I know that "however" can be used to contrast a sentence against the preceding sentence. Is the use of "however" in the following sentences correct?
The [name of channel] channel is found to be the most important for [name of some financial market] However, the overall effect of the [name of some channel] channel appears to be minor for [name of some other financial market]
In other words: is "the most important" really a contrast to "appears to be minor"?
