CHICAGO (Dow Jones)--Chicago Mercantile Exchange live cattle ended weaker Monday on spreaders who sold February and bought December, sell stops and lower prices in corn at the Chicago Board of Trade.

Most feeder cattle contracts finished firm. Lean hogs landed in positive trading territory. And, pork bellies closed limit up.

Live cattle initially spiked, driven by leftover enthusiasm from last week's surprisingly strong cash cattle results. Buy stops and the overnight run-up in U.S. stocks also generated early morning cattle-buying interest.

Persistent boxed beef price gains and someone who willingly accepted late-Friday's CME live cattle deliveries motivated initial futures buyers.

However, spot-October slowly eased back when more sellers emerged, while those in the cash cattle sector prepared to set the tone for this week's cash cattle trade.

Cash-basis cattle last week sold mostly at $85.50 to $86 per hundredweight, compared with the bulk of cattle that brought $84 a week earlier.

Nearby December ran into resistance at the 100-day moving average and later triggered sell stops when the contract slipped below recent session lows.

Also, overbought conditions in the October and December Relative Strength Index fractured buying interest in both months.

Meanwhile, the U.S. dollar's rebound and the retreat in U.S. equities discouraged bulls in distant cattle months.

Traders on Tuesday will await fed cattle bids and asking prices. Market participants also will watch for possible CME live cattle deliveries ahead of spot October expiration on Oct. 30.

October live cattle settled down 22 points at 86.12 cents a pound, and December closed down 25 points at 87.15 cents.

Feeder cattle closed mostly firm on spreading into January and out of October that will expire on Oct. 29. November also triggered buy stops after the contract earlier bounced off 10-day moving average support.

The sharp decline in CBOT corn marshaled CME feeder cattle longs.

October feeder cattle settled down 40 points at 93.85 cents, and November closed up 40 points at 95.87 cents. January finished up 20 points at 96.00 cents.

Pork Complex

CME hogs settled firm on late-day short-covering, forward positioning and buy stops after February reclaimed support at the 10-day moving average that it had lost earlier.

Lean hogs opened in two-tiered fashion. December through April began the morning on a positive note from the overnight rise in U.S. equities and the dollar's initial slump.

Late-Friday's pork cutout price increase and steady terminal hog market values inspired December and February buyers, and sent market shorts scrambling to cover previously held positions.

And December, whose Friday settlement was in line with CME's hog index, attracted prospective market bulls.

However, December took back opening gains due amid uneasiness over cash hog prices that faded as the morning wore on. And February longs were less aggressive about buying the contract, which was already technically overbought before the open.

Nonetheless, speculative buyers bought market breaks despite the eventual downturn in U.S. stocks and the dollar's bounce.

Steady cash hog bids are forecast for Monday. Packers are expected to keep a floor beneath cash hog bids as long as margins improve and pork cutout values stabilize.

December hogs ended up 42 points at 53.45 cents a pound, and February finished up 37 points at 60.82 cents.

Pork bellies closed limit up on continued buying from futures' surge on Friday, buy stops and lean hogs' late-day upturn.

Friday's higher fresh belly quote contributed to belly contracts' bullish outcome Monday.

CME's weekly belly storage report will be released on Tuesday after 5 p.m. EDT.

February pork bellies ended 300 points higher at 88.97 cents a pound. March was unquoted. May also finished up 300 points at 88.45 cents.
