I remember reading somewhere that when indicating the state of something by using the construct <preposition > + <noun>, one should not use any article before the noun.
Based on the above rule, can I remove the ‘an’ in the following sentence without changing its meaning? Also please comment about the rule.
‘When the market is in an upward trend, investors’ loss aversion falls.’
The rule is somewhat suspicious taken out of its orginal context. Consider, this preposition + noun structure, to the store. Omitting the article renders the phrase ungrammatical, *to store.
The phrase in an upward trend is set. It needs its article.
