CAC 40 Index (FRA40) Trading Guide 2024

The FRA40 contract carries a pip size of 1 and a pip value of 1, with a contract size of 1 — a straightforward structure that simplifies position sizing calculations. At a typical spread of 1.5 pips, a round-trip trade costs 3 pip-equivalents in spread alone, meaning the index must move at least 3 full points before a position breaks even on spread costs. The CAC 40 historically averages daily ranges between 60 and 120 points during normal market conditions, expanding to 200+ points on high-impact macro events such as ECB rate decisions or French election results. Constituents are heavily weighted toward luxury goods (LVMH, Hermès, Kering collectively represent roughly 25% of the index as of 2023), energy (TotalEnergies), and financials (BNP Paribas, Société Générale). This sector concentration means the index responds sharply to global luxury demand data from China — a factor that distinguishes FRA40 from DAX or FTSE 100 behavior. Research from Euronext indicates average daily turnover on CAC 40 futures exceeds €8 billion, providing deep liquidity during European hours. Thin liquidity during the pre-market window (01:15–07:00 UTC) can produce wider effective spreads than the stated 1.5 pips, particularly ahead of Asian session closes.

A counterintuitive finding among professional index traders: the first 30 minutes of the Regular session (07:00–07:30 UTC) frequently produce the day's largest single directional move, yet also carry the highest false-breakout rate. The Regular session runs 07:00–15:30 UTC, aligning the CAC 40 with simultaneous activity across DAX, FTSE 100, and — from 13:30 UTC onward — US equity futures. This overlap between 13:30 and 15:30 UTC historically produces the highest average true range per 15-minute bar. According to data compiled by the CME Group on correlated European index behavior, the 60-minute window surrounding the US market open (13:30 UTC) accounts for approximately 35% of total intraday range on average European index sessions. The Extended session (15:30–22:00 UTC) sees declining volume from European participants but remains active due to US equity correlation — the CAC 40 will track S&P 500 moves with a correlation coefficient that has averaged 0.78 over the past five years. Pre-market hours (01:15–07:00 UTC) are primarily driven by overnight Asian sentiment and futures positioning; price gaps at the 07:00 UTC open are common after significant moves in Nikkei or Hang Seng. Traders focused on momentum strategies tend to concentrate activity between 08:00 and 10:30 UTC, when European institutional order flow is at its peak and price discovery is most efficient.

With a pip value of 1, calculating risk on FRA40 is arithmetic. A stop-loss placed 50 points below entry on a single contract risks exactly $50. Scaling to 5 contracts raises that exposure to $250 on the same stop distance. This linear relationship makes the index well-suited to percentage-of-account risk models: a $10,000 account risking 1% per trade ($100) can hold a 2-contract position with a 50-point stop, or a 1-contract position with a 100-point stop. The index's average true range of 80 points on a standard session means stops tighter than 25–30 points face high noise-driven stop-out rates, particularly during the volatile open. A practical benchmark: stops placed inside 20 points of entry during the 07:00–09:00 UTC window are stopped out by normal volatility more than 60% of the time, according to backtesting analysis on European index intraday patterns published in 2022. Correlation risk deserves attention. Holding simultaneous long positions in FRA40, DAX (GER40), and FTSE 100 does not constitute diversification — these three indices carried a 30-day rolling correlation above 0.85 for 74% of trading days in 2023. Sizing each position as if it were independent significantly underestimates aggregate portfolio risk.
