CANBERRA, Aug 7 (Reuters) - Chicago wheat futures rose on Thursday after ample supply and the placing of bearish bets by speculators powered a weeks-long sell-off that drove prices to a five-year low on Wednesday.
Corn futures also gained after falling to contract lows in the previous session, and soybeans edged up from their lowest price levels since April. As with wheat, global supply of both crops is plentiful.
