Retailers saw gains on news of a cooperation agreement between Aeon (TYO: 8267) and Japan Airlines (TYO: 9205) in which the retailer will link its electronic money card to the airline’s frequent flyer miles program.

Aeon added 6.2 percent to ¥1,784, while Japan Airlines gained 4.3 percent to ¥265.

Elsewhere in the retail sector, department store operator Takashimaya (TYO: 8233) was 3.2 percent higher to ¥1,329 on better recommendations from Mizuho Securities and Nikko Citigroup.

Mizuho raised its recommendation from “reduce” to “hold”, while Nikko upped their rating on the retailer from “hold” to “buy”.

Elsewhere in the sector, Seven & I (TYO: 3382) was up 3.7 percent to ¥3,090 while supermarket chain Daiei (TYO: 8263; NAS: DAIEY) added 6.3 percent to ¥940.

Traders and commodities-related groups were higher after oil and metals prices rose overnight.

In the oil sector, Inpex (TYO: 1605) was up 3.4 percent to ¥1.21 million, while Nippon Mining (TYO: 5016) gained 2.1 percent to ¥1,177.

Among traders, Mitsubishi and Mitsui & Co. each added 1.4 percent, to ¥3,520 and ¥2,810 respectively.

Banks were lower, however. Mizuho (TYO: 8411; NYSE: MFG) was down 1.1 percent to ¥703,000 while Sumitomo Mitsui Financial (TYO: 8316) dropped 2.5 percent to ¥948,000.

Tokyo equities markets were higher on Friday. The Nikkei 225 added 1 percent to 16,536.54, it’s highest close in five months, while the Topix index added 0.9 percent to 1,628.00. The Mother’s index of small and mid-cap stocks added 5.3 percent to 1,140.02 after losses at the beginning of the week.

The retail sector saw a number of gains. Seven & I was 2.6 percent higher to ¥3,880. Aeon added 3.6 percent to ¥2,760 after it was reported that it would purchase a stake in Daiei, which was up 3.7 percent to ¥1,955 on the news. Aeon later said it would discuss buying 15 percent of Daiei. Discount retail chain Don Quijote gained 7.2 percent to ¥2,310 on an upgrade from “neutral” to “outperform” from Credit Suisse.

The major exception to the gains by retailers came from Fast Retailing, which dropped 2.90 percent to ¥11,240 even though it said its annual earnings were up by 19 percent and that they would be another 10 percent higher next year. The decline came on a downgrade from Mizuho Securities.

There were gains in the electronics sector, as well, with the exception of game machine manufacturer Sega Sammy, which fell 7.7 percent to ¥3,100 on disappointment with sales of its pachinko machines. Hitachi added 1.3 percent to ¥699, while Matsushita Electric Industrial gained 2.9 percent to ¥2,635 and Sony was 3.7 percent higher to ¥4,760 on an upgrade from “equal weight” to “overweight” from Morgan Stanley.

The Nikkei and Topix indexes both saw declines in Tokyo on Monday as domestic stocks and stocks related to the commodities markets fell on the day.

The Nikkei 225 closed below 16,000 for the first time in over two weeks as it dropped 2.3 percent to 15,877.66. The Topix index fell 2.5 percent to 1,618.01.

Mitsui Mining’s announcement that it had reduced its zinc prices led to a 7 percent drop for the company’s shares, to ¥759. Meanwhile, falling crude oil prices led to declines in upstream oil companies. Inpex lost 7.5 percent to ¥1,110,000, while Teikoku Oil fell 7.3 percent to ¥1,604. However, oil-dependent transport companies did not benefit from the drop in oil prices and both the air and sea transport sectors declined on the day. Shipper Mitsui OSK Lines fell 3.3 percent to ¥881.

On the domestic side, a wide variety of stocks declined on worries that Japan’s stock market rally would not last. The retail sector dropped 2.9 percent as a whole, while real estate fell 3.9 percent and the securities sector declined by 4.7 percent.

In the retail sector, department stores saw the brunt of the declines with Takashimaya down 4.2 percent to ¥1,649 and Matsuzakaya falling 2.5 percent to ¥989. The downgrade of retailer Daiei by Merrill Lynch from “neutral” to “sell” sent shares in that company down 12.4 percent to ¥3,540.

Real estate company Tokyu Land dropped 4 percent to ¥1,112, while in the securities sector Daiwa Securities fell 6.6 percent to end at ¥1,263.
