Read the sentences given below carefully and identify the one that contains a grammatical or contextual error. If all the sentences are grammatically and contextually accurate, select the "all are correct" option.

The correct option is: "I don't expect the stock to make any significant recover back until the trading volume starts picking up steadily."

Detailed Explanation:
The sentence contains both a grammatical error and a redundant phrasing error in "significant recover back":

1. Part of Speech Error: The modifier "significant" is an adjective, which should qualify a noun. The verb "recover" is used here incorrectly instead of its noun form, "recovery".
2. Redundancy: Using "back" along with "recover/recovery" is redundant because the concept of returning or regaining a previous position is already built into the definition of "recovery".

Correct Version:
"I don't expect the stock to make any significant recovery until the trading volume starts picking up steadily."

All other given options are contextually and grammatically correct.
