If a new basket has no stored daily return series yet, estimates from its rounded published chart levels are marked ≈.

Reading the returns

Basket returns include dividends. “vs S&P 500” compares the basket’s compounded growth with the benchmark’s. Green means positive; red means negative.

Cross-checked against ITA. Daily return correlation: 0.95 across 1710 sessions. cap-weighted vs our equal weight; otherwise a close universe match

Membership history & changes

Membership history

  • expand

    FW 3000 pass: added HEI, CW, CACI, BAH, SAIC, KTOS, AVAV, RKLB — names outside the S&P 500 but inside our broad universe; they count only in the FW 3000 version of this basket. Effective-dated to creation so the broad backtest covers the full set. The S&P 500 basket is unchanged.

  • expand

    Widening pass: added the defense-IT/software leg (LDOS, PLTR), public-safety tech (AXON), and Textron — the full S&P 500 aerospace & defense sub-industry plus software. Reference pinned to ITA. New members are effective-dated to basket creation so the backtest and the reference correlation cover the widened set (the basket was one day old, with no meaningful live history to restate).

  • create

    Initial composition: primes + aero supply chain.
