Abstract
Overnight returns are significantly positive while day returns are significantly negative in the COMEX gold front futures contract, the gold spot market (London Fix), gold mining company stocks, and gold related closed end mutual funds and exchange traded funds. The findings are consistent with gold price being (too) high at the opening of the various markets. The asymmetry is shown to be present in both up and down markets for gold. The results are economically important even with transaction costs.

Notes
The S&P 500 declined 50.5% over the period March 2000 through October 2002 and declined 57.7% over the period October 2007 through March 2009.
See O’Connell et al. (2017) GFMS Gold Survey 2017. Dollar value is calculated using $1250.60 per ounce - the 2016 average price of gold. Jewelry is reported because at least some Jewelry purchases represent gold investment.
Daily bond Equivalent Yields on 4-week T-Bills obtained from https://www.federalreserve.gov/ releases/h15/update/ . The S&P 500 increased at a geometrical average annual rate of 8.24% over the 30 year period.
We set these dates as the beginning and end of the bull market based on the high and low settlement prices on the COMEX front future contract (see Figure 1). The high and low prices for the London PM fix were on different dates. The low was 252.8 on July 20, 1999 and the high was 1895.0 on September 6, 2011;
COMEX ended open outcry trading in gold in July 2015. All contracts are now traded on an electronic platform.
Observe from the start dates of the funds in Table 6, that from 7/01/85 through 03/17/92 there was only one stock in the equally weighted portfolio. The company, ASA Gold and Precious Metals, invests in gold, silver, platinum, and diamond mining companies. Accordingly the company is unlikely to have the sensitivity to gold price that would be present in the companies only investing in gold mining companies and gold bullion. The returns for ASA are the only returns affecting the first seven years of the 30 year period and can be expected to have a substantial effect on the returns during that longer period.
We surveyed nine retail stock brokers and nine retail futures brokers to get an estimate of brokers fees. The most expensive stock brokerage fee was $9.99 and the least expensive was $4.00. The cost of a futures trade of one contract ranged from $1.00 to $9.70. The cost per futures contract declines substantially as the number of contracts traded increases.
For small trades of a few hundred shares, the transaction cost per share declines as the size of the order increases. Wagner and Glass (2001) argue that for larger trades there are additional costs that are often overlooked that can be greater than the broker’s fees. These include market impact costs, the cost of delaying an order until liquidity develops, and the opportunity cost associated with not trading or only partially completing an order. These costs will depend upon the size of the trade and the liquidity of the market and will increase as the size and difficulty of the trade increases.
In May and June 2013, India installed a series of restrictions on the importation of gold. The restrictions were designed to address balance of trade and currency issues associated with gold imports. In 2012 India imported 860 tons of gold making it the largest importer of gold in the world. The restrictions were eased in November 2014.
