LSK+10.6 %, moving against equities. F at +63.6 %, with MARSCOIN trailing at -3.5 %. Crypto remains the most volatile asset class covered here. Daily swings of this magnitude are normal and say little about the long-term trend.
Commodities & precious metals
All series: commodities and precious metals.
Precious metals averaged +1.0 %, energy and industrial commodities -0.5 %. That is the classic pattern of a more defensive phase: metals bid, cyclical commodities softer. Gold is a traditional hedge, while crude oil and copper act as growth barometers.

Foreign exchange (Forex)
All currency pairs are listed in the forex overview.
The key pair EUR/USD moved +0.07 %: the euro gained on the US dollar, so the dollar was relatively weaker. A firmer dollar tends to weigh on commodities and emerging markets, a weaker one supports them. Prices are drawn from CME FX futures.

|---|---|---|
  EUR/USD | 1.1523 | +0.07 % |
 GBP/USD | 1.3396 | +0.28 % |

Real assets: new hammer prices
In the window since 11 September 2026, 2 new hammer prices are on file. An auction price is not a quote: it is struck once, between two bidders, and applies to one specific item.
| Asset class | Records | Median | Highest hammer price | Price |
|---|---|---|---|---|
| Classic cars | 2 | $280,232 | Porsche 911 Turbo (964) · 1991–1994 15 Sep 2026 | $480,964 |
Median = the middle hammer price among this window's records, not the value of a fixed position. It moves simply because different items come up for sale each week. The price index below avoids exactly this composition effect. Prices are hammer prices including the buyer's premium.
No lot changed hands in trading cards in this window. The most recent recorded sale dates from 7 September 2026, 11 days back. With few, high-priced items such gaps are the norm, not a data outage. Nothing was sold at auction in watches in this window. The last sale on file is 97 days old (13 June 2026). Where trading is rare and expensive, gaps like this belong to the market rather than to a failed fetch.
The trading-card price index stands at 577.7, +215.0 % against a year ago (base 100 at the first quarter covered, as of 7 September 2026). It measures price changes of the same good rather than the median of a changing offer. Against the previous reading (29 June 2026) that is +2.3 %, a quarterly figure rather than a daily one.
Residential property: an official index, not a hammer price
For residential property there are no individual sales to report: prices there are formed in statistics, not under the hammer. The latest available reading is 1 June 2026, 109 days before this report. The gap reflects the publication lag of the sources rather than missing data.
| Series | Level | Prior print | 1 year |
|---|---|---|---|
| United States (Case-Shiller) 1 Jun 2026 | 336.7 | +0.4 % | +1.7 % |
| Germany 31 Mar 2026 | 153.4 | +0.3 % | +1.4 % |
| Euro area 31 Mar 2026 | 157.4 | +0.9 % | +4.6 % |
Cross-asset correlations
Over the past 90 trading days, EUR/USD and Gold were moderately correlated, with a correlation coefficient of +0.53. A value near +1 means they move together, near −1 they move opposite, near 0 there is no linear link. For portfolio diversification, low or negative correlations are valuable because they smooth out volatility.
| Pair | r (90d) | −1 … +1 |
|---|---|---|
| S&P 500 ↔ Bitcoin | +0.35 | |
| S&P 500 ↔ Gold | +0.40 | |
| Gold ↔ Crude oil (WTI) | -0.23 | |
| EUR/USD ↔ Gold | +0.53 |
Summary
All told, September 18, 2026 was a day of a mixed picture across the markets Alysly tracks: 78 of 97 assets gained. The headline came from Arbitrum at +24.8 %. Across asset classes, crypto led (+10.6 %) while commodities lagged (-0.5 %). The correlation between EUR/USD and Gold stood at +0.53, a gauge of how much diversification benefit combining the two currently offers. Away from the capital markets, the top hammer price was Porsche 911 Turbo (964) · 1991–1994 at $480,964, a price struck at a single table rather than on an exchange. A single trading day is only a small slice, though: over longer periods, asset classes, regions and holding period shape a portfolio's result more than any one day's move.
